Deterministic, no downloads, perfect for tests. + +### 6. Schema Introspection + +SQLAlchemy ORM models are introspected at runtime to produce natural language schema descriptions: + +```python +>>> env._get_table_schema('Student') +Table 'Student' has the following columns: + +- student_id: integer number +- student_details: text (up to 255 characters) + +>>> env._get_table_schema('NonexistentTable') +Table 'NonexistentTable' not found in schema. +``` + +9 tables available: Address, Person, Student, Course, PersonAddress, StudentCourseRegistration, StudentCourseAttendance, Candidate, CandidateAssessment. + +### 7.

Returns initial `SQLObservation`. +- **`step(action)`** — Dispatches on `action.action_type`. Appends assistant response to `history_messages`, stores action tokens in `history_tokens`. Returns flattened observation. +- **`message_to_action(message)`** — Server-side conversion of `Message` dict → `SQLAction`. Detects action type via keywords, appends message to state history, tokenizes full conversation. +- **`_detect_action_type(content)`** — Keyword classifier: checks for "describe"/"schema"/"columns" → `describe`, "sample"/"example"/"rows" → `sample`, default → `query`. +- **`_create_observation()`** — Builds `SQLObservation` from current state. Flattens all `history_tokens` into a single 1D tensor via `torch.cat`. +- **`_get_table_schema(table_name)`** — Introspects SQLAlchemy model columns, converts types to natural language. +- **`_call_ollama_for_sql(query)`** / **`_call_ollama_to_select_table(request)`** — HTTP POST to Ollama `/api/generate`. + +**Constructor params:** `tokenizer` (must have `apply_chat_template`), optional `system_prompt`, optional `transform`. + +**Environment variables:** `OLLAMA_MODEL` (default: `qwen2`), `OLLAMA_BASE_URL` (default: `http://localhost:11434`). + +### 2. `SQLEnvClient` — `envs/sql_env/client.py` + +WebSocket client extending OpenEnv's `EnvClient[SQLAction, SQLObservation, SQLState]`.

Spider Question Data — `envs/sql_env/data/questions/student_assessment.json` + +3,355-line JSON file containing 30+ question-answer pairs from the Spider dataset. Each entry includes: +- `db_id` — always `student_assessment` +- `question` — natural language question (e.g., "which course has most number of registered students?") +- `query` — gold SQL (e.g., `SELECT T1.course_name FROM courses AS T1 JOIN student_course_registrations...`) +- `query_toks` / `query_toks_no_value` / `question_toks` — tokenized versions + +### 6. Data Preparation Scripts — `envs/sql_env/scripts/` + +- **`download_spider_data.py`** — CLI tool to download Spider questions from HuggingFace.

This means calling it has a side effect — it's not a pure function. If you call it twice with the same message, you'll get duplicate entries in history. + +- **Client vs Server `message_to_action` diverge:** The server version (`sql_environment.py:message_to_action`) manages state internally and mutates `_state`. The client version (`client.py:message_to_action`) requires passing `history_messages` explicitly and does not manage state. They have different signatures. + +- **Schema description is hardcoded in `sql_environment.py`:** The `_build_schema_description()` function returns a fixed string with table/column names that don't perfectly match the SQLAlchemy ORM models. For example, the schema description says `Students (student_id, person_id, student_acc_status)` but the ORM model has `Students (student_id, student_details)`. + +- **Ollama failure mode is silent:** If Ollama is unreachable, `_call_ollama_to_select_table()` catches all exceptions and returns the *first table in the dict* (`Address`). No error is surfaced to the caller. `_call_ollama_for_sql()` returns an error string, but it's treated as a normal assistant message. + +- **Original observation fields are commented out, not deleted:** `SQLObservation` still has `question`, `schema_info`, `result`, `error`, `step_count`, `budget_remaining`, and `action_history` as comments. They're intended to return in a later phase. + +- **`MockTokenizer` is imported by production code:** `app.py` imports `MockTokenizer` from `test_sql_env.py` at runtime when `transformers` is missing.

The difference between checkpoints is **within run-to-run variation** (~6-8pp swing). For the blog, report both as "~28-32% accuracy" or "roughly 30%" rather than claiming one is better. The meaningful comparison is GRPO (~30%) vs base model (0-2%), not v1 vs v2. + +The variation comes from: (1) temperature sampling during generation, (2) question selection randomness at N=50, (3) v2's "Task complete." abstention pattern — on borderline questions, whether v2 guesses or abstains varies by run, causing larger accuracy swings. + +Note: parse failures no longer end episodes — model gets a no-op DESCRIBE and continues. This gives base models the same step budget as trained models, but they waste it on repeated parse failures (avg 11-15 steps vs GRPO's 3.5-4.0). + +### Key observations from N=50 eval (with retry, 2 runs) +1. **~30% accuracy** for GRPO vs 0-2% for base model across all conditions. v1 and v2 are statistically indistinguishable (28-30% vs 24-32% across runs). +2. **Run-to-run variation is ~6-8pp** — v1 scored 28% then 30%, v2 scored 32% then 24%. At N=50, don't over-interpret small differences between checkpoints. +3. **Base model parse failure loop** — without episode termination on parse failure, base models burn their entire 15-step budget repeating the same non-tool-call output (e.g., "- Single value: []" 11 times). 46-49/50 1-shot episodes hit budget exhaustion. +4. **GRPO solves format compliance** — 95-100% parse rate (v1) vs 17-28% for base. The trained model almost always produces valid `` JSON. +5. **GRPO failure mode is SQL quality, not format** — episodes with correct tool-call format but wrong SQL/answer dominate GRPO failures. +6. **Extra turns don't help base models** — more steps just mean more repeated failures. The fundamental gap is format compliance, not exploration budget. +7. **1-shot occasionally gets lucky** — scored 2% in Run B (1/50 correct), 0% in Run A. At N=50, a single lucky episode swings accuracy by 2pp. + +### v2 vs v1: similar accuracy, more parse failures — behavioral shift +Across two runs, v1 and v2 show overlapping accuracy ranges (28-30% vs 24-32%). The difference is within run-to-run variation at N=50. However, v2 consistently shows more parse failures (8-22 vs 0-8), revealing a behavioral shift from continued training: + +- **v1 guesses more**: v1 almost always calls `answer()`, even when uncertain. It submits wrong answers confidently (0 parse failures in Run B, 100% parse rate). +- **v2 gives up on hard questions**: v2 produces "Task complete." output after multiple failed queries instead of calling `answer()`, producing parse failures. v2 learned that some questions are unsolvable. +- **Neither is clearly better**: v2's caution helps on some runs (32% in Run A) and hurts on others (24% in Run B). The abstention behavior adds variance. For the blog, present them as equivalent (~30%) with a qualitative note about the behavioral difference. + +The v2 parse failure pattern (from raw output): +``` +[OK] DESCRIBE: country +[OK] QUERY: SELECT Name FROM country WHERE Population < ... +[PARSE FAIL] raw: Task complete. ← gives up, doesn't call answer() +[PARSE FAIL] raw: Task complete. ← repeats until budget +``` + +Compare v1 on the same type of question: +``` +[OK] DESCRIBE: country +[OK] QUERY: SELECT Name FROM country WHERE ... +[OK] ANSWER: European cities and their names are: 42 ← wrong, but at least calls answer() +``` + +This is a form of **calibrated uncertainty** — v2 is better at knowing what it doesn't know. The incorrect answer reward of 0.0 (see learning #19 in session log) creates an avoid-answering incentive that v2 has partially internalized. A more generous incorrect-answer reward (e.g., +0.1 for attempting an answer in correct format) might recover these episodes. + +### For the blog narrative +The story is clear: GRPO teaches format compliance (0% → 95-100% parse rate) and strategic tool use (describe→query→answer in 3-4 steps). Base models waste 15 steps repeating parse failures. The ~30% accuracy ceiling (consistent across checkpoints and runs) comes from the 0.6B model's SQL reasoning capacity, not from the environment or training pipeline. The environment scales; the model doesn't. Report v1 and v2 as "roughly 30%" — the variation between runs is larger than the difference between checkpoints. + +## Format Mismatch Discovery (F011) + +### The three differences between eval and training +1. **role:tool vs role:user** — Qwen3 renders `role:"tool"` as `<|im_start|>user\n...`, `role:"user"` as `<|im_start|>user\nplain text`. Same role token, different content structure. +2. **Structured tool_calls vs raw text** — Training uses `{"role":"assistant", "tool_calls":[{"function":{"name":"describe","arguments":"{...}"}}]}`, eval was using `{"role":"assistant", "content":"..."}`. +3. **No separator vs `\n\n`** — TRL appends `reset()` return directly to user message. Eval had `question\n\ntable_hint`. + +### Impact +Before fix: 0% accuracy across ALL conditions (zero-shot, 1-shot, 3-shot, GRPO checkpoint). +After fix: 10% zero-shot, 30% 1-shot, 50% 3-shot on base model. GRPO checkpoint still 10%. + +### Lesson +Eval format matching is not a nice-to-have. It's a prerequisite for ANY measurement. We spent time debugging model quality when the problem was plumbing. + +## Multi-Turn SFT — Why It's Critical + +### Per-turn SFT (broken) +- 347 examples, each one assistant turn +- ~50% were describe calls +- Model learned: "when asked a question, call describe" +- With KL penalty, model stayed anchored to this single-action policy +- Result: reward=0.00, all rollouts identical, advantage=0 + +### Multi-turn SFT (working) +- 120 examples, each a full describe→query→answer trajectory +- `assistant_only_loss` via Qwen3 template patch (`{% generation %}` tags) +- Model learned: the SEQUENCE describe→query→answer +- With KL penalty, model explores within the multi-turn strategy +- Result: reward climbs to 0.7 in Phase 1 + +### Template patch detail +Qwen3's chat template lacks `{% generation %}` tags needed by TRL for assistant_only_loss. We patch the template before SFT, restore original before GRPO (TRL does exact-match checks on template string in `add_response_schema()` and `get_training_chat_template()`). + +## The 0.6B Capacity Ceiling + +### What works at 0.6B +- Single-table queries: COUNT, SUM, AVG, MIN, MAX, GROUP BY, HAVING, ORDER BY, LIMIT +- Simple JOINs between 2 tables when FK is obvious (evaluation.Employee_ID = employee.Employee_ID) +- WHERE with LIKE, IN, BETWEEN, NOT IN subqueries +- Answer formatting: comma lists, pipe-delimited rows, `[]` for empty +- Error recovery: describe after SQL error, retry with correct column names +- `sample` tool usage (learned in Run 6, inconsistent later) + +### What breaks at 0.6B +- FK chain reasoning: 3+ table joins (Documents→Templates→Ref_Template_Types) +- Column name fidelity: reads `FullName` from describe, writes `full_name` in SQL +- Ambiguous column resolution: joins with same column name in both tables +- Complex subqueries: INTERSECT, EXCEPT, correlated subqueries with HAVING +- "stadium without concert" pattern: NOT IN with JOIN to get names +- Aggregate + GROUP BY + HAVING chains on multi-table joins + +### The hallucination pattern +The model describes a table and sees the exact column names. Then it writes SQL using pretrained column names that don't match. This isn't a memory problem — the schema is in the context window. It's a weight problem — pretraining biases override in-context information at 0.6B scale. + +## Thinking Mode Observations (Run 8) + +### Benefits +- Reasons through SQL errors: "no such column: airport_code" → `` block → tries `AirportCode` +- Empty `` on easy questions — token-efficient, emergent behavior +- Multi-step join planning in think blocks + +### New failure mode +~23% of rollouts: `assistantassistant...` repeating until token limit.

Phase 2 crashed at step 182/467 with max_new_tokens=1280. Fix: reduce to 1024, or reduce num_generations from 4 to 3. + +## Narrative Threads for Blog + +### "The environment is the product" +From VISION.md: "SQLEnv is a reinforcement learning environment — not a text-to-SQL model. The environment is the product." The trained agent demonstrates that the environment works, but the contribution is the action space, reward architecture, and episode structure. + +### "Small model showing improvement proves more than large model with marginal gains" +A 0.6B model going from 0% to 10% accuracy with clear strategic behavior (describe→query→answer, error recovery) proves the environment produces learning signal. A 70B model with marginal gains would prove nothing about the environment. + +### "Analysts don't write perfect queries from scratch" +The hook. Frame the problem as: text-to-SQL evaluates guessing, not investigating. SQLEnv evaluates the process. + +### "Dense rewards need theory" +Potential-based shaping isn't just good practice — it's the guarantee that the agent optimizes for the right objective. Without it, we saw agents farming exploration rewards. + +### "Multi-turn SFT teaches strategy, not actions" +The difference between per-turn and multi-turn SFT is the difference between teaching vocabulary and teaching conversation. + +## References for Blog + +- Ng, Harada, Russell (1999).

