OpenAI announces availability across cloud providers

OpenAI and Microsoft are changing the terms of their partnership, ending exclusivity between OpenAI’s artificial intelligence models and Microsoft’s cloud offerings — as the AI developer announced new product availability through Amazon Web Services and other cloud providers.

In back to back announcements on Monday and Tuesday, OpenAI said its software will be eligible to operate on any cloud service provider, not just Microsoft. The Tuesday announcement confirmed OpenAI’s expanded partnership with AWS, with its models, Codex agentic software and agentic support for Amazon Bedrock all available to AWS customers. 

Microsoft will still be OpenAI’s primary cloud partner, however, and OpenAI products will be first available on Azure platforms unless Microsoft cannot “support the necessary capabilities,” per the press release. Microsoft will also stop paying a revenue share to OpenAI as part of the amended contract and will continue to have a license to OpenAI intellectual property through 2032. 

This move is meant to strengthen the companies’ “joint ability to build and operate AI platforms at scale while providing both companies the flexibility to pursue new opportunities,” the Monday press release said.

An AWS press release about the new OpenAI availability said the new capabilities on Amazon Bedrock “give customers the choice and flexibility to use the best models for their use case, on the world’s most broadly-adopted cloud.”

Coinciding with OpenAI’s new cloud distribution, the company announced that it had achieved FedRamp 20x Moderate authorization on Monday, making its products available via qualified cloud service providers for discretionary government workflows.

OpenAI’s slew of updates point to an expanded presence for a diverse customer base, particularly within the public sector.

Following the ongoing dispute between Anthropic and the Pentagon over how the company’s technology can be used, OpenAI’s announcements present the firm as an option to fill the void left behind by the government’s mandate to stop use of Anthropic’s Claude.

Microsoft and AWS are major players in the cloud computing space, with 2025 data from Synergy Research Group finding that AWS leads with 28% of the global market share among major cloud providers. The federal government is still heavily contracted with Microsoft, however, and its original partnership with OpenAI inked in 2023 enabled the company to route the AI products to its government customers.
