OpenAI has released two new o-series reasoning models, namely o3 and o4-mini. The company said these are its first AI reasoning models to have built-in agentic abilities, allowing them to combine and use tools available within ChatGPT, such as web searching, file analysis, visual reasoning, and image generation. OpenAI noted that these models are trained to decide when and how to use these tools to generate detailed responses in the correct format.
