OpenAI models on Amazon Bedrock

OpenAI and Amazon Web Services said on June 1 that GPT-5.5, GPT-5.4 and Codex are now generally available through Amazon Bedrock, adding OpenAI’s flagship models to AWS’s managed model marketplace. AWS said customers can call the models through Bedrock’s next-generation inference engine and use Bedrock’s built-in security, governance and cost controls. OpenAI said the launch lets customers use its models inside AWS systems, identity controls and procurement processes they already use. ### What is actually being offered through Bedrock? AWS said the Bedrock launch covers GPT-5.5, GPT-5.4 and Codex, OpenAI’s coding agent. In a June 1 AWS post, the company said the models are generally available on Bedrock for production use, while a separate AWS “What’s New” post described GPT-5.5 as OpenAI’s most capable model and said Codex can run through the Codex App, CLI and IDE integrations using Bedrock. (aws.amazon.com) OpenAI said the AWS offering comes in two forms: OpenAI models on Amazon Bedrock for AI application development, and Codex on Amazon Bedrock for software engineering work. OpenAI said Codex is used by more than 5 million people every week and can help teams write, review, debug and modernize code inside AWS environments. ### Why does the procurement detail matter to enterprise buyers? (aws.amazon.com) AWS said usage of OpenAI models and Codex on Bedrock can be applied toward existing AWS cloud commitments. OpenAI said customers can build with its models “alongside the services, security controls, identity systems, and procurement processes they already rely on,” a formulation aimed at companies that buy technology through centralized cloud contracts rather than separate software deals. (openai.com) AWS also said Bedrock uses pay-per-token pricing, with no seat licenses and no per-developer commitments. OpenAI’s developer documentation separately lists direct API prices for GPT-5.5 and GPT-5.4, while AWS said Bedrock pricing is aligned to OpenAI’s own pricing structure. ### How does this change how companies can deploy OpenAI models? (aws.amazon.com) Amazon said customers can use the OpenAI Responses API on Bedrock and call Bedrock endpoints through the OpenAI SDK. OpenAI’s developer guide includes examples for running `openai.gpt-5.5` in Bedrock regions and says customers need a Bedrock API key stored as an AWS bearer token. (aws.amazon.com) AWS said Bedrock keeps processing within the Bedrock region a customer selects for data residency needs. OpenAI said the models are available in AWS commercial and government regions, which is significant for customers that need region-specific deployment, procurement controls or public-sector compliance paths. ### Which buying centers inside a company does this touch? (aws.amazon.com) OpenAI said the point of the AWS launch is to bring its models to “the systems their teams already use.” In practice, that means the decision can move beyond an individual developer or innovation team and into cloud procurement, security review, identity management and compliance approval, because the models are being bought and governed inside AWS rather than through a separate vendor stack. (aws.amazon.com) That is an inference from the companies’ stated emphasis on procurement, governance and security controls. Bedrock’s own product page says the service is used by more than 100,000 organizations worldwide and presents OpenAI alongside other model providers under a single control plane. That setup gives enterprise technology teams a way to compare and operate multiple models inside existing AWS workflows rather than stand up separate commercial arrangements for each provider. That reading is based on AWS’s description of Bedrock’s unified platform. (openai.com) ### What should customers watch next? AWS documentation now lists OpenAI model cards, supported regions and Bedrock integration details, and OpenAI has published separate guides for using its models on Bedrock and configuring Codex for Amazon Bedrock. The next practical step for customers is checking which Bedrock region and model combination is supported for their account type, then deciding whether to route usage through existing AWS commitments or through OpenAI’s direct platform.
