title: Claude
description: Anthropic Claude model configuration (Text Chat + Image Understanding)
---
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.
<Tip>
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.
</Tip>
## Text Chat
```json
{
"model": "claude-opus-4-8",
"claude_api_key": "YOUR_API_KEY"
}
```
| Parameter | Description |
| --- | --- |
| `model` | Supports `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](https://docs.anthropic.com/en/docs/about-claude/models/overview) |
| `claude_api_key` | Create one in the [Claude Console](https://console.anthropic.com/settings/keys) |
| `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-4-8` | Default recommended, latest flagship; best for complex reasoning and long-running tasks |
| `claude-opus-4-7` | Previous-generation Opus flagship |
| `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 |
## 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:
```json
{
"tools": {
"vision": {
"model": "claude-sonnet-4-6"
}
}
}
```
