Decisio
Decisions you can trust, on your own hardware. Open source.
Decisio is an open-source server that answers typed questions about any text, with a calibrated probability for every option, from one forward pass and no generated text.
On JevBench v1.6.1 (the board’s file, October 2026), Decisio 31B scored 71.69 on the composite (95% interval 69.86 to 72.81) and Jev 1.13.0 scored 71.49 (69.14 to 72.40); the two intervals overlap. The live board is at https://benchmarkheaven.com/jev-models and has moved since. (JevBench v1.6.1, decisio on Gemma 4 31B; how we read the board.)
