The bottom line: OpenAI’s GPT-5.5, GPT-5.4, and Codex are now production-ready on Amazon Bedrock with AWS governance integration, automatic capacity management, and OpenAI-aligned pricing.
OpenAI models GPT-5.5, GPT-5.4, and the Codex agent are now available for production deployment via Amazon Bedrock. Pricing aligns with OpenAI’s direct rates, with AWS commitments credited against usage.
GPT-5.5, GPT-5.4, and Codex are available on Amazon Bedrock and run on Bedrock’s high-performance inference engine. GPT-5.5 is OpenAI’s most advanced model and handles complex, multi-step tasks. It excels particularly in agent-driven programming—writing and debugging code across large codebases, data analysis, document generation, and orchestrating multiple tools to completion.
For CTOs and infrastructure teams, isolation and governance are critical: Amazon Bedrock offers automated capacity management with dedicated, isolated request queues. In case of hardware failures or node restarts, requests continue seamlessly rather than being resubmitted. All AWS governance controls apply—IAM permissions, VPC and PrivateLink isolation, KMS encryption, and CloudTrail audit logging. Prompts and responses are not used for model training and are not shared with model providers.
Codex is OpenAI’s agent for AI-assisted software development and is used by over 5 million people weekly. The model maintains context across entire repositories, systematically debugs ambiguous errors, and executes code changes with awareness of system dependencies. With GPT-5.5 as the inference backend, Codex operates more efficiently and delivers higher quality than earlier versions. Usage flows through Bedrock, and consumption counts toward existing AWS commitments.
