TL;DR

  • **Strategic partnership expanded:** Three AWS limited previews launched today: OpenAI models, Codex, and Bedrock Managed Agents powered by OpenAI
  • **OpenAI models on Amazon Bedrock:** Includes **GPT-5.5**; builds within AWS services, security, identity, and procurement controls
  • **Codex on AWS via Bedrock:** Coding assistance for writing, refactoring, tests, modernization, explanations, and some document work
  • **Commitment-aware usage:** With AWS commit and Bedrock access, **Codex can use Bedrock provider**; eligible usage counts toward AWS commitments
  • **Limited preview surfaces:** **Bedrock API**, starting with **Codex CLI**, Codex desktop app, and **Visual Studio Code extension**
  • **Amazon Bedrock Managed Agents powered by OpenAI:** Context retention, multi-step workflows, tools, business actions; Bedrock handles deployment, orchestration, governance

OpenAI and AWS are expanding their strategic partnership, according to OpenAI’s announcement, with three offerings launching today in limited preview for AWS customers: OpenAI models on AWS, Codex on AWS, and Amazon Bedrock Managed Agents powered by OpenAI.

The company mentions that OpenAI models, including GPT-5.5, are now available on Amazon Bedrock. OpenAI claims this gives customers a way to build with its models inside AWS environments while staying within the services, security controls, identity systems, and procurement processes they already use.

OpenAI also states that Codex is coming to AWS through Amazon Bedrock. The company says more than 4 million people use Codex every week and that teams are using it to write code, explain systems, refactor applications, generate tests, modernize legacy codebases, and handle some document-based work. OpenAI adds that customers with AWS commit and Bedrock access can configure Codex to use Bedrock as the provider, with customer data processed by Amazon Bedrock and eligible usage able to count toward AWS cloud commitments. Codex on Bedrock is available in limited preview through the Bedrock API, starting with Codex CLI, the Codex desktop app, and the Visual Studio Code extension.

The third piece is Amazon Bedrock Managed Agents, powered by OpenAI. OpenAI says the feature is intended for enterprises that want to deploy agents inside AWS and that it supports agents that maintain context, execute multi-step workflows, use tools, and take action across business processes. The company also asserts that Bedrock Managed Agents handles deployment, tool use, orchestration, and governance, with integration across Amazon’s security and compliance controls.

Taken together, the launch appears aimed at making OpenAI’s models and tools easier to adopt inside AWS environments rather than forcing enterprises to build around separate systems. OpenAI suggests the update is meant to give organizations a “faster, more secure path” to deploying AI across application development, software engineering, and agent workflows.
