About GPT-o1

GPT-o1 is OpenAI's first dedicated reasoning model, introducing the concept of 'thinking tokens' where the model reasons through problems step-by-step before generating a response. This approach significantly improves performance on complex mathematics, coding challenges, and scientific reasoning compared to standard language models. With a 200K token context window, o1 can process lengthy technical documents while applying deep reasoning. It excels on competition-level math problems, PhD-level science questions, and complex coding tasks that require careful logical thinking. While slower and more expensive than GPT-4o due to the reasoning overhead, o1 delivers substantially better results on tasks that benefit from deliberate, structured problem-solving rather than quick pattern matching.

How much does GPT-o1 cost?
GPT-o1 costs $15.00 per 1M input tokens and $60.00 per 1M output tokens. You pay only for what you use, which keeps costs predictable.
What is GPT-o1's context window?
GPT-o1 has a context window of 200K tokens. This determines how much text the model can process in a single request — bigger windows mean longer documents and richer conversation history.
Is GPT-o1 open source?
No, GPT-o1 is a proprietary model available through OpenAI's API. You get managed infrastructure, regular updates, and support as part of the package.
What is GPT-o1 best for?
GPT-o1 is best suited for: Complex reasoning, math, science, coding. These use cases play to the model's strengths in capability, speed, and cost within OpenAI's lineup.
