A day after OpenAI decided to end its exclusive partnership with Microsoft, it has decided to offer its models through Amazon Web Services, CNBC reported on April 28.

AWS customers can now use OpenAI models and the Codex coding agent through Amazon Bedrock.

Amazon Bedrock is a fully managed AI services platform that lets users deploy various foundation models and large language models through a single API.

It supports companies in building and scaling generative AI applications more easily. Bedrock includes models from various companies, including Anthropic, but OpenAI's flagship models could not be listed on the Bedrock platform because of its contract with Microsoft.

After adjustments to its partnership agreement with Microsoft, OpenAI can now put its models on the Bedrock platform. As AWS is the world's largest cloud service, OpenAI can speed up its push into the enterprise market by entering Bedrock.

The two companies said OpenAI models and Codex will be offered on the Bedrock platform within weeks. Amazon Bedrock Managed Agents will also make it possible to develop custom agents with memory for previous interactions.

AWS Chief Executive Matt Garman said the collaboration with OpenAI was "something customers have been asking for a long time."

OpenAI's head of revenue, Denise Dresser (Denise Dresser), said in a memo sent to employees earlier this month, "The relationship with Microsoft was important, but it has limited our ability to reach customers on Bedrock, where many enterprises are."

The relationship between AWS and OpenAI appears to have been rapidly growing closer recently. OpenAI signed a $38 billion contract with AWS in November last year and, three months later, secured a $50 billion investment from Amazon. It also signed a supply contract for Trainium 2 chips for AI model training.
