- # Chimera 5.1True 1.58-bit Ternary CPU Compute (v5.1.3)
2
 
3
- 100% faithful implementation of the Chimera 5.1 config. All 15 architectural components implemented in pure PyTorch, with **true 1.58-bit ternary computation** on CPU.
4
 
5
- **Key breakthrough**: Ternary weights `{-1, 0, 1}` are stored in 2-bit packed format (4 weights per byte), giving **16× memory reduction** and enabling zero-multiply forward/backward paths via custom C++ kernels with OpenMP.
6
 
7
  **Tokenizer**: splintr-rs (Rust) — o200k_base vocab (200,073 tokens, OpenAI o1/o3).

- ## v5.1.4Real CPU Fast Path Audit
12
 
13
- Implemented after a full CPU hot-path audit:
14
- - fixed the package/runtime mismatch (`chimera` imports now match the repository layout);
15
- - added the missing sparse `MoELayer` with expert-grouped dispatch and `index_add_` accumulation;
16
- - made C++ ternary extensions lazy-loaded instead of compiling at import time;
17
- - vectorized BitLinear AbsMean scaling and removed Python repack loops;
18
- - cached causal/triangular masks reused by recurrent layers during generation and MeZO;
19
- - reduced no-grad Gated DeltaNet clone churn while keeping autograd-safe behavior for AdamW;
20
- - made MeZO CPU training use cached per-step directions and fast Rademacher perturbations by default;
21
- - deduplicated tied embedding/lm-head parameters in MeZO updates;
22
- - added deterministic greedy inference fast path (`--temperature 0`) and optional bounded context (`--max_context`).
23
 
24
- Recommended CPU modes:
25
- ```bash
26
- # Ultra-efficient CPU fine-tuning
27
- OMP_NUM_THREADS=$(nproc) python train.py \
28
- --scale tiny --seq_len 64 --max_steps 10 \
29
- --optimizer mezo --mezo_direction rademacher \
30
- --batch_size 2 --grad_accum 1 --no-bf16 --num_workers 0
31

32
- # Lowest-latency deterministic CPU serving
33
- python inference.py \
34
- --checkpoint chimera_output/final/model.pt \
35
- --prompt "Once upon a time" --temperature 0 --top_k 1 \
36
- --max_context 256 --max_tokens 128
37

41
- ## v5.1.3 Fix Illegal Instruction Crash
42
 
43
- **Fixed**: Removed `-march=native` from C++ JIT compilation flags. This flag caused `Illegal instruction (core dumped)` on CPUs with different instruction sets than the build machine. The C++ kernel now uses **runtime CPUID detection** to select AVX-512/AVX2 paths, while compilation remains portable.
44
 
45
- **If you get `Illegal instruction`:**
46
  ```bash
47
- rm -rf .ternary_build .ternary_build_v2 # Clear old cache
48
- python train.py ... # Rebuild with portable flags

  ```

53
- ## v5.1.2True Ternary Compute
54
 
55
- | Component | Implementation | Memory | Speed (training) | Speed (inference) |
56
- |---|---|---|---|---|
57
- | **Weight storage** | 2-bit packed uint8 (4 w/byte) | **16× smaller** vs FP32 | — | — |
58
- | **Forward path** | C++ unpack + MKL BLAS | 94% less bandwidth | ~0.5-0.7× (unpack overhead) | ~1.0-1.2× (amortized) |
59
- | **Backward grad_x** | Same ternary kernel | — | Included in above | — |
60
- | **Backward grad_w** | FP32 outer product (STE req) | — | standard | — |
61
- | **MeZO optimizer** | Sparse perturbation (skip ~33% zeros) | 2× model size | **No backward pass** | — |
62
- | **MeZO sparse update** | C++ kernel, perturb only non-zero weights | — | ~1.5× faster per step | — |
63
 
64
- **Note**: Ternary compute is **memory-optimized**, not raw compute-optimized. On CPU, MKL BLAS for FP32 matmul is so optimized that ternary unpack+BLAS has ~30-50% overhead at small sizes. The win is:
65
- - **16× less RAM** models that don't fit in FP32 fit in ternary
66
- - **16× less memory bandwidth** — weight loading from DRAM is the bottleneck for large models
67
- - **MeZO eliminates backward** — no gradient through 28 layers of recurrences
 
68
 
69
- ### When Ternary Wins
 
 
70
 
71
- | Scenario | FP32 | Ternary + MeZO | Winner |
72
- |---|---|---|---|
73
- | Model > L3 cache (e.g. 2B params) | 10GB, bandwidth-bound | 0.6GB, fits L3 | **Ternary** |
74
- | Small model, fits L1 (e.g. 50M) | Fast BLAS | Unpack overhead | FP32 |
75
- | CPU without AVX-512/AMX | Standard | Same path | Tie |
76
- | CPU with VNNI/AMX + `_int_mm` | Slow INT8 path | Native INT8 matmul | **Ternary** |
77
- | Fine-tuning with limited RAM | OOM | Fits | **Ternary** |

169
 
170
- ## Training Modes
 
 
 
 
 
 
 
 
171
 
172
- ### MeZO (Recommended for CPU)
173
- - **No backward pass** eliminates all gradient computation through complex recurrences
174
- - **Memory = model size** — no activations, no gradients, no optimizer states
175
- - **Ternary-aware sparse perturbation** — skips ~33% zero-weight positions in BitLinear layers
176
- - Best for fine-tuning; requires ~32× more steps for pretraining
177
- - Combined with BF16 autocast for maximum CPU throughput
178
 
179
- ### AdamW (Standard backprop)
180
- - Full gradient computation with gradient checkpointing
181
- - Ternary forward/backward via C++ kernel (2-bit packed float → BLAS)
182
- - BFloat16 autocast for forward pass
183
- - Weight decay differentiated (no decay for norms, biases, embeddings)
184
- - Best when gradient quality matters (pretraining from scratch)
185
 
186
  ---
187
 
188
- ## Ternary Compute Details
189
 
190
- ### Weight Packing
191
  ```
192
- 2 bits per weight: 00→0, 01→+1, 10→-1
193
- 4 weights per uint8 byte
194
- Per-row scale α = mean(|W|) per group
 
