# Drex Max

Drex turns choosing into a single forward pass: given a context, a question and a set of options, the model returns a probability for every option instead of parsing text written by a large model. Drex Max, the largest of four open decision models, scores 67.52 on the public Decision Index 0.4.1 suite against 60.70 for Jev 1.14.0, and drops less than a point when private tests are added. On Decision Bench v4 with raw image input it is statistically tied with d3-turbo and GPT-6 Sol, answering a typical request in 183 ms.

Nace released Drex Max, a decision model that reads screenshots, screencasts, scanned documents, charts or photos and, given a set of typed questions, returns a probability for every supplied option in one forward pass. A computer-use agent can face about thirty such small decisions in a single task, and each one previously meant sending a screenshot to a large frontier model and waiting seconds; Drex Max scores 67.6 on the public Decision Index 0.4.0 against 61.3 for Drex v2.0, with a median API latency of 183 ms and $0.06 per 1,000 decisions.