SQLEnv: Teaching Small Models to Explore Databases Like Analysts

Untrained vs Trained Agent

+(+) QUERY ...JOIN...ORDER BY Bonus DESC
+     → Louis Deacon
+(+) ANSWER "Louis Deacon"
+
5 steps · reward 1.13 · recovered from error
+
+ +
+ +

Both agents have the same four tools, the same 15-step budget, and the same databases. The untrained agent wastes most of its steps without making progress. The trained agent first explores the schema, then hits an error, adapts, and solves a harder question in a third of the steps.

+ +

The Gap

+ +

Standard text-to-SQL evaluation works like this: hand the model a complete schema (all tables, all columns, all relationships) and ask it to produce one SQL query. If the query matches the gold answer, it passes. This setup rewards memorization. The model never learns to explore a schema or iterate toward a solution, so it struggles on unfamiliar databases with many tables where the full schema cannot fit in context.

+ +

SQLEnv takes a different approach. The agent progressively discovers the schema through its own actions: it starts with only table names and must call DESCRIBE, SAMPLE, and QUERY to reveal columns, types, and relationships within a fixed step budget. This is a POMDP (partially observable Markov decision process) where the agent acts under uncertainty, which makes exploration necessary and learnable.

+ +

What Analysts Actually Do

+ +

Consider the situation where you need to answer a question using data in an unfamiliar database. You probably cannot write the final query in one go. Instead, you run DESCRIBE to see what columns exist, SELECT * LIMIT 5 to scan the actual data, then build your query piece by piece, adjusting joins, fixing column names, and retrying after errors. The answer emerges from iteration.

+ +

SQLEnv captures this workflow. Four actions mirror what analysts do:

+ +
    +
  • DESCRIBE reveals column names and types for a table
    • +
  • SAMPLE previews rows to understand the data
    • +
  • QUERY executes a read-only SQL query
    • +
  • ANSWER submits a final answer
    • +
+ +

Each episode starts with a natural-language question and a list of table names. Columns, types, and relationships stay hidden until the agent discovers them through exploration. This partial observability forces strategy over pattern-matching.

+ +

A clean episode on the question "List student IDs with registered courses and their course counts":

+ +
+ +
Step 1: DESCRIBE student_course_registrations
+        → student_id INTEGER, course_id INTEGER, registration_date DATETIME
+        → reward: +0.015  ← new schema revealed
+
+Step 2: DESCRIBE students
+        → student_id INTEGER, student_details VARCHAR(255)
+        → reward: +0.015  ← second table described
+
+Step 3: QUERY SELECT T1.student_id, count(*)
+              FROM students AS T1
+              JOIN student_course_registrations AS T2
+                ON T1.student_id = T2.student_id
+              GROUP BY T1.student_id
+        → 111|1, 121|2, 131|1, 141|2, 151|1, 161|1, 171|1
+        → reward: +0.150  ← results overlap with gold answer
+
+Step 4: ANSWER [[111,1],[121,2],[131,1],[141,2],[151,1],[161,1],[171,1]]
+        → correct
+        → reward: +1.000  ← terminal: correct answer
+
+ +

Total reward: 1.180. Four steps. Exploration: 0.180, terminal: 1.000.

+ +

Built on OpenEnv

+ +

OpenEnv is a standard protocol for RL environments with a simple contract:

+ +
    +
  • reset(seed) starts a new episode and returns the initial observation
    • +
  • step(action) executes one action and returns observation, reward, and done flag
    • +
+ +

Pydantic models enforce typed contracts between agent and environment. Any environment that implements this protocol plugs into TRL, torchforge, and Unsloth without glue code. SQLEnv implements it with four actions (DESCRIBE, SAMPLE, QUERY, ANSWER):

+ +
+
method
+
action type
+
argument
+
+ +
+ +
env = SQLEnvironment(questions_path="...", db_dir="...", tokenizer=tok)
+obs = env.reset(seed=42)
+obs = env.step(SQLAction(action_type="DESCRIBE", argument="employee"))
+obs = env.step(SQLAction(action_type="QUERY",    argument="SELECT COUNT(*) FROM employee"))
+obs = env.step(SQLAction(action_type="ANSWER",   argument="10"))
+
+ +

TRL's environment_factory auto-discovers the four tool methods from the environment class for GRPO training. The same environment runs locally, in Docker on HuggingFace Spaces, or over WebSocket.

+ +

The Green Agent evaluator wraps this protocol for benchmarking:

+ +
+
evaluate(env, policy, n_episodes=50, seed=0)
+
+ +

This runs any Policy through the environment and reports success rate, average reward, and step count. Built-in RandomPolicy and OraclePolicy baselines provide lower and upper bounds (0% vs 100% accuracy, 0.25 vs 1.17 reward).

+ +

Reward Architecture

+ +

Three layers of reward signal:

+ +
+ + + + + + + + + + + + + + + + +
LayerSignalPer-step clip
L1: OperationalSuccessful execution (+0.02), new info (+0.01), repeat (-0.03), step cost (-0.02)[-0.10, 0.15]
L2: ProgressDelta from previous query result — cardinality, value overlap, numeric proximity. Positive (+) for improvement, negative (-) for regression.[-0.10, 0.15]
L3: TerminalCorrect answer: +1.0. Wrong: 0.0one-shot
+ +

Terminal correctness dominates. Maximum exploration reward across 15 steps is ~0.3, while a correct answer adds 1.0. An agent that explores but never answers always scores below one that answers correctly. Prior work on tool-using agents suggests that dense intermediate rewards are important for training small models (see TIPS, ToolRL, StepTool below). We did not ablate this by testing terminal-only reward at 0.6B parameters, but the progressive reward signal let us verify that the agent was learning the right strategic patterns: reward climbed from -0.1 to 0.5-0.7 as the agent shifted from random tool calls to describe-then-query-then-answer sequences.

+ +

The progress signal uses delta-from-previous-step: potential-based reward shaping (Ng et al., 1999). This preserves the optimal policy because the agent cannot game progress at the expense of correctness. We confirmed this empirically: cumulative progress caps (not potential-based) caused the agent to explore endlessly and never answer. Recent work validates this approach for tool-using agents. TIPS (2026) showed potential-based turn-level shaping improved multi-turn agents by 11.8% over GRPO baselines. ToolRL (2025) found fine-grained reward decomposition improved tool learning by 17%. StepTool (2024) confirmed step-grained shaping outperformed outcome-only rewards.

+ +

Training

+ +

We train Qwen3-0.6B with Group Relative Policy Optimization (GRPO). TRL's environment_factory runs the agent through SQLEnv for each rollout, comparing multiple rollouts per question to compute advantages.

+ +

SFT warmup proved critical. Per-turn SFT (347 examples, each one assistant turn) taught the model to call describe forever. Half the training examples were describe calls, so the model learned "when asked a question, call describe." When we applied a KL penalty during RL, every rollout stayed identical to this SFT behavior. The advantage between rollouts was zero, so no policy gradient could form.

+ +

Multi-turn SFT (120 full trajectories with assistant_only_loss) taught describe-then-query-then-answer as a coherent strategy. The subsequent GRPO training refined this into error recovery, answer formatting, and knowing when to stop exploring.

+ +

Two-phase curriculum:

+ + +
+GRPO Training Progress +

GRPO reward across Phase 1 (easy, beta=0.04) and Phase 2 (easy+medium, beta=0). Reward starts negative and climbs to 0.5-0.7 in Phase 1 as the agent learns describe-then-query-then-answer. Phase 2 holds at ~0.5. Peaks at 1.15 mark correctly solved episodes. 902 steps, ~4.75h on Colab L4.

+
+ +

SFT warmup takes ~1 minute (60 steps, loss drops from 1.6 to 0.08 in 2 epochs). GRPO Phase 1 runs ~2.25h, Phase 2 ~2.5h. Total pipeline: ~5 hours on a single Colab L4 (24GB VRAM), in one notebook session.

+ +

What the Agent Learned

+ +

The following behaviors emerged during training:

+ +
+ +
+
+ 🔎 + Schema Discovery +
+
"What is the total bonus in all evaluations?"
+
describe("evaluation") + → Employee_ID, Year_awarded, Bonus +query("SELECT SUM(Bonus) FROM evaluation") + → 19500.0 +answer("19500.0")
+
3 steps · reward 1.15 · correct
+
Aggregation on one table. Describe first, then write targeted SQL.
+
+ +
+
+ 🔧 + Error Recovery +
+
"Which employee received the biggest bonus?"
+
describe("employee") → Name, Age +query("...ORDER BY Salary DESC") + → Error: no such column: Salary +describe("evaluation") → Bonus +query("...JOIN...ORDER BY Bonus DESC") + → Louis Deacon +answer("Louis Deacon")
+
5 steps · reward 1.13 · correct
+
Two-table JOIN with error recovery. Wrong column, re-describe, retry.
+
+ +
+
+ 🚧 + The Ceiling +
+
"Which city has the most arriving flights?"
+
describe("AIRPORTS") + → City, AirportCode +query("SELECT CITY, COUNT(*) + FROM AIRPORTS GROUP BY CITY + ORDER BY COUNT(*) DESC LIMIT 1") + → Albany | 4 +answer("Albany")
+
3 steps · reward 0.0 · incorrect
+
Multi-hop JOIN (3+ tables). Counted airports, not flights. Beyond 0.6B.
+
+ +
+ +

The first two cards show learned behaviors: schema-first exploration and error recovery. The third shows where 0.6B saturates. We expand on these limitations and next steps below.

+ +

Evaluation (N=50 episodes, 2 independent runs)

+ +

All conditions run through SQLEnv's Green Agent evaluator: evaluate(env, policy, n_episodes, seed).

+ + + + + + + +
MethodAccuracyParse RateAvg Steps
Zero-shot0%24-28%10.8-12.4
1-shot0-2%16-17%14.0-14.8
3-shot0%19-20%13.8-14.8
GRPO (trained)~30%95-100%3.5-4.0
+ +

95-100% parse rate: the trained model produces valid tool-call JSON. The base model fails 76-83% of the time and burns its step budget repeating malformed output. ~30% accuracy from 0%: the base model cannot answer a single question even with 3 examples, but the trained model solves 12-16 out of 50 in 3-4 steps.

+ +

We trained two GRPO checkpoints: v1 (2 epochs) and v2 (4 epochs). Both scored ~30% accuracy across two evaluation runs. The variation between runs (6-8 percentage points) was larger than the difference between checkpoints, indicating that more training does not raise the ceiling. For RL alone, this indicates that the bottleneck is the model's 0.6B pretraining rather than the training budget.

+ +

Limitations at 0.6B Parameters

+ +

Three failure modes define the current ceiling:

+ + + +

RL drives accuracy from 0% to 30% but saturates at 0.6B capacity. We did not explore whether SFT on multi-table reasoning or structured thinking before JOINs could push past this ceiling in our current work. We discuss possible directions in the Next Steps section.

+ +

The Learning Space

+ +

The Green Agent evaluator brackets the learning space with two baselines:

+ + + + + + +
PolicyAccuracyAvg RewardAvg Steps
Random0%0.24715.0
GRPO (trained)~30%~0.353.5
Oracle100%1.1683.5
+ +

Random scores 0.247 by accumulating small exploration rewards across 15 steps without answering. Oracle scores 1.168 in 3.5 steps. This gap between 0.25 and 1.17 represents what a trained agent can learn. Our GRPO agent lands at ~0.35, above random but far below oracle, with room for improvement through better SFT warmup or larger models.

+ +

Technical Highlights

+ + + +

Next Steps

+ +

The environment supports two directions for improvement:

+ +

Thinking mode. The 30% ceiling comes from multi-table reasoning. The model cannot plan a three-table JOIN path before writing SQL. Qwen3's <think> blocks offer a way to reason about the join chain before writing the query. In our experiments, RL alone did not produce useful thinking: the model either emitted empty <think></think> blocks or collapsed into degenerate loops (<think>assistant<think>assistant...) that consumed ~23% of rollouts. Pure RL discovers that thinking tokens exist but not how to use them. SFT warmup with structured reasoning examples ("I need to join Documents → Templates → Ref_Template_Types through Template_ID") could bootstrap the format, then RL could refine when to think and when to skip. This is worth testing at 0.6B before concluding the ceiling requires a larger model.