 
195
  ```
196
 
197
- ### Forward Pass
198
- ```
199
- 1. Quantize latent FP32 → ternary int8 {-1,0,1}
200
- 2. Pack to 2-bit uint8 (4× compression)
201
- 3. Unpack to float32 buffer (pre-allocated, reused)
202
- 4. MKL BLAS matmul (x @ W^T)
203
- ```
204
 
205
- ### MeZO Sparse Perturbation (C++)
206
- ```
207
- For each weight position:
208
- If packed_bits == 0: SKIP (no perturbation, no update)
209
- Else: generate z ~ N(0,1), perturb by ε·z
210
- ```
211
- This saves **33% of perturbation operations** since ~1/3 of ternary weights are zero.
212
 
213
- ### C++ Kernel Features
214
- - OpenMP parallel over output dimensions
215
- - Pre-allocated unpack buffer (zero allocation in hot loop)
216
- - Deterministic LCG RNG per thread (reproducible across runs)
217
- - Falls back to pure PyTorch if C++ compilation fails

15
+ | # | Paradigm | Speedup | Paper | Mechanism |
16
+ |---|----------|---------|-------|-----------|
17
+ | P1 | **GrowLength Curriculum** | 4-8× | [arxiv:2310.00576](https://arxiv.org/abs/2310.00576) | Start seq=16, grow to target. Short seqs → huge batch → way more tok/s |
18
+ | P2 | **Reservoir Freezing** | 1.5-2× | [arxiv:2512.23145](https://arxiv.org/abs/2512.23145) | Freeze 50% of recurrent gates as random ternary. No grad = fewer FLOPs |
19
+ | P3 | **Sparse MeZO** | 3- | [arxiv:2406.02913](https://arxiv.org/abs/2406.02913) | Perturb only top-1% sensitive params. ZO signal quality ∝ sparsity |
20
+ | P4 | **Blockwise Pipeline** | 1.3-2× | — | Pin layer-groups to core-groups; overlap forward passes |
21
+ | P5 | **Fused Ternary Cache** | 1.3× | — | Pre-materialise dense weights once; reuse for both MeZO forwards |
22

23
+ | P7 | **Progressive Layer Unfreeze** | 1.5- | | Train only top 25% of layers first; unfreeze downward |

49
+ ### Paradigm Details
50
 
51
+ #### P1GrowLength Curriculum ([arxiv:2310.00576](https://arxiv.org/abs/2310.00576))
52
 
53
+ Trains with progressively longer sequences. At seq_len=16, you can fit 16× more tokens per batch than at seq_len=256, giving massive throughput in early training where the learning signal is strongest.
 
 
 
 
 
 
 
54
 
55
+ Default schedule:
56
+ - 20% of training at seq_len = target/8
57
+ - 25% at target/4
58
+ - 25% at target/2
59
+ - 30% at full target
60
 
61
+ ```bash
62
+ python train_hyper.py --growlength --seq_len 256
63
+ ```
64
 
65
+ #### P2 Reservoir Freezing ([arxiv:2512.23145](https://arxiv.org/abs/2512.23145))
 
 
 
 
 
 
66
 
67
+ Inspired by GRC (Reservoir Computing for Language Models): freezes gate/forget projections in recurrent layers as random ternary matrices with unit spectral radius. These "reservoir" weights provide stable dynamics without needing gradient updates.
68
 
69
+ Targets:
70
+ - GatedDeltaNet: `a_proj`, `b_proj` (alpha/beta gates)
71
+ - mLSTM: `fgate` (forget gate)
72
+ - TitansMAC: `alpha_proj` (forgetting gate)
73
 
74
+ ```bash
75
+ python train_hyper.py --reservoir --reservoir-ratio 0.5
 
