Original GitHub issue: https://github.com/ollama/ollama/issues/10027

What is the issue?

After updating to version 1.0.5 I got an error message when loading. I have a large config.yaml which has grown over time, with lots of old/unnecessary or possibly outdated stuff in it. Because of this, every model had tools enabled (I never checked each one to see if they actually supported tools)

The error is caused by values this value in the yaml. In the cases I showed, those 2 models will fail because of
capabilities: - tools_use

Removing that from the yaml will allow it to load.

Here are 2 examples where it fails.

schema: v1
version: 1.0.0


models:

  - name: gemma3:27b
    provider: ollama
    model: gemma3:27b
    apiBase: http://127.0.0.1:11434
    defaultCompletionOptions:
        maxtokens: 4056
        temperature: 0.2
        topP: .2
    capabilities:
      - tools_use
    roles:
      - chat

  - name: qwen2.5:32b
    provider: ollama
    model: qwen2.5:32b
    apiBase: http://127.0.0.1:11434
    defaultCompletionOptions:
        maxtokens: 8000
        temperature: 0.2
        topP: .2
    capabilities:
      - tools_use
    roles:
      - chat
    ```

Doesn't appear to be an ollama issue. ollama does't parse YAML files for configuration.