+ +

Larger models. Our goal is small models that run locally, so scaling to 7B or beyond changes the deployment story. That said, a 1.7B model has more capacity to attend to DESCRIBE output and override pretrained column names. The environment and reward architecture do not depend on model size, so scaling up requires changing the training configuration rather than redesigning the environment. At some point, larger models may solve these questions with few-shot prompting alone, but the environment remains useful for training small models that need to run without API access.

+ +

Try It Yourself

+ + + +

Discussion

+ +

The format of SFT data matters more than the quantity. Per-turn SFT (347 examples) taught the model individual tool calls but not when to use them. The model called describe repeatedly because half the training examples were describe calls. Multi-turn SFT (120 full trajectories) taught the model to chain describe, query, and answer into a coherent episode. The difference was not the number of examples but whether each example showed a complete problem-solving sequence.

+ +

Transparent errors help the agent learn. When the environment returns "Error: no such column: full_name" instead of empty results, the agent can develop error-recovery strategies. Informative error messages give the RL training signal something to work with.

+ +

Dense rewards benefit from theoretical grounding. Potential-based shaping (Ng et al., 1999) guarantees the agent optimizes for the right objective. Without it, we observed agents accumulating exploration rewards instead of answering questions. Recent work supports this for tool-using agents. TIPS (2026) showed 11.8% gains from potential-based turn-level shaping. ToolRL (2025) found 17% improvement from fine-grained reward decomposition. StepTool (2024) confirmed step-grained shaping outperformed outcome-only rewards. These results suggest that principled reward design is important for multi-turn environments.

+ +

The environment is the contribution. The action space, reward function, and episode structure do not depend on the choice of model or RL algorithm. SQLEnv targets small models that need to learn database exploration through training, since larger models can often handle these tasks with few-shot prompting alone. As newer small language models become available, the environment provides a training ground for teaching them iterative reasoning.

The trained agent first explores the schema, then hits an error, adapts, and solves a harder question in a third of the steps. + +## The Gap + +Standard text-to-SQL evaluation works like this: hand the model a complete schema (all tables, all columns, all relationships) and ask it to produce one SQL query. If the query matches the gold answer, it passes. This setup rewards memorization. The model never learns to explore a schema or iterate toward a solution, so it struggles on unfamiliar databases with many tables where the full schema cannot fit in context. + +SQLEnv takes a different approach. The agent progressively discovers the schema through its own actions: it starts with only table names and must call DESCRIBE, SAMPLE, and QUERY to reveal columns, types, and relationships within a fixed step budget. This is a POMDP (partially observable Markov decision process) where the agent acts under uncertainty, which makes exploration necessary and learnable. + +## What Analysts Actually Do + +Consider the situation where you need to answer a question using data in an unfamiliar database. You probably cannot write the final query in one go. Instead, you run `DESCRIBE` to see what columns exist, `SELECT * LIMIT 5` to scan the actual data, then build your query piece by piece, adjusting joins, fixing column names, and retrying after errors. The answer emerges from iteration. + +SQLEnv captures this workflow. Four actions mirror what analysts do: + +- **DESCRIBE** reveals column names and types for a table +- **SAMPLE** previews rows to understand the data +- **QUERY** executes a read-only SQL query +- **ANSWER** submits a final answer + +Each episode starts with a natural-language question and a list of table names. Columns, types, and relationships stay hidden until the agent discovers them through exploration. This partial observability forces strategy over pattern-matching. + +A clean episode on the question *"List student IDs with registered courses and their course counts"*: + +``` +Step 1: DESCRIBE student_course_registrations + → student_id INTEGER, course_id INTEGER, registration_date DATETIME + → reward: +0.015 + +Step 2: DESCRIBE students + → student_id INTEGER, student_details VARCHAR(255) + → reward: +0.015 + +Step 3: QUERY SELECT T1.student_id, count(*) + FROM students AS T1 + JOIN student_course_registrations AS T2 + ON T1.student_id = T2.student_id + GROUP BY T1.student_id + → 111|1, 121|2, 131|1, 141|2, 151|1, 161|1, 171|1 + → reward: +0.150 + +Step 4: ANSWER [[111,1],[121,2],[131,1],[141,2],[151,1],[161,1],[171,1]] + → correct + → reward: +1.000 +``` + +Total reward: 1.180. Four steps. Exploration: 0.180, terminal: 1.000. + +## Built on OpenEnv + +[OpenEnv](https://github.com/meta-pytorch/OpenEnv) is a standard protocol for RL environments. The contract is simple: + +- `reset(seed)` starts a new episode and returns the initial observation +- `step(action)` executes one action and returns observation, reward, and done flag + +Pydantic models enforce typed contracts between agent and environment. Any environment that implements this protocol plugs into TRL, torchforge, and Unsloth without glue code. + +SQLEnv implements this protocol with four domain-specific actions: + +```python +env = SQLEnvironment(questions_path="...", db_dir="...", tokenizer=tok) +obs = env.reset(seed=42) # pick question, load DB, hide schema +obs = env.step(SQLAction(action_type="DESCRIBE", argument="employee")) +obs = env.step(SQLAction(action_type="QUERY", argument="SELECT COUNT(*) FROM employee")) +obs = env.step(SQLAction(action_type="ANSWER", argument="10")) +# obs.done=True, obs.reward=1.0 +``` + +TRL's `environment_factory` auto-discovers the four tool methods (`describe`, `sample`, `query`, `answer`) from the environment class for GRPO training. The same environment runs locally, in Docker on HuggingFace Spaces, or over WebSocket via `SQLEnvClient`. + +The Green Agent evaluator wraps this protocol for benchmarking: + +```python +evaluate(env, policy, n_episodes=50, seed=0) +``` + +This runs any `Policy` through the environment and reports success rate, average reward, and step count. Built-in `RandomPolicy` and `OraclePolicy` baselines provide lower and upper bounds (0% vs 100% accuracy, 0.25 vs 1.17 reward). + +## Reward Architecture + +Three layers of reward signal: + +| Layer | Signal | Per-step clip | +|-------|--------|---------------| +| **L1: Operational** | Successful execution (+0.02), new info (+0.01), repeat penalty (-0.03), step cost (-0.02) | [-0.10, 0.15] | +| **L2: Progress** | Delta from previous query result — cardinality, value overlap, numeric proximity | [-0.10, 0.15] | +| **L3: Terminal** | Correct answer: +1.0. Wrong: 0.0 | one-shot | + +Terminal correctness dominates. Maximum exploration reward across 15 steps is ~0.3, while a correct answer adds 1.0. An agent that explores but never answers always scores below one that answers correctly. Prior work on tool-using agents suggests that dense intermediate rewards are important for training small models (see TIPS, ToolRL, StepTool below). We did not ablate this by testing terminal-only reward at 0.6B parameters, but the progressive reward signal let us verify that the agent was learning the right strategic patterns: reward climbed from -0.1 to 0.5-0.7 as the agent shifted from random tool calls to describe-then-query-then-answer sequences. + +The progress signal uses delta-from-previous-step, a form of potential-based reward shaping ([Ng et al., 1999](https://people.eecs.berkeley.edu/~pabbeel/cs287-fa09/readings/NgHaradaRussell-shaping-ICML1999.pdf)). This preserves the optimal policy because the agent cannot game progress at the expense of correctness. We confirmed this empirically: cumulative progress caps (not potential-based) caused the agent to explore endlessly and never answer. Recent work validates this approach for tool-using agents. [TIPS](https://arxiv.org/abs/2603.22293) (2026) showed potential-based turn-level shaping improved multi-turn agents by 11.8% over GRPO baselines. [ToolRL](https://arxiv.org/html/2504.13958v1) (2025) found fine-grained reward decomposition improved tool learning by 17%. [StepTool](https://arxiv.org/abs/2410.07745) (2024) confirmed step-grained shaping outperformed outcome-only rewards. + +## Training + +We train Qwen3-0.6B with Group Relative Policy Optimization (GRPO). TRL's `environment_factory` runs the agent through SQLEnv for each rollout, comparing multiple rollouts per question to compute advantages. + +SFT warmup proved critical. Per-turn SFT (347 examples, each one assistant turn) taught the model to call describe forever. Half the training examples were describe calls, so the model learned "when asked a question, call describe." When we applied a KL penalty during RL, every rollout stayed identical to this SFT behavior. The advantage between rollouts was zero, so no policy gradient could form. + +Multi-turn SFT (120 full trajectories with `assistant_only_loss`) taught describe-then-query-then-answer as a coherent strategy. The subsequent GRPO training refined this into error recovery, answer formatting, and knowing when to stop exploring. + +Two-phase curriculum: +- **Phase 1**: Easy questions (single-table), KL penalty (beta=0.04) to keep the policy close to SFT initialization while allowing exploration. Reward climbs from -0.1 to 0.5-0.7 over 400 steps. +- **Phase 2**: Easy + medium (multi-table JOINs), KL removed (beta=0) so the agent can deviate further from SFT and discover new strategies.

The base model fails 76-83% of the time and burns its step budget repeating malformed output. **~30% accuracy from 0%**: the base model cannot answer a single question even with 3 examples, but the trained model solves 12-16 out of 50 in 3-4 steps. + +We trained two GRPO checkpoints: v1 (2 epochs) and v2 (4 epochs). Both scored ~30% accuracy across two evaluation runs. The variation between runs (6-8 percentage points) was larger than the difference between checkpoints, indicating that more training does not raise the ceiling. For RL alone, this indicates that the bottleneck is the model's 0.6B pretraining rather than the training budget. + +## Limitations at 0.6B Parameters + +Three failure modes define the current ceiling: + +- **Column name hallucination.** The model reads `FullName` from DESCRIBE but writes `full_name` in SQL, or reads `Horsepower` and writes `HorsepowerDESC` (missing space). Pretraining biases override the schema that the model just observed in context. +- **FK chain reasoning.** The model handles single-table queries well but fails on three-table JOINs such as Documents → Templates → Ref_Template_Types. It cannot chain foreign keys through intermediate tables. +- **More RL does not help.** Extended training (v2: 4 total epochs) produced identical accuracy. This indicates the ceiling comes from pretraining knowledge rather than training budget. + +RL drives accuracy from 0% to 30% but saturates at 0.6B capacity. We did not explore whether SFT on multi-table reasoning or structured thinking before JOINs could push past this ceiling in our current work. We discuss possible directions in the Next Steps section. + +## The Learning Space + +The Green Agent evaluator brackets the learning space with two baselines: + +| Policy | Accuracy | Avg Reward | Avg Steps | +|--------|----------|------------|-----------| +| Random | 0% | 0.247 | 15.0 | +| **GRPO (trained)** | **~30%** | **~0.35** | **3.5** | +| Oracle | 100% | 1.168 | 3.5 | + +Random scores 0.247 by accumulating small exploration rewards across 15 steps without answering. Oracle scores 1.168 in 3.5 steps. This gap between 0.25 and 1.17 represents what a trained agent can learn. Our GRPO agent lands at ~0.35, above random but far below oracle, with room for improvement through better SFT warmup or larger models. + +## Technical Highlights + +- **676 questions** (473 train / 203 eval) across 10 Spider databases with difficulty labels +- **Typed models** with Pydantic: every action, observation, and state is explicit and debuggable +- **Read-only SQL** via SQLite `mode=ro`, where the database engine enforces safety rather than regex +- **Potential-based reward shaping** (Ng et al., 1999) that provably preserves the optimal policy +- **TRL environment_factory** integration for standard GRPO training without a custom loop +- **Green Agent evaluator** with `Policy` protocol, `evaluate()` harness, and `RandomPolicy`/`OraclePolicy` baselines + +## Next Steps + +The environment supports two directions for improvement: + +**Thinking mode.** The 30% ceiling comes from multi-table reasoning. The model cannot plan a three-table JOIN path before writing SQL. Qwen3's `` blocks offer a way to reason about the join chain before writing the query. In our experiments, RL alone did not produce useful thinking: the model either emitted empty `` blocks or collapsed into degenerate loops (`assistantassistant...`) that consumed ~23% of rollouts. Pure RL discovers that thinking tokens exist but not how to use them. SFT warmup with structured reasoning examples ("I need to join Documents → Templates → Ref_Template_Types through Template_ID") could bootstrap the format, then RL could refine when to think and when to skip. This is worth testing at 0.6B before concluding the ceiling requires a larger model. + +**Larger models.** Our goal is small models that run locally, so scaling to 7B or beyond changes the deployment story. That said, a 1.7B model has more capacity to attend to DESCRIBE output and override pretrained column names. The environment and reward architecture do not depend on model size, so scaling up requires changing the training configuration rather than redesigning the environment. At some point, larger models may solve these questions with few-shot prompting alone, but the environment remains useful for training small models that need to run without API access. + +## Try It Yourself + +- **Training notebook**: `notebooks/train_grpo.ipynb` runs the full SFT + GRPO pipeline on Colab L4 in ~7 hours +- **Comparison notebook**: `notebooks/compare_methods.ipynb` evaluates base vs trained models side by side +- **Showcase notebook**: `notebooks/showcase_sqlenv.ipynb` lets you explore the environment, run episodes, and see what tools and rewards are available +- **GitHub**: full source, architecture docs, and training artifacts + +## Discussion + +**The format of SFT data matters more than the quantity.** Per-turn SFT (347 examples) taught the model individual tool calls but not when to use them. The model called describe repeatedly because half the training examples were describe calls. Multi-turn SFT (120 full trajectories) taught the model to chain describe, query, and answer into a coherent episode. The difference was not the number of examples but whether each example showed a complete problem-solving sequence. + +**Transparent errors help the agent learn.** When the environment returns `"Error: no such column: full_name"` instead of empty results, the agent can develop error-recovery strategies. Informative error messages give the RL training signal something to work with. + +**Dense rewards benefit from theoretical grounding.** Potential-based shaping (Ng et al., 1999) guarantees the agent optimizes for the right objective. Without it, we observed agents accumulating exploration rewards instead of answering questions. Recent work supports this for tool-using agents. TIPS (2026) showed 11.8% gains from potential-based turn-level shaping. ToolRL (2025) found 17% improvement from fine-grained reward decomposition. StepTool (2024) confirmed step-grained shaping outperformed outcome-only rewards. These results suggest that principled reward design is important for multi-turn environments. + +**The environment is the contribution.** The action space, reward function, and episode structure do not depend on the choice of model or RL algorithm. SQLEnv targets small models that need to learn database exploration through training, since larger models can often handle these tasks with few-shot prompting alone. As newer small language models become available, the environment provides a training ground for teaching them iterative reasoning. diff --git a/docs/blog-post.md b/docs/blog-post.md new file mode 100644 index 0000000000000000000000000000000000000000..8a4b3edbd750aebf643016261fdc3bf07ffb5ce1 --- /dev/null +++ b/docs/blog-post.md @@ -0,0 +1,118 @@ +# SQLEnv: Teaching Small Models to Explore Databases Like Analysts + +## What Analysts Do That One-Shot LLMs Miss + +A data analyst opens a new database. She doesn't write the final query first.

