GPT-5.5, GPT-5.4, and Codex go GA on Amazon Bedrock at OpenAI's own per-token rates
OpenAI's three models are now GA on Amazon Bedrock, priced identically to the direct OpenAI API with no markup — the first concrete delivery from April's restructured Microsoft-OpenAI exclusivity agreement. AWS developers can call them via the Responses API under existing IAM, VPC, and KMS controls; Codex also runs through the CLI and IDE integrations — VS Code, JetBrains, and Xcode — with prompts not shared with OpenAI.
