### Providers

### Model Configuration (model_list)

> **What's New?** PicoClaw now uses a **model-centric** configuration approach. Simply specify `vendor/model` format (e.g., `zhipu/glm-4.7`) to add new providers—**zero code changes required!**

This design also enables **multi-agent support** with flexible provider selection:

- **Different agents, different providers**: Each agent can use its own LLM provider
- **Model fallbacks**: Configure primary and fallback models for resilience
- **Load balancing**: Distribute requests across multiple endpoints
- **Centralized configuration**: Manage all providers in one place

#### Basic Configuration

```json
{
  "model_list": [
    {
      "model_name": "ark-code-latest",
      "model": "volcengine/ark-code-latest",
      "api_key": "sk-your-api-key"
    },
    {
      "model_name": "gpt-5.4",
      "model": "openai/gpt-5.4",
      "api_key": "sk-your-openai-key"
    },
    {
      "model_name": "claude-sonnet-4.6",
      "model": "anthropic/claude-sonnet-4.6",
      "api_key": "sk-ant-your-key"
    },
    {
      "model_name": "glm-4.7",
      "model": "zhipu/glm-4.7",
      "api_key": "your-zhipu-key"
    }
  ],
  "agents": {
    "defaults": {
      "model": "gpt-5.4"
    }
  }
}
```

#### Vendor-Specific Examples

**OpenAI**

```json
{
  "model_name": "gpt-5.4",
  "model": "openai/gpt-5.4",
  "api_key": "sk-..."
}
```

**VolcEngine (Doubao)**

```json
{
  "model_name": "ark-code-latest",
  "model": "volcengine/ark-code-latest",
  "api_key": "sk-..."
}
```

**智谱 AI (GLM)**

```json
{
  "model_name": "glm-4.7",
  "model": "zhipu/glm-4.7",
  "api_key": "your-key"
}
```

**DeepSeek**

```json
{
  "model_name": "deepseek-chat",
  "model": "deepseek/deepseek-chat",
  "api_key": "sk-..."
}
```

**Anthropic (with API key)**

```json
{
  "model_name": "claude-sonnet-4.6",
  "model": "anthropic/claude-sonnet-4.6",
  "api_key": "sk-ant-your-key"
}
```

> Run `picoclaw auth login --provider anthropic` to paste your API token.

**Anthropic Messages API (native format)**

For direct Anthropic API access or custom endpoints that only support Anthropic's native message format:

```json
{
  "model_name": "claude-opus-4-6",
  "model": "anthropic-messages/claude-opus-4-6",
  "api_key": "sk-ant-your-key",
  "api_base": "https://api.anthropic.com"
}
```

> Use `anthropic-messages` protocol when:
> - Using third-party proxies that only support Anthropic's native `/v1/messages` endpoint (not OpenAI-compatible `/v1/chat/completions`)
> - Connecting to services like MiniMax, Synthetic that require Anthropic's native message format
> - The existing `anthropic` protocol returns 404 errors (indicating the endpoint doesn't support OpenAI-compatible format)
>
> **Note:** The `anthropic` protocol uses OpenAI-compatible format (`/v1/chat/completions`), while `anthropic-messages` uses Anthropic's native format (`/v1/messages`). Choose based on your endpoint's supported format.

**Ollama (local)**

```json
{
  "model_name": "llama3",
  "model": "ollama/llama3"
}
```

**Custom Proxy/API**

```json
{
  "model_name": "my-custom-model",
  "model": "openai/custom-model",
  "api_base": "https://my-proxy.com/v1",
  "api_key": "sk-...",
  "request_timeout": 300
}
```

**LiteLLM Proxy**

```json
{
  "model_name": "lite-gpt4",
  "model": "litellm/lite-gpt4",
  "api_base": "http://localhost:4000/v1",
  "api_key": "sk-..."
}
```

PicoClaw strips only the outer `litellm/` prefix before sending the request, so proxy aliases like `litellm/lite-gpt4` send `lite-gpt4`, while `litellm/openai/gpt-4o` sends `openai/gpt-4o`.

#### Load Balancing

Configure multiple endpoints for the same model name—PicoClaw will automatically round-robin between them:

```json
{
  "model_list": [
    {
      "model_name": "gpt-5.4",
      "model": "openai/gpt-5.4",
      "api_base": "https://api1.example.com/v1",
      "api_key": "sk-key1"
    },
    {
      "model_name": "gpt-5.4",
      "model": "openai/gpt-5.4",
      "api_base": "https://api2.example.com/v1",
      "api_key": "sk-key2"
    }
  ]
}
```

#### Migration from Legacy `providers` Config

The old `providers` configuration is **deprecated** but still supported for backward compatibility.

**Old Config (deprecated):**

```json
{
  "providers": {
    "zhipu": {
      "api_key": "your-key",
      "api_base": "https://open.bigmodel.cn/api/paas/v4"
    }
  },
  "agents": {
    "defaults": {
      "provider": "zhipu",
      "model": "glm-4.7"
    }
  }
}
```

**New Config (recommended):**

```json
{
  "model_list": [
    {
      "model_name": "glm-4.7",
      "model": "zhipu/glm-4.7",
      "api_key": "your-key"
    }
  ],
  "agents": {
    "defaults": {
      "model": "glm-4.7"
    }
  }
}
```

For detailed migration guide, see [docs/migration/model-list-migration.md](docs/migration/model-list-migration.md).

### Provider Architecture

PicoClaw routes providers by protocol family:

- OpenAI-compatible protocol: OpenRouter, OpenAI-compatible gateways, Groq, Zhipu, and vLLM-style endpoints.
- Anthropic protocol: Claude-native API behavior.
- Codex/OAuth path: OpenAI OAuth/token authentication route.

This keeps the runtime lightweight while making new OpenAI-compatible backends mostly a config operation (`api_base` + `api_key`).

**1. Get API key and base URL**

* Get [API key](https://bigmodel.cn/usercenter/proj-mgmt/apikeys)

**2. Configure**

```json
{
  "agents": {
    "defaults": {
      "workspace": "~/.picoclaw/workspace",
      "model": "glm-4.7",
      "max_tokens": 8192,

      "max_tool_iterations": 20
    }
  },
  "providers": {
    "zhipu": {
      "api_key": "Your API Key",
      "api_base": "https://open.bigmodel.cn/api/paas/v4"
    }
  }
