Summary

OpenAI's GPT-5.5, GPT-5.4, and Codex models are now generally available on Amazon Bedrock, enabling their deployment in production applications and agents. GPT-5.5, described as OpenAI's most advanced frontier model, excels at complex, multi-step tasks like code writing and debugging, data analysis, and document generation, with pricing matching OpenAI's direct rates. Codex, an AI-powered coding agent used by over 5 million people weekly, facilitates writing, refactoring, debugging, and testing code, with its inference now powered by GPT-5.5 for enhanced quality. Amazon Bedrock provides a high-performance, reliable, and secure inference engine, featuring isolated queues, automated capacity management, and durable request state capture. It also integrates AWS governance controls like IAM, VPC, KMS encryption, and CloudTrail audit logging, ensuring data privacy by not using prompts or responses for model training. Future plans include Amazon Bedrock Managed Agents and OpenAI's Daybreak cyber models.
