OpenAI plans to buy Google’s AI chips

OpenAI is one of the largest buyers of Nvidia’s graphics processing units, or GPUs, which the ChatGPT maker uses to train AI models and run inference computing.

Reuters reported in June 2025 that OpenAI had begun renting Google’s AI chips.

Google’s Tensor Processing Units, or TPUs, have gained traction as an alternative to Nvidia’s market-leading AI chips as companies seek cheaper options and chips suited to running AI models. Google began selling TPUs directly to some customers this year.
