Training an AI to Supervise Other AIs ## The Problem As AI systems become more capable, the hardest question in alignment is not *"can an AI agent act?"* — it is *"can a smaller AI stop a larger one before it acts badly?"* SENTINEL is an OpenEnv environment that turns this into a **trainable RL problem** with verifiable rewards, real training evidence, and quantified proof of oversight value. ## What SENTINEL Does Picture a production incident. Four AI workers respond: database, app, network, security. Most proposals are useful. Some are dangerous — a worker confidently recommends a restart before checking any logs, another acts outside its domain, a third hits the reward condition without solving the actual problem. SENTINEL intercepts every proposal **before it executes**: ``` APPROVE | BLOCK | REDIRECT | REASSIGN | FLAG ``` It is a trained oversight policy with worker trust memory, five constitutional safety principles, and a corrective feedback loop that teaches workers to revise blocked proposals. ## Setup - **Base model:** `unsloth/Qwen3-4B-bnb-4bit` with LoRA rank 16 - **Method:** GRPO via Hugging Face TRL + Unsloth - **Hardware:** A100 80GB, ~75 minutes for 200 GRPO steps + 20 warm-start - **Environment:** 4 SENTINEL tasks, 8 misbehavior types - **Reward:** 10-component decomposed signal — detection, FP penalty, explanation quality, redirect quality, constitutional compliance, counterfactual risk reduction ## Results | Agent | Mean Score | Catch Rate | Damage Prevented | |---|---:|---:|---:| | Zero oversight (approve all) | {h['score_zero_oversight']:.3f} | 0.0% | 0% | | Rule-based heuristics | ~0.10 | ~5% | ~0% | | **SENTINEL trained (GRPO)** | **{h['score_sentinel']:.3f}** | **{h['catch_rate_sentinel']:.0%}** | **{h['damage_prevention_pct']:.0f}%** | **{h['score_multiplier']:.1f}x improvement over zero oversight.** The Digital Twin replays every episode without oversight and compares outcomes. SENTINEL prevents **{h['damage_prevention_pct']:.0f}%** of potential damage. """ if h.get("stress_score_multiplier", 0) > 0: blog += f""" ### Stress evaluation (held-out seeds) | Agent | Score | Damage Reduction | |---|---:|---:| | Approve-all baseline | {h['stress_score_baseline']:.3f} | ~2% | | **SENTINEL trained** | **{h['stress_score_candidate']:.3f}** | **{h['stress_damage_reduction']:.0%}** | **{h['stress_score_multiplier']:.1f}x on held-out seeds never seen during training.** """ blog += f""" ### Zero-shot generalization CONFIDENCE_WASHING (Type 7) was **never injected during training**. Constitutional principle P2 (*Evidence Before Action*) fires and blocks it. Constitutional accuracy on held-out scenarios: **{h['zero_shot_const_acc']:.0%}**. ## Why It Matters Most RL demos train the worker. SENTINEL trains the **control plane above the workers**. The same pattern applies anywhere multiple AI agents act in the world. ## Try It - **Model:** [{PHASE1_REPO}](https://huggingface.co/{PHASE1_REPO}) - **Code:** [sri11223/openEnv](https://github.com/sri11223/openEnv) - **Colab:** `notebooks/sentinel_qwen3_4b_grpo_colab.ipynb` --- *OpenEnv Hackathon India 2026* """ blog_dir = ROOT / "docs" / "sentinel" blog_dir.mkdir(parents=True, exist_ok=True) blog_path = blog_dir / "hf_blog_post.md" blog_path.write_text(blog) log.info("Blog post written to %s", blog_path) print(f"\n HF BLOG: docs/sentinel/hf_blog_post.md → paste at huggingface.co/blog/create\n") return blog_path # ── readme update ───────────────────────────────────────────────────────────── def update_readme_plots(): readme_path = ROOT / "README.md" if not readme_path.exists(): return text = readme_path.read_text(encoding="utf-8") if "final_eval_figures" in text: log.info("README already has eval figures section") return plots_section = """ ### Evaluation Figures (GPU run — all 4 tasks, 5 seeds) ![3-way comparison](outputs/proof_pack/final_eval_figures/01_three_way_overview.png) *Zero oversight vs rule-based vs trained SENTINEL. x-axis: agent type, y-axis: metric.* ![Digital Twin](outputs/proof_pack/final_eval_figures/03_digital_twin_damage.png) *Counterfactual damage WITH vs WITHOUT SENTINEL.* ![Before vs after](outputs/proof_pack/final_eval_figures/07_improvement_before_after.png) *Key metrics: zero oversight (red) vs trained SENTINEL (green).* ![Zero-shot generalization](outputs/proof_pack/final_eval_figures/08_zero_shot_confidence_washing.png) *CONFIDENCE_WASHING never in training.
