AWS is packaging its AI story as a full work stack instead of a loose collection of services. On April 28, it opened Amazon Quick to Free and Plus signups with no AWS account required, expanded Amazon Connect into four agentic business solutions, and said GPT-5.5, Codex, and OpenAI-powered Managed Agents are coming to Amazon Bedrock in limited preview.
The important shift here is distribution, not one more model endpoint. OpenAI says GPT-5.5, Codex, and Bedrock Managed Agents are entering limited preview on AWS, giving enterprises a way to keep identity, security, and procurement inside Amazon's stack.
