GPT-6 Sol Pro
openai/gpt-6-sol-proGPT-6 Sol Pro is the same GPT-6 Sol model, the middle tier of OpenAI's GPT-6 family, served in OpenAI's pro reasoning mode rather than as a separate model. Pro mode does more model work on each request before returning a single final answer, which OpenAI suggests for difficult coding, review and deep analysis where quality outweighs speed. It adds latency and token usage compared with standard GPT-6 Sol, and OpenAI's docs point to GPT-6.1 Sol as the updated Sol model.
