Introducing OpenAI o3 and o4-mini—our smartest and most capable models to date.
For the first time, our reasoning models can agentically use and combine every tool within ChatGPT, including web search, Python, image analysis, file interpretation, and image generation.
We’re cutting the price of o3 by 80% and introducing o3-pro in the API, which uses even more compute.
o3:
Input: $2 / 1M tokens
Output: $8 / 1M tokens
Now in effect.
We optimized our inference stack that serves o3. Same exact model—just cheaper.

OpenAI has released o3, their highly anticipated reasoning model, along with o4-mini, a smaller and cheaper model that succeeds o3-mini.
We evaluated the new models on our suite of math and science benchmarks. Results in thread!
