drex-max

Drex Max is the flagship 27B multimodal decision model from Nace.AI. Given a state (text, JSON or images) and typed questions (yes/no, multiple choice, or ordinal score), it returns a calibrated probability for every option in a single forward pass, with no text generation. It is TypeSafe System One compatible, handles contexts up to 262K tokens, and ranks #1 on Decision Index 0.3.2 with 67.59, ahead of Drex v2.0 and Jev 1.13.0.