The answer emerges from a process, not a guess. + +Most text-to-SQL systems skip this process entirely. They take a question and a schema, produce one SQL query, and hope it's right.

High accuracy on these benchmarks doesn't mean the model can handle an unfamiliar schema. It means the model memorized patterns from training data that happen to match the test set. + +The gap shows up immediately in production. Schemas change. Column names don't match expectations. Tables have unexpected relationships. A model that can't recover from its first wrong guess is brittle in exactly the situations where SQL competence matters most. + +The deeper problem: these benchmarks grade the final answer and ignore the process. An agent that explores the schema, discovers a mistake, and corrects itself gets the same score as one that guesses right on the first try — and no credit at all when the guess fails.

But the interesting behavior is what happens when things go wrong. + +On a harder question — *"Which employee received the biggest bonus?"* — the agent tries `SELECT Name FROM employee ORDER BY Salary DESC LIMIT 1`, gets `no such column: Salary`, calls `describe("evaluation")` to find the Bonus column, then writes the correct JOIN. The error recovery is learned behavior, not hard-coded. + +## Reward Architecture + +The environment provides three layers of reward signal: + +**Operational feedback** on every step: did the SQL execute (+0.02) or error? Is this a new query (+0.01) or a repeat (-0.01)? + +**Progress signal** on queries: how close are the results to the correct answer? Measured by value overlap and result cardinality, shaped as delta-from-previous-step. This form is potential-based (Ng et al., 1999), which provably preserves the optimal policy — the agent can't game progress rewards at the expense of correctness. + +**Terminal reward** for the answer: +1.0 for correct, 0.0 for wrong. + +Terminal correctness dominates by design. The maximum exploration reward across all steps is roughly 0.3; a correct answer is worth 1.0.

We generate 120 multi-turn trajectories showing the full describe→query→answer workflow, trained with `assistant_only_loss` so the model learns from its own actions, not the environment's responses. Without this, GRPO has no coherent policy to improve — the agent never learns to call tools in sequence. + +## What We Observed + +Across nine training runs on Qwen3-0.6B, three findings stand out. + +**The environment produces clear learning signal.** Phase 1 reward climbs from near-zero to 0.5–0.7 within 400 steps. The model learns to describe tables before querying, format answers correctly (comma-separated lists, pipe-delimited rows), recover from SQL errors by re-describing tables, and submit `[]` for genuinely empty results. These are strategic behaviors that emerge from reward signal, not from hard-coded rules. + +**The model hits a capacity ceiling on medium questions.** Multi-table JOIN queries — the kind requiring foreign-key chain reasoning across 3+ tables — don't improve with more training. We ran extended training (v2: 4 total epochs across both phases) and the reward curve stayed flat. The dominant failure mode is column name hallucination: the model reads the schema correctly via DESCRIBE, then writes SQL using pretrained column names that don't match. A 0.6B model can't override pretraining biases through RL reward signal alone. + +**Thinking mode helps error recovery but doesn't raise the ceiling.** With Qwen3's thinking mode enabled, the model reasons through SQL errors in `` blocks — noticing column name mismatches, adjusting join paths. Easy-question accuracy stays the same, but error recovery becomes more deliberate. A new failure mode emerges: ~23% of rollouts degenerate into unclosed `` loops that consume the entire token budget. The fix is straightforward (add SFT examples with proper think blocks), but it reveals how small models struggle with structural token management. + +### Training metrics (Run 9, Qwen3-0.6B) + +| Phase | Steps | Questions | Reward range | Mean reward | +|-------|-------|-----------|-------------|-------------| +| Phase 1 (easy, β=0.04) | 870 | 435 | 0.01–1.15 | ~0.5 | +| Phase 2 (easy+medium, β=0.0) | 934 | 467 | 0.01–1.15 | ~0.5 | + +Parse rate: >98% (model produces valid tool-call JSON).

Our v1/v2 runs used +this path. + +**One nuance (intentional design):** `SQLEnvTRL.__init__` instantiates a +**local in-process `SQLEnvironment`**, not a WebSocket client to +`https://hjerpe-sql-env.hf.space`. Reasons: + +- Training opens N parallel sessions (one per generation). The hosted Space + defaults to 1 concurrent session — see `SUPPORTS_CONCURRENT_SESSIONS` in + the TRL↔OpenEnv docs. +- Local is faster, no network hops, no rate limits. +- The hosted Space is for judges (clicking `/web`) and external users + consuming the env via pip/Docker. Training correctly bypasses it. + +**Implication for the blog:** you can claim "TRL-native integration via +`environment_factory`" factually. It's already true and the notebook proves it. + +**What's still on the post-launch list** is the Space-side concurrency config +(item 8), not the adapter.

SFT Null-Param Injection (ROOT CAUSE of first collapse) +**Problem**: Qwen3's `apply_chat_template` expands dict arguments to include ALL parameter names from ALL tools with null values. SFT trained model to always generate `{"sql": null, "table_name": "X", "value": null}`. +**Fix**: Pass arguments as JSON strings (`json.dumps({"table_name": table})`) instead of dicts. Tokenizer uses strings verbatim. + +### 2. SFT Answer Formatting +**Problem**: Gold answers were Python literals (`['a', 'b']`, `[[1, 'amc']]`). Model learned wrong format. +**Fix**: `_format_answer_for_model()` converts to human-readable: comma-separated lists, pipe-separated table rows. + +### 3. Empty Tool Responses +**Problem**: TRL adapter returned `observation.result` (empty on SQL errors), hiding errors from model. +**Fix**: `_result_or_error()` falls back to `observation.error` so model sees "Error: SQL error: ...". + +### 4. Post-Episode Penalty +**Problem**: Model continues calling tools after answering, wasting steps with no signal. +**Fix**: `_POST_EPISODE_PENALTY = -0.1` applied in all 4 tool methods when `self._done` is True. + +### 5. Answer Stripping +**Problem**: Model wraps answers in quotes, code fences, "Answer:" prefix. +**Fix**: `_strip_answer_wrapping()` in verifier preprocesses predicted answers. + +### 6. Per-Turn SFT → Multi-Turn SFT (ROOT CAUSE of Run 5 stall) +**Problem**: SFT generated one example per assistant turn (347 examples, ~50% describe calls). Model over-learned "call describe" and never practiced query→answer. During GRPO with KL penalty, model stayed anchored to this single-turn policy. +**Fix**: Generate one full multi-turn example per question (100 examples, each containing describe→query→answer). Enable `assistant_only_loss` via Qwen3 template patch so loss is on assistant turns only. +**Key detail**: Qwen3's chat template lacks `{% generation %}` tags required by TRL for `assistant_only_loss`. Patch the template before SFT, restore original before GRPO (TRL does exact-match template checks in `add_response_schema()` and `get_training_chat_template()`). + +### 7. Removed Arrow-Notation Few-Shot Examples +**Problem**: System prompt contained few-shot examples using arrow notation (`→ describe(table_name="X")`) while the model must produce `{"name":"describe","arguments":...}` JSON. Two competing formats for a 1.7B model. +**Fix**: Removed `_FEW_SHOT_BLOCK` from system prompt. The textual "Strategy" section is sufficient. + +### 8. KL Penalty + Curriculum +**Problem**: GRPO drifted policy away from SFT, causing `` instead of ``. +**Fix**: `beta=0.04` KL penalty + easy-first curriculum (phase 1: easy only, phase 2: easy+medium). With multi-turn SFT, beta=0.04 no longer blocks exploration. + +### 9. OOM with Reference Model +**Problem**: `beta>0` loads reference model copy, doubling memory on L4. +**Fix**: Reduced `num_generations` 6→4, `max_new_tokens` 1024→512 for phase 1. Phase 2 drops beta=0 and uses 1024 tokens. + +### 10. generation_batch_size Divisibility +**Problem**: `generation_batch_size` (default 8) not divisible by `num_generations` (6). +**Fix**: Set `generation_batch_size=config.num_generations` in notebook_pipeline. + +## Discovered Issues (not yet fixed) + +### CTE (WITH clause) rejected by environment +**Problem**: `sql_environment.py` SQL validation only allows queries starting with `SELECT`. The model discovers CTEs during GRPO (`WITH dogs AS (...) SELECT ...`), gets `"Error: Only SELECT queries are allowed. Got: WITH"`, wastes a step recovering. +**Impact**: Burns 1-2 steps on error recovery, reducing reward. Teaches model to avoid CTEs even though they're valid read-only SQL. +**Root cause**: Hard-coded prefix check. The DB is already opened with `mode=ro`, so SQLite itself would reject writes. +**Fix**: Allow `WITH` as a valid query prefix, or remove the prefix check entirely and rely on `mode=ro`. + +### Post-episode repetition +**Problem**: Model keeps calling tools after episode ends (gets `{'error': 'Episode is over'}`). The -0.1 penalty exists but model still does 3-5 extra calls. +**Possible fixes**: Increase penalty, or the model may learn to stop as GRPO training progresses. + +### HF_SUFFIX naming bug (FIXED) +**Problem**: `HF_SUFFIX` is concatenated directly onto `grpo` without auto-prepending a dash. Setting `HF_SUFFIX="no-no-thinking"` produces `sqlenv-qwen3-1.7b-grpono-no-thinking` instead of the intended `sqlenv-qwen3-1.7b-grpo-no-no-thinking`. The `grpono-no-thinking` checkpoint on HF Hub was manually renamed via HF UI after push. +**Root cause**: Format string `f"sqlenv-{_model_short}-grpo{HF_SUFFIX}"` expects the user to include a leading dash. +**Fix**: Auto-prepend dash + strip existing prefixes from checkpoint names. When resuming from `hjerpe/sqlenv-qwen3-0.6b-grpo`, the old code produced `sqlenv-sqlenv-qwen3-0.6b-grpo-grpo-v2` (double prefix). Now strips `sqlenv-` and `-grpo*` from `_model_short` before rebuilding the name. +**Files**: `notebooks/train_grpo.ipynb` save cell. + +### Save cell uses Phase 1 config for output_dir +**Problem**: `model.save_pretrained(config.output_dir)` uses Phase 1's `config`, not Phase 2's `config2`.

