Drex v2.0 is a 35B mixture-of-experts decision model (3B active) from Nace AI, the larger successor to Drex v1.5. Send application state (text or JSON) and typed questions (noul / choice / score) and get back a calibrated probability for every answer option in a single forward pass, with no text generation. It is TypeSafe System One compatible and suits routing, classification and policy checks that need a scored answer instead of prose. Call POST /api/v1/decisions (POST /api/v1/systemone is the same handler).
