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

New Features

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.

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.

What to do

• Configure Codex to run inference through Bedrock.
• Explore the Codex App, CLI, and IDE integrations.
• Read the launch blog for more information.
• Check the AWS Regions page for regional availability.
