Microsoft lost its exclusivity as a cloud partner yesterday – today, AWS gets major OpenAI upgrade
GPT-5.5 and other models, including Codex, will be available for Amazon Bedrock customers
Available in limited preview for now, this is just the "beginning of a deeper collaboration"

A day after OpenAI revealed Microsoft would no longer be its exclusive cloud partner (but that it would still be a priority partner), the ChatGPT maker has announced a new deal with Amazon Web Services (AWS).

As part of the deal, GPT and other related models will be available on AWS via Amazon Bedrock for the first time, and the Codex agent can also be integrated into AWS environments.

This expansion comes weeks after Amazon announced a "multi-year strategic partnership" with OpenAI, which would see it invest $50 billion into the company.

OpenAI and AWS deepen their partnership

Under that deal, OpenAI would consume 2GW of Trainium capacity through AWS infrastructure, and the two companies would develop custom models together to power Amazon’s customer-facing applications. This eight-year agreement itself was an extension on a former agreement, worth a combined $138 billion.

The latest development puts OpenAI models straight into Bedrock alongside alternatives from Anthropic, Meta, Mistral, Cohere, Amazon and "other leading providers." It includes OpenAI's "best frontier model," GPT‑5.5.

By putting OpenAI's models straight into Bedrock, it means customers still have access to AWS enterprise features like IAM access controls, private networking, encryption, guardrails and AWS CloudTrail logging.

Amazon is especially pleased to be integrating Codex, noting its four million weekly users, noting its availability with the Codex CLI, the Codex desktop app and Visual Studio Code extension.

AWS described the latest news as just the "beginning of a deeper collaboration," and with Microsoft's exclusivity off the table, it could be the start of many more for OpenAI too.
