OpenAI has released o1-pro, an upgraded version of its o1 reasoning model that the company says delivers stronger performance on demanding tasks in mathematics, coding and science. The new model is designed to handle complex, multi-step problems with improved chain-of-thought reasoning, making it better suited for advanced analytical work and PhD-level questions.
According to OpenAI, o1-pro outperforms earlier models, including GPT-4o, on a range of benchmark tests. The launch marks another step in the company’s push to expand the capabilities of its reasoning systems, which are increasingly being positioned as tools for deeper problem-solving rather than just conversational assistance.
The model is now available to ChatGPT Pro and Team users, as well as through OpenAI’s API. That broader access is expected to make o1-pro attractive to developers, researchers and businesses looking for higher-quality outputs on technical and scientific tasks.
The release also raises the stakes in the fast-moving AI race, where rivals such as Anthropic and Google are continuing to improve their own advanced reasoning models. As competition intensifies, performance on difficult benchmarks and real-world problem solving is becoming a key differentiator among leading AI systems.