More negative values than v1 Phase 1 — expected since starting from trained checkpoint, less to learn. + - Rewards: sawtooth 0.01-1.15. Easy questions solved reliably (describe→query→answer in 3 calls). Medium questions from mixed batches still fail. + - Model behavior: solid tool-call format, comma-separated lists, pipe-delimited rows. No format collapse. + - Step 300: Degenerate SQL — `ORDER BY HorsepowerDESC` (missing space), repeated 3 times. Token budget consumed. + - Step 560: Degenerate completion — output "icher Consulting Solution" (truncated gibberish). Reward 0.00. One-off. +- **Phase 2** (467 easy+medium, beta=0.0, 1024 tokens, ~3h50m, 934 steps): + - Loss: oscillates -0.13 to +0.12, trend more negative than Phase 1 — policy sharpens on known patterns without KL regularization. + - Rewards: same sawtooth 0.01-1.15 as Phase 1, no upward trend. Mean ~0.5. + - **Successes (medium)**: Step 140 — JOINed evaluation→employee for MAX(bonus), found "Louis Deacon" (1.13 reward). Step 750 — subquery `COUNT(*) > (SELECT ... ORDER BY Horsepower DESC LIMIT 1)`, answered "39" correctly. + - **Failures (medium)**: Step 20 — hallucinated `make_id`, `full_name` columns, budget exhausted after 8+ tool calls. Step 50 — invented `Course_Attendance` table, cascading errors. Step 530 — tried `Bred`, `Breed` before finding `Breeds`, then queried wrong column. + - **Persistent pattern**: Model describes tables correctly but writes SQL with wrong column names from pretraining knowledge (e.g., `full_name` instead of `FullName`, `country.name` when table is `singer` with `Country` column). + - Final reward: 0.048 (last step was incorrect) +- **Charts**: Reward Trend (Phase 1→2) shows flat continuation — no improvement from adding medium questions. Loss in Phase 2 oscillates around 0, with spikes to -0.13 (GRPO reinforcing already-known easy patterns). +- **Conclusion**: v2 confirms v1 findings. The 0.6B model's accuracy ceiling is set by pretraining SQL knowledge, not RL training budget. More epochs don't help medium questions. Next interventions: (1) more SFT on multi-table JOINs with correct column names, (2) larger model (1.7B), or (3) increase step budget to let model iterate. + +### Eval Format Fix (F011 comparison notebook) +- **Date**: 2026-04-10 +- **Problem**: `compare_methods.ipynb` eval fed models a different message format than TRL training: + 1. Tool results posted as `role: "user"` — training uses `role: "tool"` (Qwen3 renders as `` wrapper) + 2.

Highest priority — v2 proved more RL epochs don't help without this. +- **Increase model size**: Switch from 0.6B to 1.7B. Larger model may override pretrained column name biases from schema context. + +### OOM prevention for next thinking-mode run: +The Run 8 Phase 2 crash at step 182/467 was likely OOM. Root causes and mitigations: + +1. **`max_new_tokens=1280` is too high for L4 with thinking** — medium questions trigger long `` blocks (Step 50 reasoning about `>1` vs `>=1`, Step 120 about breed/size format, Step 130 about `T1.distinct_city` column mismatch). Reduce to **1024** for Phase 2. +2. **`num_generations=4` compounds the problem** — each generation runs inference independently, so 4 rollouts × 1280 tokens = 5120 tokens of peak generation memory. Reduce to **3 generations** for thinking-mode Phase 2. The `generation_batch_size` must also be updated to match. +3. **The `assistant` degenerate loop inflates effective token usage** — a rollout that enters the loop consumes the full `max_new_tokens` budget producing garbage. Fixing this loop via SFT (adding 5-10 examples with proper `reasoning` blocks) would reduce average token consumption significantly, making OOM less likely even at higher token limits. +4. **Phase 2 has no KL reference model (beta=0)** — so memory is only model + generation buffers. The OOM is purely from generation length, not model copies. + +**Recommended config for next thinking-mode run (Phase 2):** +```python +config2 = replace(config, + beta=0.0, + max_new_tokens=1024, # was 1280 + num_generations=3, # was 4 + enable_thinking=True, +) +``` +Also set `generation_batch_size=3` in `notebook_pipeline.py` (it must equal `num_generations`). + +## Historical: Status after Run 6 + +### Architecture decisions to preserve: +- Multi-turn SFT with `assistant_only_loss` — critical over per-turn +- Qwen3 template patch (`{% generation %}` tags) for SFT, restore original before GRPO +- SFT args as JSON strings (not dicts) — critical for Qwen3 +- Phase 1 (easy, KL) → Phase 2 (easy+medium, no KL) +- DB opened with `mode=ro` — safety enforced by SQLite, not regex + +## File Map + +| File | What changed | +|------|-------------| +| `scripts/generate_sft_data.py` | Multi-turn trajectories, JSON string args, answer formatting | +| `scripts/inspect_sft_data.py` | SFT data stats + tokenizer-rendered inspection | +| `training/trl_adapter.py` | Post-episode penalty (-0.3), error surfacing, `_result_or_error` | +| `training/config.py` | Added beta field (KL penalty) | +| `training/notebook_pipeline.py` | generation_batch_size, beta passthrough | +| `server/verifier.py` | `_strip_answer_wrapping` preprocessing | +| `server/sql_environment.py` | SQL validation allows SELECT and WITH | +| `notebooks/train_grpo.ipynb` | Multi-turn SFT, assistant_only_loss, template patch/restore, HF_SUFFIX | + +## Key Learnings + +1. **Qwen3's apply_chat_template expands dict args** — always use JSON strings for SFT tool_call arguments. +2. **Multi-turn SFT is critical for agentic GRPO** — per-turn examples teach one action; the model never learns the full workflow. Full trajectory SFT with `assistant_only_loss` teaches describe→query→answer as a coherent strategy. +3. **Qwen3 template lacks {% generation %} tags** — patch before SFT for `assistant_only_loss`, restore before GRPO. TRL's `add_response_schema()` and `get_training_chat_template()` do exact string equality on the template. +4. **Don't show competing formats to small models** — arrow-notation few-shot examples confused the model when it needed to produce `` JSON. +5. **KL penalty effectiveness depends on SFT quality** — beta=0.04 was "too high" only because the SFT policy was single-turn. With multi-turn SFT, the same beta works fine. +6. **Reference model doubles memory** — plan for this when using KL penalty on L4. +7. **Let the SQL engine enforce safety, not regex** — hard-coded `SELECT`-only prefix check blocks valid read-only SQL (CTEs). The DB is already `mode=ro`. +8. **Render training data through the actual tokenizer** — inspect scripts that reformat JSON are fragile. The ground truth is `apply_chat_template` output from the same tokenizer instance used for training. +9. **Error loops are a 1.7B capacity limit** — the model repeats failing queries verbatim because `` is suppressed and it can't reason about the error. Enabling thinking mode may help. +10. **Post-episode penalty of -0.1 is too weak** — model still makes 3-5 extra calls. Increased to -0.3. +11. **Repeat penalty works but doesn't fix root cause** — the −0.2 penalty fires correctly on exact-match repeated tool calls, but the model's real problem is pretrained column-name hallucination, not repetition per se. The model varies its queries enough to avoid exact repeats while still failing on the same conceptual error. +12. **Phase 2 (medium) doesn't improve over Phase 1 (easy)** — reward plateau at ~0.5 suggests the model needs more SFT coverage on multi-table JOINs, not just more GRPO steps. RL can't teach FK chain reasoning that isn't in the initial policy. +13. **Thinking mode helps error recovery but doesn't improve overall accuracy** — the model uses `` blocks to reason about SQL errors (column name mismatches, table structure), leading to correct retries. But accuracy on easy questions is similar to no-think Run 7. The benefit is qualitative (better error recovery) not quantitative (higher reward). +14. **`assistant` degenerate loop is a new failure mode** — ~23% of thinking-mode steps degenerate into `assistantassistant...` repeating until token limit. The model fails to produce `` and enters a repetitive pattern. This is the thinking-mode equivalent of Run 7's post-episode repetition. Fix: add SFT examples with proper `reasoning` blocks. +15. **Empty `` blocks are good** — the model learns to skip thinking on easy questions, preserving tokens for tool calls. This is emergent behavior from GRPO reward signal (thinking wastes tokens → lower reward on easy questions). +16. **1280 max_new_tokens is too aggressive for thinking mode on L4** — Phase 2 crashed at step 182/467, likely OOM. The longer `` blocks in Phase 2 (medium questions trigger more reasoning) push memory past L4's 24GB. Use 1024 max_new_tokens for thinking-mode Phase 2. +17. **Public methods on environment_factory become TRL tools** — TRL introspects all public methods for JSON schema generation. The `configure()` classmethod caused a `DocstringParsingException`. Keep configuration methods private (`_configure`). +18. **Continued training from checkpoint doesn't unlock medium questions** — v2 ran 2 more epochs of Phase 1 + Phase 2 from v1's final checkpoint. Reward stayed flat at ~0.5 mean. The model reliably solves easy single-table queries but can't learn multi-table FK chain reasoning from RL alone. The policy needs SFT coverage on the patterns it can't discover through trial-and-error. +19. **Column name hallucination is the dominant error mode** — the model describes tables correctly (seeing `FullName: TEXT`) then writes `SELECT full_name` or `SELECT Maker, FullName FROM car_makers ORDER BY MakerDESC LIMIT 1` (missing space). This is pretrained SQLese overriding the schema information the model just read. A 0.6B model can't override pretraining biases through RL reward signal alone. +20. **Eval must exactly match TRL's message format** — `role:"tool"` for env results (not `role:"user"`), structured `tool_calls` dicts for assistant turns (not raw `` text in content), question+table_hint concatenated without separator (TRL appends `reset()` return to last user message). Qwen3 renders `role:"tool"` as `<|im_start|>user\n...` — looks like a user message but is structurally different. Getting this wrong caused 0% accuracy across all conditions; fixing it recovered 10-50% on base model. +21. **Incorrect answer reward of 0.0 creates an avoid-answering incentive** — exploration steps accumulate ~0.05-0.15 reward. Calling `answer(wrong)` gives 0.0 and ends the episode, so total reward (~0.05) can be lower than not answering and exploring until budget (~0.10). The model may learn to write prose instead of calling `answer()` when uncertain. PRS (Progressive Reward Shaping, arxiv 2512.07478) addresses this with a small format-compliance reward for completing the tool pipeline regardless of correctness. +22. **Continued training trades guessing for abstention** — v2 outputs "Task complete." instead of calling `answer()` on hard questions — a form of calibrated uncertainty. v1 guesses more but gets fewer right per attempt. The 0.0 incorrect-answer reward (learning #21) drives this: v2 internalized that guessing wrong is worse than not answering. +23. **v1 and v2 are statistically indistinguishable at N=50** — across two runs, v1 scored 28% then 30%, v2 scored 32% then 24%. The ~6-8pp run-to-run variation exceeds the checkpoint difference. v2's abstention behavior (learning #22) adds variance: on borderline questions, whether v2 guesses or outputs "Task complete." varies by run. For reporting, use "~30% accuracy" for both checkpoints. N=200+ would be needed to detect a real 4pp difference with 80% power. diff --git a/docs/exploration/rl-vs-icl-research.md b/docs/exploration/rl-vs-icl-research.md new file mode 100644 index 0000000000000000000000000000000000000000..b9e16598943195401f32bec5aa7d33017195949c --- /dev/null +++ b/docs/exploration/rl-vs-icl-research.md @@ -0,0 +1,157 @@ +--- +title: RL vs In-Context Learning for Small Model SQL Agents +description: Research synthesis on when GRPO training adds value over pure prompting with in-context learning for sub-2B parameter models +doc_type: exploration +--- + +# RL vs In-Context Learning for Small Model SQL Agents + +Exploration doc for F011 (Prompting Baseline Notebook). + +## Context + +We train Qwen3-0.6B/1.7B to explore SQL databases using multi-turn tool +calls (describe, query, answer).

