OpenAI is behind a recently announced $30 billion-a-year cloud deal with Oracle.

The generative AI company plans to rent around 4.5GW of capacity from Oracle, with the contract running through OpenAI's Stargate joint venture - of which Oracle is an investor.

Oracle will develop multiple data centers across the US with partners, Bloomberg reports. The existing Abilene, Texas, data center campus, built with partner Crusoe, could be expanded from 1.2GW to 2GW, while it is also evaluating other sites in Texas.

Other states being considered include Michigan, Wisconsin, Wyoming, New Mexico, Georgia, Ohio, and Pennsylvania, the Financial Times reports.

Alongside Oracle, OpenAI continues to use original backer Microsoft's Azure cloud extensively, as well as contracts with CoreWeave and Google - even using the latter company's custom TPUs.

At the same time, OpenAI is still planning to self-build its own data centers, the company's director of physical infrastructure told DCD in the latest issue of the magazine.

It also plans to develop a Stargate data center campus in the United Arab Emirates with Oracle, Nvidia, Cisco, SoftBank, and G42 involved. It is searching for sites for other projects across the world.
