Ollama v0.35.1
Clef and Clef Flash, Cloudflare’s open-source decision models, run locally.
Release notes, ollama/ollama v0.35.1
Part 01

Ollama v0.35.1 adds Clef and Clef Flash, Cloudflare's new open-source decision models. Both answer through the System One endpoint, and both are in the Ollama library.

Clef is 27B and Clef Flash is 9B

Ollama
Ollama
v0.35.1

Two sizes, one endpoint

27B
Clef Flash
9B
Release notes, ollama/ollama v0.35.1
Part 01

They come in two sizes. Clef is the larger model, at 27 billion parameters. Clef Flash is the smaller one, at 9 billion, and it's the model in the release example.

Decision requests can now include images

Ollama
Ollama
v0.35.1
"model": "clef-flash",
"state": "The user took this screenshot.",
"images": ["<base64-encoded image>"],
Images need Clef or Clef Flash with vision weights, sent as base64.
Release notes · docs/openapi.yaml
Part 01

Both models are multimodal. A request can send images alongside the text state, and each question is scored against both together. Images need Clef or Clef Flash with vision weights.

Clef Flash is 96 percent sure the screenshot shows Ollama

Ollama
Ollama
v0.35.1

The answer is one probability

"has_ollama": {
  "type": "noul",
  "noul": 0.958
}
Release notes, ollama/ollama v0.35.1
Part 01

In the release example, Clef Flash is asked whether a screenshot contains Ollama. It answers with a probability of 0.958, so it is about 96 percent sure the answer is yes.

Decision models now report only the decision capability

v0.35.1

Decision models now report only decision

Clients stop offering them for general chat, tools or thinking.
Release notes, ollama/ollama v0.35.1
Part 02

In the model list and in Ollama show, a decision model now reports a single capability: decision. Apps built on Ollama stop offering these models for chat, tools or thinking.

Modelfiles can declare a CAPABILITY

Ollama
Ollama
v0.35.1
The declaration survives GGUF and safetensors imports, inheritance and Modelfile export.
Release notes · docs/modelfile.mdx
Part 02

Model creators can now state what a model can do with a new capability instruction in the Modelfile. It carries through GGUF and safetensors imports, inheritance, and export.

Ten web searches per response, and updated engines