Results are always truncated/summarized (max N rows as formatted text). This is intentional — the agent sees "what a real analyst would see", not the full database. This makes the environment a POMDP, which is appropriate for the task and beneficial for learning dynamics (see Section 3). + +### 2.3 State + +Uses the core `State` class from OpenEnv (`episode_id` + `step_count`). No custom state needed for MVP. + +### 2.4 Action Space + +| Action | Argument | Effect | Cost | +|---|---|---|---| +| `DESCRIBE` | table_name | Returns column names, types, row count | 1 step | +| `SAMPLE` | table_name | Returns 5 random rows (formatted text) | 1 step | +| `QUERY` | sql_string | Executes SQL, returns truncated results (max 20 rows) | 1 step | +| `ANSWER` | value | Submits final answer, ends episode | 0 steps (terminal) | + +**Step budget**: 15 steps per episode (configurable). This is enough for 2-3 exploration actions + 3-5 query attempts + answer. Keeps episodes short enough for efficient training. + +**Query sandboxing**: All SQL runs in a read-only SQLite connection with a statement timeout (5 seconds). Only SELECT statements allowed.

The agent must actively DESCRIBE tables to learn the schema. This is a deliberate design choice — it creates an exploration incentive and mirrors real-world "I have a database, what's in it?" workflows. + +--- + +## 3. Reward Architecture + +The reward research (SQL-TRAIL, PaVeRL-SQL, QueryGym, Graph-Reward-SQL) converges on one principle: **reward improvement during exploration, but make correctness dominate at termination.** + +Our reward has 3 layers. The total episode reward is: + +``` +R_episode = R_terminal + sum(R_step_i) where sum(R_step_i) is capped at 0.5 +``` + +### 3.1 Layer 1 — Operational Validity (every step, no gold reference needed) + +These signals reward "being able to operate the tool" without referencing the gold answer. + +| Signal | Value | When | +|---|---|---| +| `r_exec_ok` | +0.02 | A QUERY executes without error | +| `r_new_info` | +0.01 | Action reveals new info (new table described, new column seen). Capped at 0.10 per episode | +| `r_repeat` | -0.01 | Exact same SQL run again (hash match), or exact same DESCRIBE/SAMPLE repeated | +| `r_cost` | -0.005 | Every step (small constant, keeps trajectories short) | + +**Design rationale**: Prefer small positive signals + "no reward" over heavy negative penalties. Strong negatives make agents risk-averse and destabilize training (PaVeRL-SQL). The step cost is tiny — just enough to prefer shorter trajectories when everything else is equal. + +### 3.2 Layer 2 — Progress-to-Target (QUERY steps only, oracle-based but coarsened) + +After each QUERY, we compute how close the query result is to the gold answer, then reward only *improvement* over the best-so-far. + +**Progress metric** (depends on answer type): + +| Answer Type | Progress Computation | +|---|---| +| **Integer/Count** | `1 - min(1, abs(pred - gold) / max(1, abs(gold)))` | +| **Float/Average** | Same as integer but with tolerance (within 1% = 1.0) | +| **String/Name** | Exact match = 1.0, else 0.0 (too fragile to partially score) | +| **List/Set** | `Jaccard(pred_set, gold_set)` — set overlap | +| **Table** | `0.5 * column_overlap + 0.5 * row_sample_overlap` | + +**Coarsening**: To prevent reward leakage (agent hill-climbing on the reward signal instead of reasoning), we bin progress into 5 levels: {0, 0.25, 0.5, 0.75, 1.0}. + +**Improvement-only reward**: +```python +progress_binned = bin_to_nearest([0, 0.25, 0.5, 0.75, 1.0], progress_raw) +r_progress = max(0, progress_binned - best_progress_so_far) * 0.15 +best_progress_so_far = max(best_progress_so_far, progress_binned) +``` + +This prevents agents from "farming" reward by oscillating between good and bad queries. + +### 3.3 Layer 3 — Terminal Correctness (ANSWER action only) + +| Condition | Reward | +|---|---| +| Answer matches gold (type-appropriate comparison) | +1.0 | +| Answer does not match | 0.0 | +| Episode times out (budget exhausted, no ANSWER) | 0.0 | + +Terminal correctness is always the dominant signal. With the cap on stepwise rewards (0.5 max), a correct answer is always worth at least 2x the maximum exploration reward. + +### 3.4 Total Reward Formula + +``` +R_episode = 1.0 * R_correct + clamp(sum(r_exec_ok + r_new_info + r_repeat + r_cost + r_progress), -0.2, 0.5) +``` + +The negative clamp at -0.2 prevents catastrophic negative episodes from destabilizing training. + +### 3.5 How This Maps to TRL's GRPOTrainer + +Following the Wordle GRPO tutorial pattern, we expose reward components as separate `reward_funcs`: + +```python +# In the training script +trainer = GRPOTrainer( + model=model_name, + processing_class=tokenizer, + reward_funcs=[ + reward_correctness, # Terminal: 0.0 or 1.0 + reward_progress, # Cumulative progress improvement (0 to 0.15) + reward_operational, # Sum of exec_ok, new_info, repeat, cost signals + ], + train_dataset=dataset, + args=grpo_config, + rollout_func=rollout_func, +) +``` + +The `rollout_func` runs a full episode against the SQLEnv server (via WebSocket), collects the observation stream, and computes per-component rewards. This lets TRL handle the weighting/normalization. + +### 3.6 Anti-Gaming Measures + +| Risk | Mitigation | +|---|---| +| Agent hill-climbs on progress signal to infer gold answer | Coarsen progress to 5 bins; step rewards are small vs. terminal | +| Agent DESCRIBEs everything to harvest `r_new_info` | Cap `r_new_info` at 0.10 per episode | +| Agent submits random answers hoping for partial credit | No partial credit on ANSWER — binary correctness only | +| Agent runs many queries to accumulate `r_exec_ok` | Step cost + budget limit make this net-negative after ~10 queries | +| Agent repeats identical queries | Hash-based repeat detection, penalty applied | + +--- + +## 4. Question Sourcing & Verification + +### 4.1 MVP: Spider Subset + +**Why Spider**: Most-studied text-to-SQL benchmark, gold SQL available for all questions, existing tooling for test suite generation, clean SQLite databases included, well-understood difficulty levels. + +**MVP question set**: 50-100 questions from Spider's dev set, selected to cover: +- Simple (SELECT/WHERE/COUNT): ~40% +- Medium (JOIN/GROUP BY): ~40% +- Hard (subqueries/HAVING/multi-step): ~20% + +**Answer types to support in MVP**: +- Integer (counts, sums) +- Float (averages — with 1% tolerance) +- String (single value lookups) +- List (top-k results — order-insensitive set comparison) + +### 4.2 Answer Verification + +```python +def verify_answer(predicted, gold, answer_type: str) -> bool: + match answer_type: + case "integer": + return int(predicted) == int(gold) + case "float": + return abs(float(predicted) - float(gold)) / max(1, abs(float(gold))) < 0.01 + case "string": + return str(predicted).strip().lower() == str(gold).strip().lower() + case "list": + return set(normalize(predicted)) == set(normalize(gold)) + case "table": + return compare_tables(predicted, gold) # Column + row overlap +``` + +### 4.3 Question Metadata Format + +Each question in the JSON dataset includes: + +```json +{ + "id": "spider_dev_042", + "question": "How many employees are in the Engineering department?", + "database": "company_db", + "gold_sql": "SELECT COUNT(*) FROM employees WHERE department = 'Engineering'", + "gold_answer": "42", + "answer_type": "integer", + "difficulty": "easy", + "tables_involved": ["employees"] +} +``` + +The `gold_sql` is used for progress computation (running the gold query on the DB to get the reference answer). The `gold_answer` is the cached expected result. Both are hidden from the agent. + +### 4.4 Multi-DB Verification (Post-MVP) + +**MVP**: Single database per question. Accept correct result on the original DB. + +**Post-MVP**: For each question, generate 1-2 variant databases with the same schema but different data. An answer must be correct across all variants. + +Variant generation strategies (prioritized): +1. **Irrelevant row injection** — add records outside the question's filter scope +2. **Join multiplicity trap** — add duplicates in bridge tables +3. **ID remap** — apply bijection to primary keys, update foreign keys + +(See Section 6.2 for the full metamorphic testing backlog.) + +--- + +## 5. MVP Development Track + +The goal is to get a **working, submittable solution as fast as possible**, then improve iteratively. Each phase has a "done when" gate. Do not start the next phase until the current one passes its gate. + +### Phase 1: Scaffold & Stub (Day 1) + +**What**: Run `openenv init sql_env`, customize the generated models/server/client stubs to match our Pydantic models. Get a Docker container that starts and responds to reset/step. + +**Tasks**: +1. `openenv init sql_env` +2. Replace generated models with `SQLAction`, `SQLObservation` from Section 2.2 +3. Implement stub `SQLEnvironment.reset()` → returns hardcoded observation +4. Implement stub `SQLEnvironment.step()` → accepts action, returns hardcoded observation +5. Implement `SQLEnv(EnvClient)` client with `_step_payload`, `_parse_result`, `_parse_state` +6. `openenv build` and `openenv validate` + +**Done when**: `openenv validate --verbose` passes. Client can connect, reset, step, and receive typed observations. + +### Phase 2: Core Loop with Terminal Reward (Days 2-4) + +**What**: Wire up real SQLite databases, implement the action handlers, add terminal-only reward (binary correctness on ANSWER). This is a **submittable environment** — sparse reward, but functional. + +**Tasks**: +1. Download Spider dev databases (SQLite files) and a curated question set (30-50 questions) +2. Implement `reset()`: pick random question, load DB, return initial observation with table names +3. Implement DESCRIBE handler: query `sqlite_master` + `PRAGMA table_info` +4. Implement SAMPLE handler: `SELECT * FROM {table} ORDER BY RANDOM() LIMIT 5` +5. Implement QUERY handler: execute read-only SQL with timeout, truncate results to 20 rows +6. Implement ANSWER handler: compare to gold answer using `verify_answer()`, return reward +7. Add budget tracking (15 steps), timeout handling +8. SQL sandboxing: read-only connection, statement timeout, no DDL + +**Done when**: Can run a full episode manually — reset, DESCRIBE a table, run a query, submit an answer, get correct/incorrect reward. Works in Docker via WebSocket. + +### Phase 3: Dense Reward (Days 5-7) + +**What**: Add reward Layers 1 and 2 (operational validity + progress-to-target). This makes the environment trainable — agents get feedback before the terminal step. + +**Tasks**: +1. Implement `reward.py` with the 3-layer reward computation +2. Layer 1: Track executed queries (hash set for repeat detection), track schema exploration (set of described tables/columns), compute `r_exec_ok`, `r_new_info`, `r_repeat`, `r_cost` +3. Layer 2: After each QUERY, run gold SQL on the DB, compare query result to gold result using the progress metric (type-dependent), bin to 5 levels, compute improvement-only reward +4. Wire reward computation into `step()` — return stepwise reward in observation +5. Add reward capping logic (sum of step rewards <= 0.5, negative floor at -0.2) +6. Test: run episodes, verify reward signals are sensible + +**Done when**: Reward signal varies meaningfully across different agent behaviors (random exploration gives some small positive reward; targeted queries give progress reward; correct answer gives terminal reward). + +### Phase 4: Training Pipeline (Days 8-12) + +**What**: Implement the GRPO training script following the Wordle tutorial pattern. Train a small model. Produce baseline vs. trained comparison. + +**Tasks**: +1. Write `rollout_func` that plays full SQLEnv episodes via WebSocket client +2. Design system prompt for the SQL agent (schema understanding, query strategy, answer formatting) +3. Implement reward functions for TRL (`reward_correctness`, `reward_progress`, `reward_operational`) +4. Set up training config (Qwen3-1.7B or similar small model, GRPO via TRL+vLLM) +5. Run training (start small: 100 episodes, observe learning curves) +6. Implement Green Agent wrapper (automated evaluation: run N episodes, report success rate) +7. Produce comparison: random policy vs. trained model (success rate, avg steps, avg reward) +8. Debug and iterate on reward weights if training doesn't converge + +**Done when**: Trained model measurably outperforms random baseline on success rate. Training notebook runs end-to-end. Green Agent reports evaluation metrics. + +### Phase 5: Polish & Submit (Days 13-16) + +**What**: Deploy to HF, write blog, prepare demo. + +**Tasks**: +1. `openenv push` to HuggingFace Spaces +2. Clean up GitHub repo: README, requirements, training notebook, results +3. Write HF blog post: + - Hook: "What if AI could learn to query databases like a data analyst?" + - Problem: Static benchmarks don't teach exploration strategy + - Solution: SQLEnv — interactive environment with dense reward + - Results: Learning curves, before/after comparison, example episodes + - Technical: Reward architecture, OpenEnv integration +4. Record/screenshot side-by-side demo (untrained vs. trained agent) +5. Final validation: someone else can `pip install`, connect to HF Space, run training notebook + +**Done when**: All 3 submission artifacts are live (HF Space, GitHub repo, HF blog). Blog tells a compelling story with real results. + +### Phase Summary + +| Phase | Days | Produces | Risk if Skipped | +|---|---|---|---| +| 1. Scaffold | 1 | Stub environment in Docker | Can't build anything | +| 2. Core Loop | 2-4 | Working env with terminal reward | No submittable environment | +| 3. Dense Reward | 5-7 | Trainable environment | Terminal-only reward may not train | +| 4. Training | 8-12 | Trained model + comparison | No "Technical Excellence" or "Demo" | +| 5. Polish | 13-16 | Blog + HF Space + GitHub | No submission | + +**Minimum viable submission**: Phases 1-2-4-5 (skip dense reward, train with terminal-only). This is risky — terminal-only reward is sparse and may not produce a meaningful trained model — but it's submittable. + +**Recommended path**: All 5 phases in order. Dense reward (Phase 3) is what makes training work and what demonstrates "Technical Excellence." + +--- + +## 6. Post-Submission Improvements (Backlog) + +These are improvements to pursue **only after** a working submission exists. Ordered by expected impact. + +### 6.1 Multi-Database Verification + +**Impact**: High. Defends against "accidental correctness" — queries that return the right answer for the wrong reasons on one dataset. + +**What**: For each question, generate 1-2 variant SQLite databases with the same schema but different data distributions. Answer must be correct across all variants. + +**Implementation**: Script that takes a base DB + gold SQL, runs targeted mutations (see 6.2), re-runs gold SQL to get new expected answer, packages as variant DB. + +### 6.2 Metamorphic Testing Suite + +Ten database mutations that catch common SQL errors without requiring "SQL correctness" checking: + +| # | Test | What It Catches | Best For | +|---|---|---|---| +| 1 | Row-order permutation | Missing ORDER BY, positional dependencies | All types | +| 2 | Irrelevant row injection | Missing filters, wrong date logic | Filtered aggregates | +| 3 | Dangling entity injection | Incorrect outer joins, wrong join direction | Aggregates over fact tables | +| 4 | Key re-encoding (ID remap) | Hard-coded IDs, magnitude assumptions | All types | +| 5 | Duplicate bridge rows | Missing DISTINCT, cartesian joins | Unique counts | +| 6 | NULL perturbation | COUNT(col) vs COUNT(*), NULL comparison bugs | Counts, joins | +| 7 | Unit scaling (numeric × factor) | Wrong aggregation, measure/count confusion | Numeric aggregates | +| 8 | Noise facts (orphan FKs) | Missing joins, fact-only queries | Join-dependent queries | +| 9 | Tie injection at k-th boundary | Brittle top-k, missing tiebreak | Top-k/ranking | +| 10 | Label swap (category permutation) | Surface-string heuristics, shortcut patterns | Category-based queries | + +**MVP subset**: Tests 2, 4, 5 (highest signal, cheapest to implement). + +### 6.3 Two-Tier Action Space (RA/CTE Mode) + +**Impact**: Medium. Makes intermediate rewards easier (subset/superset signals on intermediate tables) and improves dialect portability. + +**What**: Add structured relational algebra operations (filter, join, group, union) as an alternative to raw SQL. Agent can build intermediate tables step-by-step. + +**Why it helps**: QueryGym shows this makes the environment more RL-friendly — less syntax failure, easier partial credit, engine-agnostic.

