Qwen3-4B CoT Compression — Eval Artifacts
Companion eval artifacts for the qwen3-4b-cot-compress-l1..l5
LoRA adapters. Evaluated on the full 1,319-question GSM8K test split.
Contents
pareto_summary.csv— accuracy + token-count summary, one row per level (incl. baseline = level 0).level_{0..5}/predictions.jsonl— per-question completions, parsed predictions, and correctness flags used to produce the summary.
How to read predictions.jsonl
Each row contains the question id, gold answer, full model completion,
and the parsed pred + correct fields used to compute the headline accuracy.
Important caveat on tokens. The baseline (level 0) does not emit
<think>...</think> blocks, so its token count is total_completion_tokens.
Levels 1–5 measure tokens inside the <think> block only. These are related
but not identical metrics — flag it in any downstream figure.
