v0.35.0

Decision models

Ollama now supports decision models through /v1/systemone, based on TypeSafe’s Jev API.

Decision models return choices, probabilities, and scores instead of text. Use them for tasks such as ticket triage, model routing, and content classification.

Available models:

• Nimble from Bespoke Labs
• Tev1 from Together AI

ollama pull nimble

Send context and one or more questions:

curl http://localhost:11434/v1/systemone \
  -H 'Content-Type: application/json' \
  -d '{
    "model": "nimble",
    "state": "Our checkout has returned 500 errors since 9am.",
    "questions": {
      "label": {
        "type": "choice",
        "instructions": "Which label fits this ticket?",
        "criteria": {
          "billing": "Payments and refunds",
          "bug": "Software errors",
          "account": "Login and account access"
        }
      }
    }
  }'

Example response:

{
  "model": "nimble",
  "answers": {
    "label": {
      "type": "choice",
      "choice": "bug",
      "probabilities": {
        "billing": 0.0125,
        "bug": 0.9781,
        "account": 0.0093
      },
      "confidence": 0.8906
    }
  },
  "usage": {
    "input_tokens": 174,
    "output_tokens": 1
  }
}

The API supports three question types:

• choice: Select an option and return probabilities for each.
• noul: Return the probability that a condition is true.
• score: Return a score across an ordered set of criteria

What's Changed

• Settings now opens without waiting for model discovery.
• Fixed the macOS update menu and icon not reflecting an available update at startup.
• Fixed stalled MLX model downloads hanging indefinitely.
• Requests containing the deprecated typical_p parameter now log a warning instead of failing.
