Ollama 0.35 now supports the Jev‑style decision model API. Users can call the new /v1/systemone endpoint, send a text state and a set of named questions, and get structured answers in one request. Three models are available immediately: Nimble 9B, Tev1 4B, and Tev1 0.8B.

Running locally removes network latency; Nimble 9B averages 91 ms per decision on an M5 Max MacBook. The models work with curl or TypeSafe’s Python SDK.

## The facts

- Release date: September 29 2026
- Three decision models launched: nimble (9B), tev1 (4B), tev1:0.8b (0.8B)

## Why it matters

Local decision models give instant, low‑cost classifications for tasks like ticket routing or content moderation.
