Our take
Written Sep 5, 2026o1-pro is OpenAI's premium reasoning model, built for complex multi-step problems rather than quick chat. It handles up to 200,000 tokens in a single request and accepts text, images and files, though it comes at a steep price with no measured quality data yet.
Choose this when you need OpenAI's most capable reasoning on documents, images or files up to 200,000 tokens, and where output quality justifies premium pricing for deep analysis or complex problem-solving. Skip it if cost matters, if you need fast responses, or if you want verified benchmark scores to guide your choice.
The case for it
- Extremely long context for a reasoning model: up to 200,000 tokens in a single request.
- Accepts text, images and files, making it suitable for multimodal analysis tasks.
The case against it
- Very expensive relative to typical text models, with no cheaper alternative in our data.
- Slow throughput on OpenAI's own infrastructure: 8 tokens per second.
- No measured quality scores in our data, so there is no independent verification of its capabilities.
How good is it?
We hold no score for this model.
So there is no figure here for everyday use, coding, agent work or writing. That is a gap in our data, not a low score.
