OpenAI Unveils o1-Pro, Its Most Powerful Reasoning Model to Date

OpenAI has introduced o1-pro, a new reasoning model designed to deliver stronger performance on complex tasks involving math, coding, and multi-step problem solving. The company says the model builds on its earlier o1 system with enhanced chain-of-thought processing, allowing it to work through difficult prompts with greater accuracy and consistency.

According to OpenAI, o1-pro outperforms previous versions on challenging benchmarks, making it its most capable reasoning model so far. The release is aimed at users who need more reliable results on advanced technical work, including developers, researchers, and teams handling demanding analytical tasks.

The model is now available to Pro and Team users, expanding access beyond earlier testing and rollout phases. OpenAI is also offering o1-pro through its API, with pricing set at $200 per million input tokens. The pricing reflects the model’s higher computational demands and its positioning as a premium tool for specialized use cases.

The launch underscores the growing competition among AI companies to improve reasoning performance, not just conversational fluency. As models become more capable at structured problem solving, they are increasingly being evaluated on how well they can support real-world workflows in software engineering, data analysis, and other high-stakes applications.
