OpenAI unveils new series of AI models with ‘reasoning’ abilities

Microsoft-backed (NASDAQ:MSFT) OpenAI has introduced a new series of AI models designed for solving harder problems.

Called o1 and o1-mini, these new models can reason through complex tasks and solve harder problems than previous models in science, coding, and math.

“We trained these models to spend more time thinking through problems before they respond, much like a person would. Through training, they learn to refine their thinking process, try different strategies, and recognize their mistakes,” the company said.

OpenAI o1 is a new large language model trained with reinforcement learning to perform complex reasoning. An early version of this model, OpenAI o1-preview, will be available for immediate use in ChatGPT and to trusted API users.

OpenAI o1-mini is a faster, cheaper reasoning model that is particularly effective at coding. “As a smaller model, o1-mini is 80% cheaper than o1-preview, making it a powerful, cost-effective model for applications that require reasoning but not broad world knowledge.”

ChatGPT Plus and Team users will be able to access o1 models in ChatGPT starting today. Both o1-preview and o1-mini can be selected manually in the model picker, and at launch, weekly rate limits will be 30 messages for o1-preview and 50 for o1-mini.

The company said it is working to increase those rates and enable ChatGPT to automatically choose the right model for a given prompt.
