Ollama now supports Jev-style decision models

What changed

Ollama now supports Jev-style decision models September 29, 2026 Ollama now supports decision models, based on TypeSafe’s Jev API for fast, typed decisions: - No additional costs - Lower latency when run locally - Three new decision models available today via Ollama This new API is available as of Ollama 0.35 by using the new /v1/systemone endpoint. Send text as state with a set of named questions, and a model running on your machine answers them all in one request. This is great for tasks that require fast decisions, such as ticket triage, model routing, and content or safety moderation.

Why it matters

A concrete addition to Practical AI: Tools, Models & Frameworks: it changes what's available to builders today rather than being general commentary.
