OpenAI brings GPT-5.5, Codex, and Managed Agents to Amazon Bedrock
OpenAI
AWS and OpenAI expanded their partnership and launched three offerings on Amazon Bedrock in limited preview: OpenAI's frontier models (GPT-5.5 and GPT-5.4), the Codex agent with CLI/desktop/VS Code support, and Bedrock Managed Agents based on OpenAI. GA is promised within weeks; the models are integrated with IAM, PrivateLink, guardrails, and CloudTrail.
Why it matters
The release came a day after the end of OpenAI's exclusivity with Microsoft and effectively makes Bedrock a second full-fledged distribution channel for OpenAI's frontier models in the enterprise.
Importance: 4/5
Major partnership + 6 independent confirmations + structural shift in frontier-model distribution.
