ChatGPT Pro is more than just an assistant – it’s your intelligent partner for boosting productivity, creativity, and efficiency every day. Powered by the cutting-edge GPT modeling technology from OpenAI, this app transforms the way you work, learn, and engage with technology.
More thinking power for more difficult problems
ChatGPT Pro provides access to a version of our most intelligent model that thinks longer for the most reliable responses. In evaluations from external expert testers, o1 pro mode produces more reliably accurate and comprehensive responses, especially in areas like data science, programming, and case law analysis.
Compared to both o1 and o1-preview, o1 pro mode performs better on challenging ML benchmarks across math, science, and coding.

To highlight the main strength of o1 pro mode (improved reliability), we use a stricter evaluation setting: a model is only considered to solve a question if it gets the answer right in four out of four attempts ("4/4 reliability"), not just one.

Pro users can access this functionality by selecting o1 pro mode in the model picker and asking a question directly. Since answers will take longer to generate, ChatGPT will display a progress bar and send an in-app notification if you switch away to another conversation.
