OpenAI lands on AWS Bedrock

OpenAI and Amazon Web Services said on June 1 that OpenAI’s GPT-5.5, GPT-5.4 and Codex are now generally available on Amazon Bedrock, extending a partnership the companies first disclosed in limited preview in April. AWS said customers can run the models in production workloads through Bedrock using the same security, governance and operational controls they already use across AWS. OpenAI said the Bedrock rollout gives enterprises a way to use its models inside existing AWS billing, compliance and workflow setups. The release also adds another cloud route for companies that want OpenAI models without buying them directly from OpenAI. ### Which OpenAI products are actually live on Bedrock now? AWS said GPT-5.5, GPT-5.4 and Codex are now generally available on Amazon Bedrock. In an April 28 launch note, AWS had described the same offerings — OpenAI models, Codex and managed agents powered by OpenAI — as being in limited preview. OpenAI said customers can access the offering in two main ways. (aws.amazon.com) OpenAI models on Amazon Bedrock let teams build applications with AWS-native security and governance controls, while Codex on Amazon Bedrock brings OpenAI’s software engineering agent into AWS for writing, reviewing, debugging and modernizing code. ### How is AWS positioning the offer to enterprise buyers? (aws.amazon.com) AWS said the models run on Bedrock’s inference engine and come with Bedrock’s security, governance and operational controls. An AWS blog post said customers can call the models through the OpenAI Responses API on Bedrock and keep processing within the Bedrock region they select for data residency needs. (openai.com) Amazon said pricing matches OpenAI’s first-party rates and includes no additional fees. Amazon also said usage can count toward AWS commitments, a detail likely to matter for large customers already spending against committed cloud contracts. ### Where does Codex fit in? OpenAI said Codex on Amazon Bedrock brings its coding agent into AWS environments where teams already build and ship software. (aws.amazon.com) The company said Codex is used by more than 5 million people every week. OpenAI’s developer changelog said on June 1 that Codex can now use supported OpenAI models available through Amazon Bedrock. (aboutamazon.com) The changelog said developers can configure Amazon Bedrock as the model provider so Codex runs with AWS-managed authentication, account controls and billing. ### What does Bedrock add beyond raw model access? Amazon Bedrock said it powers generative AI for more than 100,000 organizations worldwide and packages model access with enterprise controls, orchestration and infrastructure services. (openai.com) AWS also markets Bedrock Managed Agents as a way to build production-ready OpenAI-powered agents on AWS infrastructure. OpenAI said the AWS arrangement is meant to let enterprises use its models, agents and tools within systems, security protocols, compliance requirements and workflows they already use. (developers.openai.com) That language places the Bedrock offer less as a standalone model sale and more as an enterprise deployment option inside AWS’s existing control plane. That characterization is an inference from the companies’ product descriptions. (aws.amazon.com) ### What is Daybreak, and is it part of this launch? OpenAI has a separate Daybreak page that describes the product as a cybersecurity offering using GPT-5.5 and Codex Security to identify threats, generate patches and verify remediation across code and systems. The Bedrock general-availability announcements do not list Daybreak as one of the products now live on Bedrock. An AWS-linked news summary said Daybreak cybersecurity models are planned for future availability, but AWS’s own June 1 product pages focus on GPT-5.5, GPT-5.4, Codex and managed agents. (openai.com) ### What happens next for customers? June 1 product pages from AWS direct customers to Bedrock setup materials and API documentation for GPT-5.5, GPT-5.4 and Codex. (openai.com) OpenAI also maintains a signup page for access to OpenAI on AWS, and AWS continues to list Bedrock Managed Agents powered by OpenAI as part of the broader rollout.
