Another season, another OpenAI model. On September 12, the AI developer announced a new generative AI model series called OpenAI o1—unofficially and colloquially known as Strawberry— that improves its accuracy by reasoning first before responding to a problem or prompt.

“We trained these models to spend more time thinking through problems before they respond, much like a person would,” OpenAI said in a blog post introducing OpenAI o1. “Through training, they learn to refine their thinking process, try different strategies, and recognize their mistakes.”
