OpenAI brings frontier models and Codex to AWS through Amazon Bedrock
OpenAI frontier models and Codex are now generally available on AWS
OpenAI frontier models and Codex are now generally available on Amazon Web Services, giving AWS customers access to OpenAI capabilities through the cloud infrastructure many already use for security, compliance, billing, procurement, and deployment.
The rollout gives enterprises two routes into OpenAI on AWS. OpenAI models are available on Amazon Bedrock for teams building AI applications with AWS-native security and governance controls, while Codex on Amazon Bedrock brings OpenAI’s software engineering agent into AWS development environments.
OpenAI says Codex is used by more than five million people every week. Through Amazon Bedrock, teams can use Codex to write, review, debug, and modernize code within AWS infrastructure, including Commercial and GovCloud regions.
The launch is positioned around enterprise production workflows rather than experimentation. OpenAI says customers can now bring frontier AI into AWS environments through existing security, compliance, procurement, billing, and governance processes.
The next phase will include future availability for Daybreak, OpenAI’s cyber-focused work covering secure code review, threat modeling, patch validation, dependency risk analysis, detection, and remediation guidance.
OpenAI models arrive inside AWS workflows
OpenAI on AWS gives enterprises access to OpenAI models through an operating model already used by AWS customers. The arrangement is designed to reduce the operational work involved in moving from AI evaluation into deployed applications.
OpenAI models on Amazon Bedrock allow teams to build AI applications using AWS security and governance controls. Codex on Amazon Bedrock gives software teams access to OpenAI’s agentic coding capabilities in the environments where they already build and ship.
For enterprise AI teams, the announcement brings OpenAI models into procurement and governance channels that may already be approved internally. That could reduce the time spent on separate vendor processes, security reviews, and production readiness checks.
OpenAI says the AWS path is intended to help organizations “spend less time navigating operational barriers and more time building.”
Amgen and Autodesk assess OpenAI on AWS
The announcement includes early enterprise customer views from Amgen and Autodesk, both focused on how OpenAI models and Codex could fit into existing AI and development workflows.
Sean Bruich, Senior Vice President, Chief Technology Officer at Amgen, says: “At Amgen, we’re focused on applying advanced AI in ways that may help accelerate the delivery of potential new therapies while equipping our teams with advanced tools. OpenAI’s GPT-5.5 and frontier models offer compelling advances in capability, quality, and consistency that matter in a field where the questions are complex and the standards for scientific accuracy and decision quality are exceptionally high. Making these models available on AWS gives us an important new path to explore and scale those capabilities within the responsible AI framework, including security, governance, and operational frameworks across the enterprise.”
Autodesk is evaluating OpenAI models and Codex on Amazon Bedrock for development workflows and decision support across design and engineering use cases.
Ritesh Bansal, VP of Analytics Data, Agentic AI and AI/ML Platform at Autodesk, says: “Autodesk is the technology platform for the people who design and make the world around us. Workflows like building design are highly iterative, requiring precision, coordination, and continuous refinement across teams. With OpenAI models and Codex now generally available on Amazon Bedrock, our teams are evaluating how frontier AI capabilities and AI-powered development tools on scalable, secure AWS infrastructure can help accelerate development workflows and support more informed decision-making for our customers.”
Daybreak cyber capabilities set for future availability
OpenAI says it will continue expanding the capabilities available through AWS, including future availability for Daybreak.
Daybreak includes cyber models and Codex Security. OpenAI describes it as work designed to help cyber defenders see risk 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 everyday development.
The cyber capabilities have not yet been made available through AWS in this announcement. OpenAI says AWS can provide a route for security teams to adopt specialized capabilities such as Daybreak through the security, governance, procurement, and operational frameworks they already use.
The general availability of OpenAI frontier models and Codex on AWS gives enterprise customers a new route to use OpenAI models through Amazon Bedrock. OpenAI says it will continue expanding the capabilities available through AWS as more organizations move from AI evaluation to production deployment.
