Almost as soon as OpenAI announced that its major investor and cloud partner, Microsoft, no longer has exclusive rights to any of its products, Amazon started gloating.

After the revised OpenAI/Microsoft agreement was announced on Monday, Amazon CEO Andy Jassy noted in a tweet that it was a “very interesting announcement.” That agreement solved OpenAI’s problem of allowing AWS to offer its products, an issue that crystalized after it signed an up-to-$50-billion deal with Amazon.

Amazon announced on Tuesday that AWS’s Bedrock service now has OpenAI’s latest models, its code-writing service Codex, and a new product for creating OpenAI-powered AI agents. Bedrock is Amazon’s AI app building and model-choosing service.

Amazon is calling the new agent service Bedrock Managed Agents. It is specifically designed to use OpenAI’s reasoning models, offering features like agent steering and security.

Amazon promises in its blog post that “this is the beginning of a deeper collaboration between AWS and OpenAI.” And it will certainly be interesting to watch.

The Microsoft/OpenAI relationship has reportedly been deteriorating for some time, with each of them finding comfort in the arms of their partner’s biggest rival. OpenAI has turned to AWS and Oracle. Microsoft to Anthropic; the Redmond-based software giant is also working on a new agent offering powered by Claude.
