On April 28, 2026, OpenAI announced that GPT models, Codex, and Managed Agents are now available on AWS. The announcement comes on the same day as the amended OpenAI × Microsoft partnership agreement, and marks the first OpenAI presence outside the Microsoft Azure (Azure OpenAI Service) ecosystem.
What Was Announced?
Three OpenAI products are coming to AWS:
- GPT models — OpenAI flagship models
- Codex — an agentic code platform
- Managed Agents — hosted agentic runtime services
The goal, in OpenAI’s words: “to enable enterprise customers to build secure AI systems within their AWS environments.”
What Does This Mean in Practice?
AWS enterprise customers previously could not use OpenAI models without leaving the AWS perimeter or combining with Azure. Now IAM policies, VPC isolation, governance controls, and data requirements remain within AWS. Customers who avoided Azure for organizational, multi-cloud, or compliance reasons gain access to OpenAI without compromise.
Details of the integration mechanism — whether via AWS Bedrock, as a standalone service, or as a Marketplace offering — were not elaborated in the announcement. The same applies to pricing, available regions, and mapping of specific SKUs to OpenAI Platform tiers. That information will emerge through AWS’s own documentation as the rollout progresses.
Frequently Asked Questions
- What does this mean for AWS enterprise users?
- AWS customers can build AI applications with OpenAI models and tools without leaving the AWS perimeter — data, IAM policies, VPC isolation, and cloud governance remain within AWS, without replication to a separate OpenAI Platform stack.
- Which OpenAI products are specifically being brought over?
- Three products: GPT models, Codex (an agentic code platform), and Managed Agents (hosted agentic runtime services). Details on the integration mechanism, regions, and pricing were not elaborated in the announcement.
