Banger report on foundation decision models.
This is a AI post classified by AGK Intelligence as Open & local models (a model release), kept by the AI Radar because it carries real work, not commentary.
Banger report on foundation decision models. This work presents a 27B open decision model that lands within 1.6 points of Claude Opus 5.5 on Decision Bench v4 and answers in 183 ms instead of 3.5s. Nace AI released Drex, a family of four open decision models at 8B, 9B, 35B with 3B active, and 27B. You give the model a state, such as a document, a record, or an agent's context, plus questions with a fixed set of options. It returns a probability for each option without generating text. The 27B Max model scores 67.52 on the public Decision Index 0.4.1 suite, against 60.70 for Jev 1.14.0. On
