OpenAI: frontier models and Codex now available on AWS

OpenAI announced on 1 June 2026 that its frontier models and Codex are now available on AWS (Amazon Web Services). With this, OpenAI expands the channels through which users can access its most advanced models and coding tools, adding another major cloud platform.

What was announced?

According to the title of the announcement, OpenAI’s frontier models — the name for the most advanced models in the company’s portfolio — and Codex are becoming available within AWS. Codex is OpenAI’s model and coding agent that helps developers write, modify and explain code. Availability through AWS means users of that cloud can access them within an environment they already use.

What remains unknown?

From the available summary of the announcement, it is not possible to reliably determine which models exactly are covered, in which AWS regions they are available, and under what pricing model they are offered. We deliberately do not state those details here so as not to relay unconfirmed data. For the exact list of models and commercial terms, the official announcements from OpenAI and AWS need to be followed.

Why does it matter where models are available?

The availability of frontier models on multiple cloud platforms reduces users’ dependence on a single provider and makes it easier to integrate AI into existing systems. For enterprises already operating on AWS, the ability to use OpenAI’s models and Codex within the same environment can simplify development and cost management.

What’s next

Since such distribution announcements are often supplemented by technical documentation and price lists, it is worth following the subsequent publications of both sides. Only the full documentation will show how broad the integration of OpenAI’s models and Codex on AWS will be in practice.
