AWS and OpenAI are expanding their partnership to bring frontier intelligence to the infrastructure millions of organizations already trust. Enterprises want the most capable AI models and agents, with the security, operational maturity, and data governance that production workloads demand. Today, we’re bringing those together with three new offerings on Amazon Bedrock, all in limited preview: the latest OpenAI models, Codex, and Managed Agents powered by OpenAI. First, the latest OpenAI models are available on Amazon Bedrock. For the first time, AWS customers can access OpenAI frontier models through the same Bedrock services they already use for model access, fine-tuning, and orchestration. OpenAI models on Bedrock inherit the enterprise controls customers depend on, including IAM, AWS PrivateLink, guardrails, encryption, and CloudTrail logging. Second, Codex on Amazon Bedrock brings the OpenAI coding agent into the AWS environments where enterprise teams already build. Customers authenticate with AWS credentials and run inference through Bedrock. Codex will be available through Bedrock via the Codex CLI, desktop app, and VS Code extension. Usage of both OpenAI models and Codex can be applied toward existing AWS cloud commitments. Lastly, Amazon Bedrock Managed Agents, powered by OpenAI, makes it fast to deploy production-ready OpenAI-powered agents on AWS. At the core are the latest OpenAI frontier models and the OpenAI agent harness, engineered for faster execution, sharper reasoning, and reliable steering of long-running tasks. Every agent has its own identity, logs each action, and runs in your environment with all inference on Amazon Bedrock. Managed Agents works with Amazon Bedrock AgentCore, which provides the default compute environment. Read the  blog  to learn more.
