OpenAI will offer frontier models and Codex through Google Cloud

OpenAI said on October 21, 2026 that it is partnering with Google Cloud to bring OpenAI’s frontier models and Codex agentic workflows into Google Cloud’s Model Garden.

The announcement says customers will get native access to those models for agentic workflows, using Google Cloud’s data governance and infrastructure. OpenAI frames the control as a requirement for regulated industries: deploying the models means deciding who can reach sensitive data and how that data is used. The integration is described as pairing the models with Google Cloud’s access controls, centralized data governance, and high-performance infrastructure.

Customers will buy the frontier models in Model Garden, and the sale will run through the Google Cloud Marketplace. Enterprises that already have Google Cloud spend commitments will be able to draw those commitments down for the purchases, OpenAI said.

OpenAI also said its models will soon be available in Google Antigravity and the Gemini Agent, which it presents as a way for enterprise customers to choose a model per task. The post does not describe what those two products include beyond that.

General availability is planned in the coming weeks. The announcement does not give a calendar date. A separate preview page says a limited preview is open by invitation. It lists two pieces: frontier models through the Responses API on Google Cloud, for supported development and internal testing, and Codex through the API in the Codex app, the command-line interface, and supported development environments. The form asks customers to register interest. OpenAI’s wording is that the preview is invite-only and that registering is a request to be considered, not an approval.

Greg Brockman, OpenAI’s president and co-founder, said in the announcement that Google Cloud is a platform where developers and businesses already build agents and write software, and that the partnership is a step toward offering OpenAI’s most capable models and Codex there. Thomas Kurian, Google Cloud’s chief executive, said the company wants customers to have a broad selection of models, including OpenAI’s, so they can choose one for a given job with an eye on quality and cost.

The same post draws a boundary around the deal. Microsoft remains OpenAI’s primary cloud partner.

The same day, OpenAI published a separate note on partner safeguards and updated usage policies. That note is about how safety rules travel when other companies host or resell the models. It does not list Model Garden prices or which model names will be sold there. The Google Cloud posts do not list those prices or model names either.
