OpenAI: GPT-5.6 Sol

GPT-5.6 Sol is OpenAI's flagship GPT-5.6 model for complex professional work, advanced reasoning, coding, research, agentic workflows, and multimodal understanding. It combines a 1.05M-token context window with deep reasoning, structured outputs, function calling, computer use, web and file search, code execution, MCP, and long-horizon tool-driven workflows.

Code Example

curl ${API_BASE_URL}/v1/chat/completions \
  -H "Authorization: Bearer <YOUR_API_KEY>" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "gpt-5.6-sol",
    "messages": [
      {
        "role": "user",
        "content": "Hello"
      }

Supported Parameters

ParameterTypeDefaultDescription
stringmediumControls reasoning depth. Lower levels reduce latency and reasoning-token usage, while higher levels provide deeper reasoning for complex tasks.
stringstandardControls the reasoning execution mode. Pro mode applies more model work for difficult quality-first tasks and may increase latency and token usage.
integer128000Controls the maximum number of output tokens.

Rate Limits

GroupRPMTPMRPD

RPM = requests per minute, TPM = tokens per minute, RPD = requests per day. Limits apply by token group.
