# proposal-cot-sft Qwen2.5-32B LoRA (V2)

LoRA adapter for Qwen2.5-32B-Instruct fine-tuned on `arxiv-proposal-cot-sft-32b-v2`
(928 CoT examples, `with_research_question` conditioning, 16k sequence length).

- **Recipe:** LoRA r=64, α=128, all-linear; lr 1e-5 cosine (warmup 0.03), wd 0.01; effective batch
  128 (8×H800); 1 epoch; bf16; verl FSDP SFT trainer. Train time ≈49 min.
- **Behavior:** generates `<thinking>` + a 10-tag XML research proposal from a reading-list prompt.
  Schema-complete and reference-grounded on held-out papers.
- **Honest result:** on a 10-task implementation benchmark the SFT model matched but did not beat
  base pass-rate (base 1/10 vs SFT 0/10; several raw metrics improved). Released as a documented
  baseline for creativity-distillation research (the project's V3 direction).
- Apply with PEFT on top of `Qwen/Qwen2.5-32B-Instruct` (Apache-2.0), or use the optional merged
  weights repo. Code + eval harness: https://github.com/XinghanLi66/autoresearch_idea_harness
