What this is
An adapter rather than a full checkpoint. You need Qwen/Qwen3.5-4B-Base alongside it, and the licence of that base applies to you as well as this repository's own.
What we have not measured
Everything. We have not run this model on our frozen test split, so we have no accuracy, no calibration error and no risk and coverage curve for it. The facts on this page come from its own repository metadata, read on 20 September 2026, and are accurate as far as that goes and no further. The one model we have measured end to end is Jev.

A public number is a shortlist, not a decision
The only benchmark that settles which model you ship is one built from your own historical decisions. We freeze that test set, run the candidates against it, and hand back the threshold your error budget supports.
