OpenAI GPT-5.5, GPT-5.4, and Codex Now Generally Available on Amazon Bedrock
OpenAI
OpenAI's GPT-5.5, GPT-5.4, and Codex coding agent became generally available on Amazon Bedrock on June 1, 2026. Pricing matches OpenAI's direct rates with no additional fees; usage counts toward AWS commitments. Enterprises gain AWS-native security controls (IAM, VPC, KMS, CloudTrail) and Bedrock's inference durability, with Codex supporting VS Code, JetBrains, and Xcode integrations.
Why it matters
Removes the primary enterprise barrier to adopting Codex by integrating it into the AWS compliance and procurement ecosystem that large organizations already operate; early adopters include Amgen and Autodesk.
