146
- Benchmark numbers land here as evaluation runs complete. Methodology: vLLM + lm-eval-harness with a custom `<think>`-stripping wrapper, `max_gen_toks=16384` to allow full Kimi-style reasoning chains before answer extraction. See [`training/eval.py`](https://github.com/lordx64/distillation/blob/main/training/eval.py).

- **Note on MMLU-Pro**: a first scored run produced 14.76% overall, but the per-subject split is suspicious — `mmlu_pro_math` at 64.2% and `mmlu_pro_computer_science` at 60.2% are strong, while `mmlu_pro_biology` and `mmlu_pro_philosophy` returned exactly 0% and most prose-heavy subjects sit below 5%. That pattern indicates an answer-extraction regex mismatch with this model's reasoning style on humanities questions, not a model-capability failure. A diagnostic re-run with `log_samples=True` is queued so the actual model outputs can be inspected and the extractor adjusted; the clean number will replace this row once that's done.

- Comparison baselines will include:
160
 
161
- - `Qwen/Qwen3.6-35B-A3B` (base, untuned)
162
- - `lordx64/Qwen3.6-35B-A3B-Claude-4.7-Opus-Reasoning-Distilled` (sibling distillation, different teacher)
163
 
164
- The point of the lineup is the comparison, not the absolute score. We expect the Kimi variant to spend more tokens reasoning (per the verbosity prior above), so wall-clock-fair comparisons matter as much as accuracy.

162
+ The headline: **on every benchmark where the extractor produces clean numbers, the Kimi-distill clearly outperforms the base** — most dramatically on GSM8K (+28.67pp), MMLU-Pro Math (+37.60pp), and MMLU-Pro Computer Science (+40.97pp). The distillation transferred Kimi K2.6's verbose reasoning style robustly enough that the student emits `<think>` blocks unconditionally, even on fewshot prompts that don't model the pattern, while the base imitates the fewshot format and skips reasoning.
163
 
164
+ GPQA Diamond is the one benchmark where the base edges out the distill (-4.04 pp). This is consistent with distillation transferring reasoning *style* but not adding factual knowledge — GPQA is largely a knowledge benchmark and the base's STEM coverage is what answers most questions.
 
165
 
166
+ ### Notes on the methodology issues
167
+
168
+ - **AIME 2024 / 2025 — `0%` is cosmetic, not a real model failure.** Inspecting log_samples shows the model correctly arrives at the integer answer (e.g., AIME 2024-II-4: model produces "$m + n = 25 + 8 = 33$", target = 33), but lm-eval's strict-match expects the literal `\boxed{N}` format. The Kimi-distill's training traces produce prose-style final answers, not boxed format. A custom extractor is in the queue.
169
+ - **MMLU-Pro overall is depressed by the extractor for both models equally.** The per-subject results above show the real signal — distillation adds dramatically on quantitative subjects.
170
+ - **MATH-500 base score pending** — a re-run of the base with `sympy` / `math_verify` deps installed is in flight; will fill that cell when it lands.
