Today, OpenAI and AWS are expanding our strategic partnership to help enterprises build using OpenAI capabilities in their AWS environments. We’re excited to give AWS customers access to the best frontier models, agents, and tools, which will operate within the systems, security protocols, compliance requirements, and workflows they already use.

The expanded partnership with Amazon brings together three key areas of work, all launching today in limited preview:

Together, these capabilities give organizations more ways to use OpenAI across application development, software engineering, and agentic workflows—while building within the infrastructure, security, governance, and procurement workflows they already use on AWS.

For many companies, using AI at scale requires bringing the best models to the systems their teams already use. That’s why we’re launching OpenAI models, including our best frontier model GPT‑5.5, on Amazon Bedrock.

Customers can now build with OpenAI models in AWS, alongside the services, security controls, identity systems, and procurement processes they already rely on.

For developers, that means more flexibility in how they build with OpenAI, from new AI applications to intelligence embedded in existing products to agentic workflows that can reason, take action, and support more complex business processes.

For enterprises, it means a clear single path from experimentation to production, with OpenAI capabilities available in the AWS environments where their most important workloads already run.

More than 4 million people now use Codex every week, and teams are using it across the software development lifecycle—to write code, explain systems, refactor applications, generate tests, modernize legacy codebases, and accelerate a broader set of professional workflows that extend beyond coding.
