OpenAI models, Codex, and Managed Agents come to AWS
Source: OpenAI Blog
Expanded partnership overview
Today, OpenAI and AWS are expanding our strategic partnership to help enterprises build using OpenAI capabilities in their AWS environments. AWS customers now have access to the best frontier models, agents, and tools, which 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:
- OpenAI models on AWS
- Codex on AWS
- Amazon Bedrock Managed Agents, powered by OpenAI
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.
OpenAI models 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 frontier model GPT‑5.5, on Amazon Bedrock.
- Build with OpenAI models in AWS alongside existing services, security controls, identity systems, and procurement processes.
- Developers gain flexibility to create new AI applications, embed intelligence in existing products, and design agentic workflows that can reason, take action, and support complex business processes.
- Enterprises benefit from a clear single path from experimentation to production, with OpenAI capabilities available in the AWS environments where their most important workloads already run.
Codex on AWS
More than 4 million people now use Codex every week. Teams leverage it across the software development lifecycle—to write code, explain systems, refactor applications, generate tests, modernize legacy codebases, and accelerate broader professional workflows that extend beyond coding. Codex is also used to accelerate research, analysis, and document‑based work by connecting with everyday apps and tools, from summarizing source materials to creating briefs, slide decks, and spreadsheets.
- Codex is OpenAI’s frontier coding harness and product suite.
- Organizations can now power Codex with OpenAI models served directly from Amazon Bedrock.
- Any company with an AWS commitment and Bedrock access can start using OpenAI’s powerful coding agent and products frictionlessly.
- All customer data is processed by Amazon Bedrock, and eligible customers can apply Codex usage toward their AWS cloud commitments.
Getting started with Codex
- Configure Codex to use Bedrock as the provider.
- Use the Bedrock API to integrate Codex, starting with:
- Codex CLI
- Codex desktop app
- Visual Studio Code extension
Codex on Bedrock is available in limited preview.
Amazon Bedrock Managed Agents
With Bedrock Managed Agents, organizations can build agents that:
- Maintain context
- Execute multi‑step workflows
- Use tools
- Take action across complex business processes
This service helps customers move from experimentation to production faster, while keeping agent development aligned with the infrastructure, security, and operational standards expected from AWS. Managed Agents handle deployment, tool use, orchestration, and governance, with built‑in integration across Amazon’s security and compliance controls.
Benefits for enterprises
- Security & compliance: Leverage AWS’s enterprise‑grade security, billing, and high‑availability features.
- Operational efficiency: Reduce the overhead of building and maintaining AI infrastructure.
- Scalable path to production: Accelerate the transition from prototype to production for both models and agents.
- Unified procurement: Apply usage toward existing AWS cloud commitments.
Our strategic partnership with Amazon focuses on helping organizations deploy advanced AI at production scale. With OpenAI models, Codex, and Managed Agents now on Amazon Bedrock, customers have a faster, more secure path to putting AI to work across their business. We’re excited to see what your organizations build.
