About GPT 5.6 Sol
GPT 5.6 Sol is OpenAI's flagship reasoning model in the GPT 5.6 family, optimized for complex mathematics, programming, and scientific research. It accepts mixed text and image inputs, supports a system prompt to steer behavior, and can call an integrated web search tool for real-time information. Reasoning depth is adjustable via the reasoning_effort parameter, up to 'xhigh' for the most demanding logic problems. Sol delivers the deepest reasoning in the family, sitting above the speed-optimized [Luna](/playground/gpt-5-6-luna) and the balanced [Terra](/playground/gpt-5-6-terra) model.
