# Docto Decision Qwen3.5-4B (v0.1)

French medical decision models by Bofeng Huang: pass a patient message or clinical note, a question and candidate answers, and get one probability per answer from a single forward pass. Choice, score and noul. A research model, not a medical device.

A rank-16 LoRA merged into Qwen3.5-4B; the answer is one token (an option letter, or oui/non for noul). French only, up to 26 options. A research model, not validated clinically, and it can under-estimate urgency. Most benchmark labels come from Qwen teachers; on the gold-labelled tasks it scores 70.13% (ICD-10 chapter) and 60.94% (article specialty). Siblings: ModernBERT-fr-base (150M), Qwen3.5-0.8B and 2B, Gemma-4 E2B and E4B (all Apache-2.0) and MedGemma-1.5-4B (Google HAI-DEF terms). Trained on docto-decision-data-fr-v0.1 (943,013 records, 108 tasks).

## What it decides

- **choice** — picks one option from a set
- **score** — places the input on an ordered scale
- **noul** — answers a yes/no question with one probability
