Model Recommendations

For Speed

gemini-3-flash - Fastest responses, great for autocomplete and quick tasks.

For Quality

claude-sonnet-4-5-thinking - Best reasoning capabilities with extended thinking.

For Long Context

gemini-2.5-pro - 1M token context window for large codebases.

For Budget

gemini-2.5-flash-lite - Lower resource usage, good for simple tasks.

Thinking Models

Models with "thinking" support (marked with ✓) can show their reasoning process. This is useful for:

• Complex problem solving
• Step-by-step explanations
• Debugging logic errors

When using thinking models, the gateway properly handles the extended thinking format and streams thought content to compatible clients.

Checking Your Available Models

# JSON format
