Ollama Release Notes

What's Changed

Models run on MLX on Apple Silicon by default

In this release, on Apple Silicon devices, model architectures supported by the MLX runtime will automatically run on MLX.

ollama pull qwen3.8
ollama run qwen3.8

Additional models include gemma4, qwen3.6 and qwen3.5

Decision models are now available on MLX as well: Nimble tev1 clef clef-flash

MLX now has support for an embedding model: embeddinggemma-2

We will continue testing and enabling additional models.

Full Changelog: v0.35.1...v0.40.0

Clef decision models

Ollama now supports Clef and Clef Flash, Cloudflare's new open-source decision models, through /v1/systemone.

Clef (27B) and Clef Flash (9B) are multimodal: requests can now include images alongside the text state, shared by all questions and scored jointly with it.

curl http://localhost:11434/v1/systemone -d '{
"model": "clef-flash",
"state": "The user took this screenshot.",
"images": ["<base64-encoded image>"],
"questions": {
"has_ollama": {"type": "noul", "instructions": "Does this image contain Ollama?"}
}
}'

{
"model": "clef-flash",
"answers": {
"has_ollama": {
"type": "noul",
"noul": 0.958
}
},
"usage": {
"input_tokens": 548,
"output_tokens": 0
}
}

What's Changed

Models using web search can now perform up to ten searches per response, up from three

Modelfiles now support CAPABILITY declarations, so model creators can explicitly declare what a model can do. Declarations are preserved when creating from GGUF or safetensors, through model inheritance, and on Modelfile export

ollama show and the model list now report only decision as the capability for decision models, so clients no longer offer them for general chat, tools, or thinking

Updated llama.cpp and the MLX engine

Full Changelog: v0.35.0...v0.35.1

Add CAPABILITY declarations to Modelfiles and an additive capabilities field to create requests. Preserve declarations across GGUF and safetensors creation, inheritance, and Modelfile export.

Require decision capability before scheduling System One requests instead of matching Qwen architecture/renderer metadata. Retain main's GGUF-only scoring restriction until the separate MLX runtime work lands.

Extracted from the capability foundation in 36d46a0 on system_one_mlx; MLX scoring and manifest-list changes are intentionally separate.

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.

Full Changelog: v0.34.4...v0.35.0

Add manifest-list storage so runner-specific manifests can coexist under one tag while preserving existing v1 tags as best-effort downgrade anchors. Show/list/copy/remove/pull/push now understand runner and digest selection and transfer referenced child manifests and layers.

Add lazy local compatibility migration for legacy Ollama GGUFs into llama.cpp-compatible children, covering the patched model families and preserving parser/renderer, templates, projectors, media metadata, split GGUFs, and MTP/draft tensors where applicable.

Extend create/import/conversion paths for the same compatibility rules, harden manifest-list combine validation, and add focused manifest, migration, transfer, and integration coverage for first-load conversion plus chat/tools/vision/audio/embedding behavior.
