OpenAI brings models to AWS

OpenAI and Amazon Web Services said on April 28 that OpenAI’s latest models, Codex and managed agents are coming to Amazon Bedrock in limited preview. (openai.com) (aws.amazon.com) The lineup includes GPT-5.5 on Bedrock, plus Codex tools through the Codex command-line interface, desktop app and Visual Studio Code extension. (openai.com) (aws.amazon.com) AWS said Bedrock customers will get OpenAI models with Identity and Access Management, AWS PrivateLink, guardrails, encryption and CloudTrail logging already built into the service. (aws.amazon.com) OpenAI said the pitch is simple: companies want frontier models inside the cloud systems, security rules and procurement channels they already use for production workloads. (openai.com) (reuters.com) The timing matters because OpenAI and Microsoft rewrote their partnership on April 27, loosening a contract that had given Azure exclusive rights to sell most OpenAI services. (reuters.com) (cnbc.com) That change let Amazon move within a day, turning Bedrock into a direct distribution channel for OpenAI models alongside Anthropic, Meta and other providers already on the platform. (aws.amazon.com) (reuters.com) Reuters reported that Amazon invested $50 billion in OpenAI, while OpenAI committed to spend $100 billion on AWS over eight years and to use two gigawatts of Trainium computing. (reuters.com) At an AWS event in San Francisco, Chief Executive Matt Garman said customers had asked for this because their production applications and data already run on AWS. (reuters.com) OpenAI said more than 4 million people now use Codex every week, and AWS said both OpenAI model usage and Codex usage can count against existing AWS cloud commitments. (openai.com) (aws.amazon.com) The immediate result is that OpenAI’s products no longer sit only inside Microsoft’s cloud stack; they now arrive packaged with Amazon’s controls, billing and enterprise sales motion.
