(Reuters) -Microsoft ( MSFT )-backed OpenAI said on Thursday it was launching a series of AI models designed to spend more time processing to solve hard problems.

The models, dubbed o1 and o1-mini, can reason through complex tasks and solve harder problems than previous models in science, coding and math, the AI firm said.

The o1 will be available in ChatGPT and its API starting Thursday.

"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," OpenAI said.