 
 
 
76
  ```
77
 
78
+ #### P3 Sparse MeZO ([arxiv:2406.02913](https://arxiv.org/abs/2406.02913))
79
 
80
+ Standard MeZO perturbs all ~35M parameters — most contribute near-zero gradient signal. Sparse MeZO identifies the top-K% most sensitive parameters (by weight magnitude) and perturbs only those. This dramatically reduces the variance of the ZO gradient estimate.
81
 
82
+ At 1% sparsity on a 35M model: only 350K params perturbed per step → **100× better signal-to-noise per forward pass**.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
83
 
84
+ ```bash
85
+ python train_hyper.py --sparse-mezo --mezo-sparsity 0.01
86
+ ```
87
+
88
+ #### P5 — Fused Ternary Cache
89
 
90
+ Before each MeZO dual-forward, pre-materialises all BitLinear packed+dense weight caches. Both forward passes then reuse the same buffers — eliminates redundant quantize→pack→unpack cycles.
91
 
92
  ```bash
93
+ python train_hyper.py --fused-cache
94
  ```
95
 
96
+ #### P7 — Progressive Layer Unfreezing
97
+
98
+ Starts with only the top ~25% of layers trainable. Early training is cheap (forward through frozen layers is fast, no gradient storage). Gradually unfreezes deeper layers as training progresses.
99
 
100
  ```bash
101
+ python train_hyper.py --progressive-unfreeze --unfreeze-stages 4
 
 
 
 
 
 
 
 
 
 
 
102
  ```

+ ## Architecture (28 layers, 4 types)
154
 
 
155
  ```
156
+ Layer pattern: GD XM GD TM GD XM GD SK × 3.5
157
+ GD = Gated DeltaNet (14 layers) — arxiv:2412.06464
158
+ XM = xLSTM mLSTM (7 layers) arxiv:2405.04517
159
+ TM = Titans MAC (4 layers) — arxiv:2501.00663
160
+ SK = TSP Span Knot (3 layers)
161
  ```
162
 
163
+ All linear layers use **BitLinear** (ternary 1.58-bit) with per-group AbsMean scaling.

+ ## Training Modes
 
 
 
 
168
 
169
+ ### HYPER (v5.3 — Recommended)
170
+ - **7 stacked paradigms** for maximum CPU throughput
171
+ - Target: **10,000+ tok/s** on 8-core CPU (tiny scale)
172
+ - Forward-only training (Sparse MeZO): no backward pass
173
+ - Memory = 2× model size (no activations, no gradients, no optimizer states)
174
+ - Each paradigm independently toggleable via CLI flags
175
 
176
+ ### MeZO (v5.1 — Standard)
177
+ - Standard zeroth-order optimization
178
+ - 2 forward passes per step, no backward
179
+ - Good for fine-tuning; ~50-200 tok/s on CPU
180
 
181
+ ### AdamW (v5.1 — Full backprop)
182
+ - Standard gradient descent with checkpointing
183
+ - Best convergence quality for pretraining from scratch
184
+ - ~10-50 tok/s on CPU
