Claude is provided by Anthropic and supports both text chat and image understanding. The mainstream Sonnet / Opus models natively support vision, so no separate Vision model needs to be specified.
All capabilities below can be configured in one place via the “Model Management” page in the Web Console, with no need to manually edit the configuration file.

​
Image Understanding

Once claude_api_key is configured, the Agent’s Vision tool automatically uses the Claude main model to recognize images, with no extra setup required. To manually specify a Vision model, set it explicitly in the configuration file: 
{
  "tools": {
    "vision": {
      "model": "claude-sonnet-4-6"
    }
  }
}
