Ollama 0.35.0 introduces support for "decision models" through a new `/v1/systemone` API, based on TypeSafe's Jev API. Instead of free-form text, these models return structured choices, probabilities, and confidence scores — useful for ticket triage, model routing, and classification. Ships with Bespoke Labs' Nimble and Together AI's Tev1. Supports `choice`, `noul`, and `score` question types.

capability delta

An agent can now call Ollama's /v1/systemone endpoint with a state and typed questions to get back structured choices with probabilities and confidence scores — enabling deterministic routing, triage, and classification without parsing LLM text.

curator note

New endpoint (`/v1/systemone`) plus two new decision-model families (Nimble, Tev1). Clear agent-relevant capability for routing/triage. Note "noul" appears to be a typo in the release notes (likely "bool").
