AWS Launches OpenAI Models on Bedrock After Exclusivity Ends
Just one day after Microsoft and OpenAI ended their cloud exclusivity arrangement, AWS announced that GPT-5.5 and GPT-5.4 are now available on Amazon Bedrock. The partnership includes Codex on Bedrock and a new Managed Agents offering built on the OpenAI harness. Customers can now use existing AWS credentials, security controls, and apply usage toward AWS cloud commitments.
The bottom line: Marketing data teams running workloads on AWS can now access frontier OpenAI models without separate API contracts or data governance concerns, simplifying multi-cloud AI strategy.
