Scores

Trained with assistant-only loss masking on recombined, decontaminated BÍN data. Masking is what lets a reasoning base absorb morphology without losing coherent chat.
Run it with thinking disabled. The base is a reasoning model, but this variant answers directly and scores lower with thinking on. Use apply_chat_template(..., enable_thinking=False); do not hand-edit the template.
Provenance
The weights carry a canary-mixed instructional fingerprint: a private trigger produces a fixed signature response. It is verified to fire while leaving inflection and chat quality intact. The trigger is not published, and is used to prove origin if these weights turn up elsewhere.
Use
transformers or vLLM, with the model's chat template.
