OpenAI has expanded its latest AI models, o1-preview and o1-mini, to ChatGPT Enterprise and Edu customers, offering advanced reasoning capabilities for complex problem-solving in business and education.

Last week, OpenAI released “o1,” a new AI model that can reason through hard problems by breaking them down to their component parts and handling them step by step. Released in two iterations, o1-preview and o1-mini, the model is available to all ChatGPT Plus users, with a broader release to follow.

ChatGPT maker OpenAI has announced a model that can effectively fact-check itself by "reasoning" through questions.

OpenAI is releasing a new model called o1, the first in a planned series of “reasoning” models that have been trained to answer more complex questions, faster than a human can. It’s being released alongside o1-mini, a smaller, cheaper version. And yes, if you’re steeped in AI rumors: this is, in fact, the extremely hyped Strawberry model.

OpenAI's new o1 model uses the chain of thought reasoning to improve the response in complex tasks. It brings a paradigm shift in inference scaling.
