AWS Bedrock adds OpenAI models, Codex, and managed agents service following revised Microsoft agreement
AWS has added OpenAI's latest models, Codex, and a new managed agents service to its Bedrock platform, one day after OpenAI revised its agreement with Microsoft. The integration follows OpenAI's up-to-$50 billion deal with Amazon.
AWS Bedrock adds OpenAI models, Codex, and managed agents service following revised Microsoft agreement
AWS's Bedrock service now includes OpenAI's latest models, its Codex code-writing service, and a new product called Bedrock Managed Agents, Amazon announced Tuesday. The integration came one day after OpenAI and Microsoft revised their agreement to end Microsoft's exclusive rights to OpenAI products.
Bedrock is Amazon's AI application building and model-choosing service. The new offerings became available following OpenAI's up-to-$50 billion deal with Amazon, which had been blocked by Microsoft's previous exclusivity arrangement.
What's included
The AWS integration includes:
- OpenAI's latest models (specific versions not disclosed)
- Codex code-writing service
- Bedrock Managed Agents, designed specifically for OpenAI's reasoning models
Bedrock Managed Agents offers features including agent steering and security controls, according to Amazon's blog post.
Shifting cloud partnerships
The announcement marks a significant shift in AI cloud partnerships. Amazon CEO Andy Jassy called the revised Microsoft-OpenAI agreement "a very interesting announcement" in a tweet Monday.
According to TechCrunch, the Microsoft-OpenAI relationship has been deteriorating, with both companies finding alternative partnerships. OpenAI has turned to AWS and Oracle, while Microsoft has partnered with Anthropic and is developing a new agent offering powered by Claude.
Pricing for OpenAI models on AWS Bedrock was not disclosed in the announcement.
What this means
This integration gives AWS customers direct access to OpenAI's models through Bedrock's unified interface, eliminating the need to work through Azure. It represents Amazon's aggressive push into the AI infrastructure market and validates its $50 billion investment in OpenAI. The speed of the integration—just one day after the Microsoft agreement revision—suggests Amazon had been preparing for this moment. The managed agents service specifically targeting reasoning models indicates AWS is positioning itself for the emerging agentic AI market, directly competing with Microsoft's Claude-based agent offerings.
