OpenAI and Google Cloud on October 21, 2026 announced a partnership that brings OpenAI’s frontier models and its Codex coding agent into Google Cloud’s Model Garden, the catalog of first-party, third-party, and open models that Google sells through its enterprise AI platform.
According to Google Cloud, three OpenAI models are rolling out now in private preview to select enterprise customers: GPT-6 Astra, aimed at demanding coding, computer-use, professional, and research work; GPT-6.1 Sol, which Google describes as near-Astra intelligence at lower cost; and GPT-6 Luna, a fast, cost-efficient model for everyday work at scale. Both companies say general availability is planned in the coming weeks. OpenAI’s preview sign-up page describes access as invite-only for now.
The commercial terms are the practical news for enterprise buyers. Customers will buy OpenAI models through Google Cloud Marketplace, usage will appear on a single Google Cloud invoice, and companies with Google Cloud spend commitments can draw those commitments down on OpenAI purchases. Google says the spend also counts toward its Flexible Savings Plans across model providers.
For developers, Google says customers can build with the models through its APIs starting today and connect local Codex CLI and Codex Desktop workflows to Google’s Gemini platform for inference. Both companies say OpenAI models will also come to Google Antigravity, Google’s agentic coding tool, and to Gemini for business and the Gemini Agent, though neither gave a date.
OpenAI frames the move around governance for regulated industries, pairing its models with Google Cloud’s access controls, centralized data governance, and infrastructure. Google Cloud says it is now the only hyperscale cloud provider offering access to all three leading closed-source LLMs, alongside more than 200 other models in Model Garden.
The partnership follows the end of Microsoft’s exclusive arrangement with OpenAI earlier this year. CNBC and Reuters report that Amazon Web Services began hosting OpenAI models in April after that exclusivity ended, which means OpenAI’s models will now be on all three of the largest U.S. cloud platforms. OpenAI’s own announcement notes that Microsoft remains its primary cloud partner.
Pricing for OpenAI models on Google Cloud was not disclosed in either company’s announcement.
