The decision model directory

How to read this

Decision models went from one product to a whole shelf in about five days. Jev shipped on 15 September 2026; every open-weight model below was published within the week. Nothing that recent has been checked by anyone outside the people who trained it, which is the entire reason this directory grades evidence instead of ranking models.

Benchmarked means we ran it ourselves on a frozen test split and published the numbers with confidence intervals. Community means the facts below are read from the model’s public card, with the date they were read. We would rather leave a field blank than fill it from a press release.
