OpenAI is planning to use Google Cloud's computing capacity, according to sources.

As reported by Reuters, despite Google's position as an AI rival to OpenAI, the company is planning to use Google Cloud Platform to meet its computing needs and further diversify its resources.

Reuters cites "three sources," noting that the collaboration is a surprising agreement between the competitors, with Google's DeepMind AI unit being in direct competition, and ChatGPT posing a threat to Google's search business.

Google will provide OpenAI with additional computing capacity to help OpenAI train and run its AI models, the sources said. It is unclear if OpenAI will be using Google's in-house tensor processing units (TPUs), or if it will be using the cloud platform to solely access GPU capacity.

OpenAI, Google, and Microsoft declined to comment to Reuters.

Previously, Microsoft was OpenAI's exclusive cloud provider due to its early heavy investment in the company. However, as compute capacity demand for OpenAI has continued to grow, it is now diversifying beyond Microsoft.

The AI company announced its $500bn Stargate project at the start of this year in partnership with SoftBank, Oracle, and Abu Dhabi's MGX. The first campus will be in Abilene, Texas, for which Oracle is supposedly set to purchase around 400,000 Nvidia GB200s.

Beyond the US, OpenAI is exploring developing Stargate campuses in other locations, including in the UAE, and OpenAI’s chief strategy officer is currently touring Asia Pacific, including India, Japan, South Korea, Australia, and Singapore - with the trip in part to hear potential data center investment incentives. In Europe, OpenAI is reportedly in discussions with the UK, France, and Germany.

OpenAI also signed a $4bn cloud deal with CoreWeave in May 2025, building on an earlier $11.9bn deal with the neocloud.

This week, financial services firm TD Cowen said that it believed Oracle was seeking around 5GW of data center capacity in the US for OpenAI, separate from the Stargate project.

According to Reuters' sources, OpenAI had previously sought a deal with Google Cloud but was blocked by its lock-in with Microsoft.
