Executive Summary
Amazon Web Services (AWS) has announced the general availability of OpenAI's GPT-5.5 and GPT-5.4 models, along with the Codex coding agent, on its Amazon Bedrock platform. This integration provides developers and enterprise customers access to OpenAI's latest models for complex reasoning, coding, and agentic workflows via a secure, pay-per-token API. The service leverages Bedrock's high-performance inference engine, ensuring reliability and data residency within the customer's chosen AWS region.
Key Takeaways
* New Models: Customers can now access GPT-5.5 for the most demanding workloads and GPT-5.4 for a balance of price and performance.
* AI Coding Agent: OpenAI's Codex is available for AI-powered software development, including writing, refactoring, debugging, and testing code, and is powered by GPT-5.5 on Bedrock.
* Access & Integration: The models are accessible through the OpenAI Responses API via the OpenAI SDK, CLI tools, and IDE integrations for VS Code, JetBrains, and Xcode.
* Pricing: The service uses a pay-per-token model with no seat licenses or per-developer commitments.
* Infrastructure: It runs on a new Bedrock inference engine designed for high performance and reliability, which queues requests during high demand rather than rejecting them.
* Data & Security: All data processing remains within the customer-selected AWS Region to meet data residency requirements.
* Availability: GPT-5.5 is currently available in the US East (Ohio) region, while GPT-5.4 is available in US East (Ohio) and US West (Oregon).
