OpenAI and Amazon Web Services on Tuesday announced an expanded collaboration that integrates OpenAI’s models directly into AWS infrastructure. The deal introduces three offerings in limited preview - OpenAI models on AWS, Codex on AWS, and Amazon Bedrock Managed Agents powered by OpenAI - with GPT-5.5 available on Amazon Bedrock and Codex able to run using Bedrock as the provider.

Key Points

  • OpenAI and AWS announced an expanded partnership on Tuesday to integrate OpenAI models into AWS environments via three limited-preview offerings.
  • GPT-5.5 is available on Amazon Bedrock, enabling customers to build applications with that model inside their existing AWS infrastructure and security frameworks.
  • Codex can now be powered by models served from Amazon Bedrock, with usage eligible to count toward AWS cloud commitments and access via Codex CLI, desktop app, and VS Code extension.

OpenAI and Amazon Web Services said Tuesday they have broadened their strategic relationship to embed OpenAI’s artificial intelligence models into AWS environments. The update brings three new offerings to a limited-preview phase, enabling enterprises to run OpenAI capabilities within their existing AWS setups.

The three offerings launching in limited preview are:

  • OpenAI models on AWS
  • Codex on AWS
  • Amazon Bedrock Managed Agents powered by OpenAI

As part of the expansion, OpenAI’s frontier model GPT-5.5 is now hosted on Amazon Bedrock. That allows customers to develop applications using OpenAI’s GPT-5.5 while keeping those applications inside their current AWS infrastructure and under the same security and operational controls they already use.

Codex, OpenAI’s coding assistant used by more than 4 million people each week, can now be driven by OpenAI models served from Amazon Bedrock. Customers will be able to configure Codex so that Bedrock acts as the provider, and usage routed through Bedrock will be eligible to count toward existing AWS cloud commitments. The Codex integration will be accessible through multiple developer interfaces, including the Codex command-line interface, the Codex desktop application, and a Visual Studio Code extension.

Amazon Bedrock Managed Agents, now powered by OpenAI models, are designed to let enterprises deploy agents that retain context over interactions, carry out multi-step workflows, and operate across business processes inside AWS environments. The agents are introduced as part of the limited-preview lineup alongside the other two offerings.

The companies said the integration is intended to let organizations make use of OpenAI’s capabilities without upending their current AWS systems. Specifically, the arrangement is positioned to preserve existing security controls and to respect compliance arrangements that enterprises have established within AWS.

All three offerings are being rolled out in a limited preview stage. The announcement focuses on the technical integration points - model availability on Bedrock, Codex configuration options, and managed agents - and emphasizes continuity with customers’ existing AWS infrastructure and governance frameworks.


Sectors potentially impacted: cloud infrastructure, enterprise software, developer tools.

Risks

  • Availability is limited - all three offerings are launching in limited preview, which creates uncertainty about wider access and timing for general availability - this impacts enterprise adoption and cloud infrastructure demand.
  • Customers must configure Codex to use Bedrock as the provider and route usage appropriately to have it count toward AWS cloud commitments, which implies integration and configuration requirements for development teams - this affects developer tools and enterprise software deployments.
  • While the integration is designed to preserve existing AWS security controls and compliance requirements, organizations will still need to validate that the combined OpenAI-AWS setup meets their internal and regulatory obligations before production use - this is relevant for regulated industries and compliance-sensitive operations.
