OpenAI models and Codex on Amazon Bedrock are now generally available

OpenAI frontier models GPT-5.5 and GPT-5.4, and Codex, the OpenAI coding agent, are now generally available on Amazon Bedrock. AWS customers can access these latest OpenAI models through the same Amazon Bedrock APIs and controls they already use, and Codex is available for enterprise software development at scale. OpenAI models on Bedrock inherit full enterprise controls including IAM-based access management, encryption, and comprehensive logging, and customers can apply OpenAI usage toward their existing AWS cloud commitments.
