OpenAI Launches General Availability of Frontier Models and Codex on AWS

There are two primary delivery methods: OpenAI models available on Amazon Bedrock, and the provision of Codex also via Bedrock. The former enables the construction of AI applications under AWS-native security and governance controls.
Codex, the latter, is a software engineering agent used by over 5 million people per week. It assists with code creation, review, debugging, and modernization within the AWS environment. Both are available in Commercial and GovCloud regions.
Enterprises can deploy OpenAI into production through their existing procurement, security review, billing, and governance workflows. The goal is to reduce operational barriers and accelerate the transition from evaluation to actual deployment.
Going forward, OpenAI's "Daybreak" vision is also planned for release on AWS. This will include cyber models and Codex Security, aiming to enhance software resilience through secure code reviews and threat modeling.
