OpenAI Joins Amazon Bedrock After New Agreement With Microsoft

OpenAI models are now available in limited preview through Amazon Bedrock, a platform for building generative artificial intelligence (AI) applications and agents.

As of Tuesday (April 28), Amazon Bedrock offers the latest OpenAI models, OpenAI’s Codex coding agent, and a new experience called Amazon Bedrock Managed Agents, powered by OpenAI, that is designed for building production-ready AI agents with OpenAI frontier models on Amazon Web Services (AWS), AWS said in a Tuesday press release.

These new offerings bring together OpenAI products and AWS infrastructure.

“Enterprises want to build with the most capable AI models and agents available,” AWS said in the release. “They also need the security posture, operational maturity and data governance that production workloads demand. Starting today, we are bringing those together with three new offerings, all in limited preview.”

In its own announcement that these products are available on Amazon Bedrock, OpenAI said that the models include its best frontier model GPT-5.5 and that the availability on AWS will enable customers to use the services, security controls, identity systems and procurement processes they already have in place.

This will allow developers more flexibility in how they build with OpenAI and provide enterprises with a single path from experimentation to production, the company said.

“Our strategic partnership with Amazon is focused on helping organizations deploy advanced AI at production scale,” OpenAI said in its announcement. “With OpenAI models, Codex and Managed Agents now coming to Amazon Bedrock, customers have a faster, more secure path to putting AI to work across their business.”

These announcements came a day after it was reported that OpenAI forged a new revenue and technology agreement with partner/AI competitor Microsoft that allows OpenAI to serve all its products to customers of any cloud provider.

While Microsoft will continue to have a license to OpenAI IP for models and products through 2032, the company’s license will now be non-exclusive.

When OpenAI announced on March 31 that it raised $122 billion in a funding round that valued it at $852 billion, the company said that the round was anchored by Amazon, Nvidia and SoftBank, and that there was continued participation from Microsoft.
