OpenAI has announced that their frontier models and Codex are now on Amazon Web Services. This allows enterprises to bring OpenAI capabilities into AWS environments with the controls their teams already trust, helping shorten the time from evaluation to real deployment.
OpenAI on AWS will work two ways — with “OpenAI on Bedrock” which allows teams to build AI applications using AWS-native security and governance controls, and with “Codex on Amazon Bedrock,” which brings OpenAI’s leading software engineering agent into AWS, helping teams write, review, debug, and modernize code in the environments where they already build and ship.
“As customers begin using these capabilities, the AWS path helps reduce friction around procurement, security review, and production readiness. By making OpenAI capabilities available within familiar AWS environments, organizations can spend less time navigating operational barriers and more time building,” OpenAI said.

OpenAI says this development is the start of a broader path for customers to bring frontier AI into the environments where they already build, govern, and ship. The company plans to continue expanding capabilities available through AWS so that it is easier for teams to move from evaluation to production.
This includes future availability for Daybreak, OpenAI’s vision for changing how software is built and defended.
Daybreak, which includes cyber models and Codex Security has been designed to help see risks earlier, act sooner, and make software more resilient by bringing secure code review, threat modeling, patch validation, dependency risk analysis, detection, and remediation guidance into the everyday development loop.
OpenAI also states that AWS can provide an important path for security teams to adopt specialized capabilities like Daybreak using the security, governance, procurement, and operational frameworks they already use.

This comes amid OpenAI’s increased collaboration with Amazon, which has been seen by some as a drift away from its partner, Microsoft. Earlier this year, it was reported that Microsoft is considering legal action against the ChatGPT-maker, claiming its deals with Amazon could potentially violate its exclusivity agreement.
The reports claim there was a dispute over whether OpenAI can offer Frontier via AWS without violating the Microsoft partnership, which requires the startup’s models to be accessed through the Windows-maker’s Azure cloud platform. OpenAI revenue chief Denise Dresser said that the decision to make its models available on Amazon was unrelated to the restructuring of its relationship with Microsoft happening around the time it was announced.
