Who is SOTA in Decision models?

As of Oct 14, 2026, vLLM-SR d3 (27B) & linne-oak 1.0 (31B) & Perplexity Decider v1.1 27B (Qwen3.8-27B, noncausal decision readout) are tied for state of the art with low confidence in Decision models (since Oct 14, 2026; sources Decision Index Full and JevBench; methodology v1.0).

Since when is the Decision models crown current?

The current crown in Decision models has held since Oct 14, 2026.

What is a decision model?

A decision model takes state, as text or as images, plus a typed question. It returns a typed answer with probabilities rather than free text. Output types: noul (yes/no/unknown), choice, score, multi-label.

How is calibration ranked?

The calibration slice ranks the lowest ECE among models in the top quartile of accuracy, so a constant probability cannot take the slice. Brier breaks ECE ties.

Do vendor-reported decision numbers count?

Vendor-reported numbers are display-only at weight 0.
