OpenAI Ends Seven-Year Azure Exclusivity: GPT-5.5, Codex, and Managed Agents Launch on Amazon Bedrock in Limited Preview
On April 28, OpenAI made GPT-5.5, GPT-5.4, Codex, and Bedrock Managed Agents available on AWS — ending nearly seven years of Microsoft Azure being the only hyperscaler hosting OpenAI's proprietary models. GPT-5.5 pricing: $5/$30 per 1M input/output tokens with 1M context; GPT-5.5-pro at $30/$180 for higher accuracy. Codex is accessible via CLI, desktop app, and VS Code extension with AWS credential auth. Backed by $50B Amazon investment and 2GW Trainium capacity commitment. For builders: multi-cloud OpenAI access means you can now use GPT-5.5 with existing AWS IAM, PrivateLink, and CloudTrail — no new security model required.
