Summary

OpenAI and AWS announced an exclusive partnership bringing GPT-5.5, GPT-5.4, Codex, and Bedrock Managed Agents (powered by OpenAI) to Amazon Bedrock in limited preview. Enterprise developers authenticate with AWS credentials and run inference through Bedrock. Managed Agents on Bedrock use the OpenAI agent harness for long-running tasks. Stratechery published an interview with Altman and AWS CEO Matt Garman. OpenAI committed exclusively to Amazon for this cloud distribution play.

Implications

• Breaks Microsoft cloud exclusivity — OpenAI now distributed through AWS, the enterprise cloud leader
• Codex on Bedrock means the OpenAI coding agent runs inside AWS security boundaries — directly competing with Claude Code on Bedrock (Anthropic’s existing relationship)
• “Exclusive with Amazon” is strategic: if you want OpenAI agents in the cloud, you need AWS
• Anthropic has been on Bedrock since 2023 — now shares the platform with its primary competitor
• Feeds: enterprise deployment thread, token economics thread, distribution thread
