OpenAI's GPT-5.5 and Codex Now Available on Amazon Bedrock

OpenAI's GPT-5.5 and Codex models are now in general availability on AWS's Amazon Bedrock service, expanding OpenAI's footprint in cloud marketplaces and simplifying enterprise access to the models. The move allows AWS customers to invoke GPT-5.5 via Bedrock's unified API without separate OpenAI accounts or billing.

For enterprise architects evaluating multicloud and abstracted model access, this integration removes friction for teams standardized on AWS—though model costs and inference latency remain key variables in buy-vs-build decisions.
