GPT-5.5, GPT-5.4, and Codex from OpenAI are now generally available on Amazon Bedrock

You can now use GPT-5.5 and GPT-5.4 in production workloads on Amazon Bedrock and build with Codex for AI-powered software development, with the same security, governance, and operational controls you already use across AWS. GPT-5.5 is the most capable model from OpenAI, excelling at agentic coding, data analysis, and multi-step autonomous tasks. It runs on the Bedrock next-generation inference engine, built for high performance, reliability, and security. Codex is available through the Codex App, the Codex CLI, and IDE integrations with Visual Studio Code, JetBrains, and Xcode. You can now configure Codex to run inference through Bedrock. Pricing matches OpenAI first-party rates, and usage counts toward existing AWS commitments. For Regional availability of GPT-5.5 and GPT-5.4 see the [AWS Regions page](https://docs.aws.amazon.com/bedrock/latest/userguide/models-region-compatibility.html).