Even if the environment returns only the “correct” signal, the trainer can compute additional reward terms from observations.

([arXiv][2]) + +**What to steal:** + +* For list-type answers (top-k rows, grouped outputs), subset/superset rewards are very natural and robust. + +--- + +## 4) A reward design that’s dense, meaningful, and hard to game + +Your current doc has a good high-level weighting, but I’d change *how* you implement intermediate reward so it teaches the right skills without leaking the answer or being exploitable. + +### 4.1 Split reward into 3 layers (this is the key) + +#### Layer 1 — **Operational validity** (stepwise, low leak) + +Reward “being able to operate the tool” and not waste steps: + +* `r_exec_ok`: +ε when a query executes successfully (no syntax/runtime error) +* `r_new_info`: +ε when the action reveals *new* info (new table described, new column seen, new value distribution sampled) +* `r_repeat`: small penalty (or zero reward) for repeating identical queries or identical observations +* `r_cost`: tiny step cost (keeps trajectories short) + +This is similar in spirit to the “syntax / format / turns” components in SQL-TRAIL’s panel. ([arXiv][3]) + +**Important tweak:** prefer **small positive signals** + “no reward” over heavy negative penalties. Strong negative shaping often makes agents risk-averse and can destabilize learning (PaVeRL-SQL explicitly designs around sparsity/instability concerns). ([arXiv][4]) + +#### Layer 2 — **Progress-to-target** (stepwise, oracle-based but *coarsened*) + +This is where you densify correctness *without waiting for ANSWER*. + +Maintain a hidden “best progress so far” metric. After each `QUERY`, compute: + +* If the question is an **aggregate** (count/sum/avg): + + * `progress = 1 - min(1, |pred - gold| / denom)` (choose denom robustly; e.g., max(1, |gold|)) +* If the expected answer is a **set/list**: + + * `progress = Jaccard(pred_set, gold_set)` or overlap@k +* If the expected answer is a **table**: + + * score column overlap + row overlap separately (like fractional exec accuracy; PaVeRL uses column-based partial reward). ([arXiv][4]) +* If you have **gold SQL** available: + + * you can additionally compute coarse structural signals (tables referenced, join graph overlap), but be careful: lexical overlap (e.g., bigrams) can overfit and may reward “copying style” rather than semantics (SQL-TRAIL still uses a bigram term, but I’d keep it very low weight). ([arXiv][3]) + +Then define step reward as **improvement**: + +* `r_progress = clamp(progress_t - best_progress, 0, 1)` +* `best_progress = max(best_progress, progress_t)` + +This avoids agents “farming” reward by oscillating. + +This is the same core idea as QueryGym’s subset/superset intermediate reward and terminal equivalence check, just adapted to your action space. ([arXiv][2]) + +#### Layer 3 — **Terminal correctness** (big) + +When the agent uses `ANSWER`, compute final correctness (multi-db test suite etc.) and give a large terminal reward. + +SQL-TRAIL still keeps binary execution correctness as the primary term (weighted highest), and you should too. ([arXiv][3]) + +--- + +### 4.2 A concrete reward recipe that will actually train + +Here’s a version that’s dense but not messy: + +* Terminal: + + * `R_final = 1.0` if answer matches across test DBs else `0.0` +* Stepwise (each `QUERY`): + + * `+0.02` if executed successfully + * `+0.05 * (progress_t - best_progress)+` (only improvements) + * `+0.01` if reveals new schema info / new column stats / new table sampled (capped per episode) + * `-0.005` step cost + * `-0.01` if exact same SQL was already run (hash match), or if observation identical N times + +Then **cap total shaping** so it can’t exceed the value of being correct, e.g.: + +* `sum(step_rewards) <= 0.5` +* `R_episode = 1.5*R_final + sum(step_rewards)` + +Why caps matter: otherwise the agent learns to “explore forever” and harvest shaping. + +This is conceptually aligned with “reward panel” thinking (multiple terms, correctness dominates), but implemented in a way that produces *incremental credit assignment* during exploration. ([arXiv][3]) + +--- + +## 5) Make the environment “general” by widening actions carefully (don’t just dump raw SQL) + +Your current action set is fine, but if you want generality *and* better learning dynamics, copy QueryGym’s strongest idea: + +### 5.1 Two-tier action space (beginner → advanced) + +**Tier 1 (Structured / engine-agnostic):** + +* Exploration actions (preview table, sample values, get schema) +* **Relational algebra ops** (filter/join/group/union…) that build an intermediate table/CTE + +QueryGym uses exactly this: exploration + relational algebra operations, and it’s explicitly designed to be engine-agnostic and RL-friendly. ([arXiv][2]) + +**Tier 2 (Raw SQL):** + +* Free-form SQL once the agent has learned the “tool use” basics + +This gives you: + +* easier reward shaping early (subset/superset signals on intermediate tables) +* less syntax failure early +* dialect portability + +### 5.2 Observation classes (copy QueryGym’s 4 buckets) + +QueryGym categorizes observations into: overview, exploration result, intermediate table info, error feedback. ([arXiv][2]) + +Do the same; it keeps prompts stable and makes training easier. + +**Crucial practical detail:** always include *structured summaries* (columns, rowcount, sample rows) rather than dumping full query results. SQL-TRAIL explicitly mentions truncated dataframe previews / error messages as observation content in their loop. ([arXiv][3]) + +--- + +## 6) “Dense reward” gotchas (where these environments usually fail) + +1. **Reward leakage (agent learns to infer gold from reward)** + + * If you give very specific progress signals, the agent can “hill-climb” without truly reasoning. + * Mitigation: coarsen progress into bins (0, 0.25, 0.5, 0.75, 1), and keep step rewards small vs terminal. + +2. **Reward farming via exploration** + + * If `DESCRIBE` always pays, the agent will describe everything. + * Mitigation: novelty reward must be **capped** and/or **relevance-weighted** (e.g., only reward describing tables whose names overlap with question tokens, or limit “new info” reward to first N actions). + +3. **Over-penalizing errors** + + * Heavy negative penalties can make the agent stop exploring; PaVeRL-style partial rewards are popular partly because they reduce that brittleness. ([arXiv][4]) + * Mitigation: prefer “no reward” for invalid steps + small step cost. + +4. **Lexical similarity rewards that overfit** + + * Bigram/keyword overlap encourages copying gold SQL style, not semantics. + * SQL-TRAIL includes a bigram term, but treat this as a stabilizer, not a main objective. ([arXiv][3]) + +5. **Equivalence checking is tricky** + + * Multi-db test suite helps, but adds complexity/compute. (You already captured this well.) + * A cheaper intermediate option is QueryGym’s subset/superset checks on intermediate result tables.

counts should not. + +Catches: mixing up measure columns, wrong aggregation, or accidentally answering a count-like proxy. + +(You can use this even without gold SQL if the question type is known.) + +8) Add “noise facts” outside the join path + +Mutation: insert new fact rows that reference nonexistent dimension keys (or keys in a separate, unused region of the keyspace). + +Should hold for: questions that correctly enforce referential joins. + +Catches: queries that don’t join properly (using only fact table attributes), or that implicitly treat orphaned facts as valid. + +9) Tie-injection for top-k (robustness to ties) + +Mutation: create ties around the k-th boundary (e.g., two products with equal revenue). + +Expected behavior: results may be non-unique unless a deterministic tiebreak is specified. + +Catches: brittle evaluation + agent reliance on incidental ordering. + +Practical fix: grade as set match or accept multiple valid orderings unless tie-break is explicitly in the task. + +10) Counterfactual “swap labels, preserve structure” + +Mutation: permute category/string labels via a bijection (rename categories, regions, etc.) while preserving relationships. + +Should hold for: numeric aggregates;

