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 would consume 2GW of Trainium capacity through AWS infrastructure, and the two companies would develop custom models together to power Amazons 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," GPT5.5.

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.

Codex on Bedrock, as well as the availability of OpenAI models and Amazon Bedrock Managed Agents powered by OpenAI, are all available in limited
