Claude - CowAgent

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.

Text Chat

{
  "model": "claude-opus-5-5",
  "claude_api_key": "YOUR_API_KEY"
}

Parameter	Description
`model`	Supports `claude-opus-5-5`, `claude-opus-5`, `claude-sonnet-5`, `claude-fable-5-1`, `claude-fable-5`, `claude-opus-4-8`, `claude-opus-4-7`, `claude-sonnet-4-6`, `claude-opus-4-6`, `claude-sonnet-4-5`, `claude-sonnet-4-0`, `claude-3-5-sonnet-latest`, etc. See official models
`claude_api_key`	Create one in the Claude Console
`claude_api_base`	Optional, defaults to `https://api.anthropic.com/v1`. Can be changed to a third-party proxy

Model Selection

Model	Use Case
`claude-opus-5-5`	Latest flagship; default recommendation, best on complex reasoning and long-running Agent tasks
`claude-opus-5`	Previous Opus flagship
`claude-sonnet-5`	Balanced option in the Claude 5 family; good reasoning quality at a lower price
`claude-fable-5-1`	Alternative flagship in the Claude 5 family (newer revision)
`claude-fable-5`	Alternative flagship in the Claude 5 family
`claude-opus-4-8` / `claude-opus-4-7`	Earlier Opus flagships
`claude-sonnet-4-6`	Balanced cost and speed, lower cost
`claude-opus-4-6` / `claude-sonnet-4-5` / `claude-sonnet-4-0`	Earlier flagships at a lower price

Thinking Mode

Controlled by the global enable_thinking setting, which can also be toggled on the Web Console configuration page. When enabled, the Web Console shows the thinking process:

{
  "enable_thinking": true,
  "reasoning_effort": "high"
}

reasoning_effort sets the thinking intensity (mapped to Anthropic’s output_config.effort) and accepts low / medium / high / xhigh / max, with the supported range depending on the model. It only takes effect when enable_thinking is true.

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-5"
    }
  }
}
