OpenAI Inc. is currently in talks to acquire the AI coding assistant for developers Windsurf, formerly known as Codeium, for nearly $3 billion, a source briefed on the talks told CNBC on Wednesday.

If the transaction with Windsurf goes through, this would be OpenAI's largest acquisition in an attempt to stay at the forefront of the generative AI race, competing with key rivals such as Anthropic, Elon Musk's xAI and Google.

Earlier in the day, OpenAI launched its latest AI models, o3 and o4-mini "reasoning models," which are "trained to think for longer before responding."
