Models

The Cline API gives you access to models from multiple providers through a single endpoint. Model IDs follow the provider/model-name format, the same convention used by OpenRouter.

Model ID Format

Every model is identified by a string in the format:

provider/model-name

For example:

• anthropic/claude-sonnet-4-6 - Claude Sonnet 4.6 from Anthropic
• openai/gpt-4o - GPT-4o from OpenAI
• google/gemini-2.5-pro - Gemini 2.5 Pro from Google

Pass this string as the model parameter in your Chat Completions request.

Example:

curl -X POST https://api.cline.bot/api/v1/chat/completions \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "minimax/minimax-m2.5",
    "messages": [{"role": "user", "content": "Hello!"}]
  }'

Reasoning Models

Some models support extended thinking, where the model reasons through a problem before responding. When using these models:

• Reasoning content appears in delta.reasoning during streaming
• Some providers return encrypted reasoning blocks in delta.reasoning_details
• Reasoning tokens are counted separately from output tokens

Models with reasoning support include most Claude, Gemini 2.5, and Grok 3 models. Check the model's supportsReasoning capability in the model catalog.

Choosing a Model

For a deeper comparison of model capabilities and pricing, see the Model Selection Guide.

Image Support

Models that support images accept base64-encoded image content in the messages array:

{
  "model": "anthropic/claude-sonnet-4-6",
  "messages": [
    {
      "role": "user",
      "content": [
        {"type": "text", "text": "What's in this image?"},
        {"type": "image_url", "image_url": {"url": "data:image/png;base64,..."}}
      ]
    }
  ]
}

Not all models support images. Check the model's supportsImages capability before sending image content.
