OpenAI models, Codex, and Managed Agents come to AWS

OpenAI and AWS have expanded their partnership to make OpenAI's models, including GPT-5.5, available through Amazon Bedrock (AWS's managed service for using AI models). This integration lets enterprises use OpenAI's capabilities within their existing AWS security systems, workflows, and infrastructure, with three new offerings: OpenAI models on AWS, Codex (a coding assistant used by over 4 million people weekly) on AWS, and Amazon Bedrock Managed Agents for building AI agents that can execute multi-step workflows.
