OpenAI has released o1 and o1-mini, the first in a series of reasoning models that have been trained to answer more complex questions faster than a human can. The model is better at writing code and solving multistep problems than previous models, but it is more expensive for developers and slower to use than GPT-4o. The release is still in preview to indicate how nascent it is. ChatGPT Plus and Team users should already have access to the model, while Enterprise and Edu users will get access early next week. OpenAI plans to bring o1-mini access to all free users, but it hasn't set a release date yet.
This guide was missed in the excitement of OpenAI's new reasoning models. It shows how prompting this new model is different and requires simpler prompts and a more structured input context.
