OpenAI and Amazon Web Services (AWS) have announced a major expansion of their strategic partnership, effectively bringing OpenAI’s most powerful frontier models, its Codex development suite, and new Managed Agents directly into the AWS ecosystem. This integration, launching today in limited preview, allows enterprises to build, deploy, and scale AI-powered solutions within the security, governance, and compliance frameworks they already trust on AWS.

Key Pillars of the Expanded Partnership

1. OpenAI Models on Amazon Bedrock: Customers can now access OpenAI’s latest frontier model, GPT-5.5, directly through Amazon Bedrock. This provides a unified path for enterprises to integrate top-tier generative AI into their existing products, internal tools, and complex business workflows while leveraging AWS's robust identity, security, and procurement processes.

2. Codex on AWS: Codex—OpenAI's "frontier coding harness"—can now be powered by OpenAI models served via Amazon Bedrock.

   • Enterprise Integration: Organizations can configure Codex to use Bedrock as its provider, allowing them to apply their existing AWS cloud commitments (billing) toward their Codex usage.

   • Multi-Platform Access: The capability is currently accessible via the Codex CLI, the Codex desktop app, and the Visual Studio Code extension.

3. Amazon Bedrock Managed Agents, Powered by OpenAI: This launch gives enterprises a turnkey way to deploy advanced agents. Bedrock Managed Agents handle the heavy lifting of agentic deployment—including tool use, orchestration, and security governance—so teams can focus on defining business logic rather than building infrastructure.

Why This Matters for Enterprises

For large organizations, "AI at scale" often means overcoming the friction of moving prototypes to production. This partnership addresses this by:

• Frictionless Procurement: Leveraging existing AWS commitments and budgets makes it easier for internal teams to adopt OpenAI technology without navigating new vendor procurement cycles.

• Operational Security: By running these capabilities within Amazon Bedrock, organizations benefit from the established compliance standards, identity controls, and high availability of the AWS cloud.

• Agentic Scalability: Managed Agents provide a "faster path to production" for complex, multi-step workflows that require persistence, state maintenance, and secure tool access.

This move significantly simplifies the "stack" for building AI-powered software. By having OpenAI’s most capable models and its primary developer agent, Codex, natively integrated with AWS infrastructure, developers can build agents that operate with enterprise-grade reliability and security.
