router-expert-chemistry
LoRA expert for the chemistry target of the route-then-admit pool, trained on meirdick/router-experts-data data/experts/chemistry.jsonl.
- base:
Qwen/Qwen3-4B-Instruct-2507
- rank 16, alpha 32, dropout 0.05, modules q_proj, k_proj, v_proj, o_proj
- lr 0.0002, epochs 2, max_len 1024, token budget 8192 per batch
- one example per item per recipe (direct,cot_short), under the serving system prompt; 40% of the mc items re-lettered to 5 to 10 options
