GPT-5.6 Sol Pro is OpenAI's GPT-5.6 Sol model configured with pro-mode reasoning for more rigorous problem-solving on complex tasks.

Strengths

Handles complex reasoning tasks with extended thinking enabled at the pro level, providing more thorough analysis and higher-quality outputs.

Best for

Multi-step reasoning problems, research synthesis, and tasks requiring careful deliberation where extra computation time is justified.

Limitations

Pro-mode reasoning increases latency and token usage compared to standard reasoning modes, and works best with sufficient context for complex queries.
