| Summary | o1-pro is OpenAI's highest-compute variant of the o1 reasoning model, designed to spend more inference-time compute 'thinking harder' before responding. It targets difficult reasoning tasks — complex analysis, math, and coding — where accuracy matters more than speed or cost. | OpenAI reasoning model focused on hard problems. |
