Amazon Bedrock integration runs Codex models under AWS-managed authentication and billing

What this changes for operators

• An operator with AWS infrastructure can now run OpenAI models through Amazon Bedrock, moving authentication and billing under AWS IAM and cost allocation instead of an external OpenAI API path.
• This reframes where the trust and identity boundary sits — Codex model calls become AWS-native, which changes compliance and credential-management decisions for AWS-policy organizations.
• Verification path: provision Codex models via Bedrock, confirm IAM scoping and that no model traffic leaves the AWS-managed path before treating it as compliance-satisfying.
