Qwen3.5-2B-metro-v24

QLoRA fine-tune of Qwen3.5-2B for the MetroLLM-Bench transit-kiosk task. v24 is the leakage-free retraining used in the MetroLLM-Bench paper (teacher traces drawn only from the 717-case training partition; 238 cases held out). Supersedes continker/Qwen3.5-2B-metro-v23.

Held-out results (n=238, mean of 2 seeds)

Metric 2B base 2B + v24 Δ
Tier-1 74.17 79.43 +5.26
Composite 71.90 77.93 +6.03

The largest relative PEFT gain on the size curve. At 1.2 GB Q4_K_M it runs on a fanless laptop (~39 tok/s sustained on an M2 Air).