The Multi-Hop Insight (Why This Works for RL) + +Spider questions are **already multi-hop**—not just because they require SQL JOINs, but because an agent starting with zero knowledge must: + +**Example: "How many departments are managed by someone born in Alabama?"** + +| Hop | Agent Action | What It Learns | +|-----|--------------|----------------| +| 1 | `DESCRIBE head` | Discovers `born_state` column exists in `head` table | +| 2 | `QUERY: SELECT head_id FROM head WHERE born_state = 'Alabama'` | Finds specific head IDs: [5, 12, 23] | +| 3 | `DESCRIBE management` | Discovers `head_id` and `department_id` columns | +| 4 | `QUERY: SELECT department_id FROM management WHERE head_id IN (5,12,23)` | Gets department IDs: [2, 7] | +| 5 | `QUERY: SELECT COUNT(DISTINCT department_id) FROM management JOIN head ...` | Refines into proper JOIN query | +| 6 | `ANSWER: 2` | Submits final answer | + +**Key point**: The schema is hidden initially. Agent only sees table names at start. Must actively probe to discover: +- What columns exist (can't guess `born_state` is in `head` table) +- How tables relate (must discover `management` links `department` ↔ `head`) +- What data looks like (needs to sample to understand values) + +**Why Spider specifically**: +- 71% of queries require JOINs across multiple tables +- 17% require nested subqueries (decomposition needed) +- Schema initially hidden forces exploration +- Multiple difficulty levels (easy: 1-2 tables → hard: 5+ tables with subqueries) +- Gold SQL available for reward computation +- 200 databases across 138 domains = generalization testing + +--- + +## 3. Critical Design Decisions (For Team Discussion) + +### Decision 1: Reward Architecture + +**The Challenge**: If we only reward the final answer (terminal reward), the agent has no signal during exploration—it's like playing chess but only learning "win/lose" without feedback on good/bad moves. + +**Our Solution**: Three reward layers that sum together: + +``` +Episode Reward = Terminal Correctness (0 or 1.0) + Exploration Progress (max 0.5) +``` + +**Layer 1 - Operational** (teaches "how to use the tool"): +- Small positive: query runs without error (+0.02) +- Small positive: discovered new table/column info (+0.01, capped) +- Small negative: repeated exact same query (-0.01) +- Tiny cost: each step (-0.005, keeps episodes short) + +**Layer 2 - Progress** (teaches "am I getting closer?"): +- After each query, compute: how close is result to gold answer? +- Only reward *improvement* over best-so-far +- Coarsen to 5 levels {0, 0.25, 0.5, 0.75, 1.0} to prevent "reward hacking" + +**Layer 3 - Terminal** (teaches "what's the goal?"): +- Correct answer: +1.0 +- Incorrect or timeout: 0.0 + +**Why terminal must dominate**: With exploration capped at 0.5, a correct answer is always worth 2x the maximum exploration reward. This prevents agents from "gaming" the system by just exploring without ever answering. + +**Open Question for Team**: Should we expose these as separate reward components to the trainer (TRL supports multi-reward), or sum them into a single scalar? Trade-off: separate = more control for research, single = simpler to tune. + +### Decision 2: Action Space (What Can Agents Do?) + +| Action | Purpose | Example | +|--------|---------|---------| +| `DESCRIBE table_name` | Learn schema | `DESCRIBE employees` → see column names, types | +| `SAMPLE table_name` | See example data | `SAMPLE orders` → get 5 random rows | +| `QUERY sql_string` | Test hypothesis | `QUERY: SELECT COUNT(*) FROM orders WHERE status='shipped'` | +| `ANSWER value` | Submit final answer | `ANSWER: 42` | + +**Key constraints**: +- Budget: 15 steps per episode (configurable) +- Sandboxing: Read-only SQLite, 5 second timeout, SELECT-only +- Truncation: Query results limited to 20 rows (agent sees summary, not full data) + +**Design Philosophy**: This is intentionally a POMDP (Partially Observable). The agent doesn't see the full database—just like a real analyst wouldn't. This forces strategic exploration. + +**Open Question for Team**: Should we add a "HINT" action that reveals join paths after N failed queries? Helps curriculum learning but might be a crutch. + +### Decision 3: Dataset Curation + +**MVP Scope**: 50-100 questions from Spider dev set + +**Selection Criteria**: +- **Easy** (40%): Single table, basic WHERE/COUNT + - *"How many orders were placed in January?"* +- **Medium** (40%): 2-3 tables, JOINs, GROUP BY + - *"What's the total revenue per customer?"* +- **Hard** (20%): 4+ tables, subqueries, aggregates + - *"Find customers who ordered from every product category"* + +**Answer Type Support**: +- Integer (counts, IDs) → exact match +- Float (averages, sums) → 1% tolerance +- String (names, statuses) → case-insensitive normalized +- List (top-k results) → order-insensitive set comparison +- Table (multi-column results) → column + row overlap metrics + +**Open Question for Team**: Should we hand-pick questions or sample randomly by difficulty? Hand-picking ensures diversity, random ensures unbiased evaluation. + +--- + +## 4.

Change Overview + +### What We're Changing +Add 15-20 error-recovery SFT trajectories to the existing `generate_sft_data.py` script. These trajectories show the model querying with a wrong column or table name, receiving a SQL error, re-examining the schema via `describe` or `sample`, then writing a corrected query and submitting the correct answer. + +### Why We're Changing It +Error loops are the #1 reward killer in GRPO training. Run 7 analysis shows the model repeats the same failing query 3-8x because SFT only demonstrates happy paths (describe -> query -> answer). The base policy has no learned pattern for recovering from errors. Adding error-recovery demonstrations teaches the model to: (1) recognize SQL errors, (2) re-examine schema instead of retrying blindly, (3) construct a corrected query. + +### Success Criteria +- 15-20 error-recovery trajectories added to `data/sft/sft_trajectories.json` alongside existing 100 happy-path trajectories +- Each trajectory contains at least one deliberate wrong query -> error -> describe/sample -> corrected query -> correct answer sequence +- Trajectories use the same message format (system/user/assistant tool_calls/tool roles) and tool definitions as existing SFT data +- Arguments remain JSON strings (not dicts) per Qwen3 tokenizer constraint +- Existing happy-path generation remains unchanged + +--- + +## 2. System Context + +### Current Behavior +`scripts/generate_sft_data.py` generates 100 multi-turn SFT trajectories, all happy paths: +1. `describe()` each table in `tables_involved` +2. `query()` with the gold SQL +3. `answer()` with the gold answer + +Every trajectory succeeds on the first query attempt. The model never sees what happens when a query fails or how to recover. + +### Architecture Context +The SFT data feeds into a two-phase training pipeline: SFT warmup (teaches tool-calling format and workflow) followed by GRPO (teaches optimization via reward). The SFT phase creates the base policy that GRPO refines. Without error-recovery patterns in SFT, GRPO has no foundation to build recovery behavior on. + +``` +questions_train.json --> generate_sft_data.py --> sft_trajectories.json --> SFT training --> GRPO training + | | + SQLEnvironment 100 happy-path + N error-recovery + (real DB execution) +``` + +### Entry Points + +| Entry Point | Trigger | Current Flow | +|-------------|---------|--------------| +| `scripts/generate_sft_data.py::main()` | CLI invocation | Loads questions, generates happy-path trajectories, selects diverse subset, writes JSON | +| `scripts/generate_sft_data.py::generate_trajectory()` | Called per question | Builds one multi-turn trajectory: describe tables -> query gold SQL -> answer | + +### Data Flow + +| Data | Source | Shape/Type | Destination | +|------|--------|------------|-------------| +| Training questions | `data/questions/questions_train.json` | `list[dict]` with question_text, gold_sql, tables_involved, etc. | `generate_sft_data.py` | +| SFT trajectories | `generate_sft_data.py` | `list[dict]` with `messages` (chat format) and `tools` (tool definitions) | `data/sft/sft_trajectories.json` | +| Tool definitions | `training/trl_adapter.py::get_tool_definitions()` | `list[dict]` JSON tool schema | Embedded in each trajectory's `tools` key | +| Environment responses | `SQLEnvironment.step()` | `SQLObservation` with `.result`, `.error`, `.reward` | Message `content` in tool role turns | + +--- + +## 3.

Same signature pattern (env, question) -> dict or None. Keeps error-recovery logic separate from happy-path logic. | +| `_make_wrong_query()` | Generate a plausible wrong SQL from a gold SQL and schema | Encapsulates the error-fabrication logic. Testable in isolation. Called by the trajectory builder. | +| Integration in `main()` | Generate error-recovery trajectories after happy paths, append to output | Minimal change to existing flow. Error-recovery examples added as a separate pass. | + +### Abstraction Level + +- **Current level:** Flat -- one `generate_trajectory()` function builds the full message list procedurally. `main()` orchestrates the loop. No classes, no inheritance. +- **Recommendation:** Match existing flat style. Add `generate_error_recovery_trajectory()` as a sibling function to `generate_trajectory()`. Extract `_make_wrong_query()` as a helper since it has distinct logic (SQL mutation). Do not introduce trajectory builder classes or strategy patterns. + +### Anti-Patterns to Avoid + +- Do not create an abstract TrajectoryGenerator class hierarchy -- the codebase uses plain functions +- Do not hardcode wrong queries as literal strings -- generate them from real schema info so they produce authentic error messages +- Do not modify `generate_trajectory()` to optionally inject errors -- keep happy-path and error-recovery generation separate and composable +- Do not increase `MAX_SFT_QUESTIONS` from 100 -- error-recovery trajectories should be additive, not replace happy-path ones + +--- + +## 5.

Open Questions + +| Question | Why It Matters | Who Can Answer | +|----------|----------------|----------------| +| Should error-recovery trajectories go through `select_diverse_subset()` or be added unconditionally? | If filtered, some may be dropped; if unconditional, total count exceeds 100 | Implementation decision -- recommend unconditional append since 15-20 is already curated | +| What types of wrong queries to prioritize? | Wrong column names vs wrong table names vs syntax errors have different recovery patterns | Run 7 analysis -- focus on wrong column/table names as these are the observed GRPO failure modes | +| Should the wrong query be a mutation of the gold SQL or a completely different query? | Mutations are more realistic (model approximates but gets column name wrong) | Recommend mutation: swap a column name, use wrong table, drop a JOIN condition | + +--- + +## 7.

The environment is the product. It provides reward signals, action space, and episode structure that enable any RL algorithm to train agents that explore databases iteratively, the way human data analysts do. + +## The Problem + +Text-to-SQL benchmarks (Spider, BIRD, WikiSQL) evaluate one-shot SQL generation: given a question and schema, produce the correct query. This misses how data analysis works. Analysts don't write perfect queries from scratch — they explore schemas, run test queries, observe results, refine hypotheses, and iterate toward an answer. + +No RL environment captures this multi-turn exploration process. Without one, we cannot train agents that develop investigative reasoning strategies. + +## What We Build + +An OpenEnv-compatible RL environment where: + +- **Schema starts hidden.** Agents see only table names at reset. They must discover columns, types, relationships, and data through DESCRIBE and SAMPLE actions. +- **Exploration earns rewards.** A 3-layer reward architecture provides feedback during exploration, not just at termination. This enables RL convergence. +- **Actions mirror analyst workflows.** DESCRIBE (learn schema), SAMPLE (see data), QUERY (test hypotheses), ANSWER (submit result) — these reproduce the investigative loop of a working analyst. +- **Multi-hop reasoning emerges naturally.** Spider questions requiring JOINs across 2-5+ tables force agents to discover schemas, identify relationships, and compose queries incrementally. + +## What We Do Not Build + +- A text-to-SQL model (we build the environment others train on) +- A production SQL agent (the trained agent demonstrates the environment, nothing more) +- A static benchmark (the environment is interactive and stateful) + +## Why OpenEnv + +OpenEnv (Meta/HuggingFace) provides: + +- Gym-oriented API (`reset()`/`step()`) familiar to RL practitioners +- Docker isolation for safe SQL execution +- HuggingFace Spaces deployment +- TRL/GRPO integration via `environment_factory` pattern +- Standard evaluation harness for reproducible comparisons + +## Design Principles + +### 1. The Environment Owns Rewards, Not Reasoning +The environment executes SQL, computes rewards, and enforces constraints. The agent owns all reasoning — schema discovery strategy, query composition, when to answer. We removed Ollama/LLM inference from the environment deliberately: the environment judges, it does not participate. + +### 2. Terminal Correctness Dominates +Exploration rewards (capped at 0.5) never exceed terminal correctness (+1.0). An agent that explores but never answers scores less than one that answers correctly with minimal exploration. This prevents reward gaming. + +### 3. Partial Observability Is the Point +The POMDP structure (hidden schema, truncated results, step budget) forces strategic exploration. It makes the environment worth training on. + +### 4. Dense Rewards Enable Training +The 3-layer reward architecture (operational + progress + terminal) exists to make RL training feasible on small models. Without dense rewards, a <0.5B parameter model cannot learn from sparse terminal-only signals. + +### 5. Small Models Over Large +Target model size: <0.5B parameters (e.g., Qwen3-0.6B). The goal is demonstrating that the environment produces learning signals, not achieving SOTA accuracy. A small model showing clear improvement over random proves more than a large model with marginal gains. + +## Competition Context + +**OpenEnv Challenge** — Create a real-world RL environment and demonstrate training on it. + +**Evaluation criteria:** +1. Creative and robust use of OpenEnv +2. Technical excellence +3. Storytelling +4. Open-source demo +5. Green Agent wrapper + +**Our position:** No interactive SQL exploration environment exists.
