On 21 October 2026, Google Cloud announced that three OpenAI models, GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna, are now available in its Model Garden. For now this is a private preview open to select enterprise customers, with more access promised soon. Customers can build through Google Cloud's APIs from day one, and developers can point their local Codex CLI and Desktop workflows at Google's Gemini platform for inference.
“Helping customers put AI to work across their enterprise content requires leading models backed by strong security and rigorous compliance standards”

Google describes the three as a ladder. Astra is meant for demanding coding, computer use and professional or scientific work. Sol offers close to Astra's intelligence at a lower price, and Luna handles fast, cheap everyday tasks at scale. With them, Google says it is the only hyperscaler offering all three leading closed-source language models, plus over 200 other models, and it already carried Gemini and Claude.
The commercial and security terms are a large part of the pitch. OpenAI usage is billed through Google Cloud Marketplace on a single invoice, draws down a customer's existing commitments and counts toward Flexible Savings Plans. Prompts and outputs stay inside the customer's data perimeter and are not used for training. The models run on dedicated Google infrastructure behind isolated gateways, with VPC Service Controls and unified audit logging. Zero Data Retention and Confidential Compute are listed as coming soon.

Google frames the move as a matter of choice: it argues that enterprise AI means matching each workload to the right model, without lock-in or separate vendor contracts. Box, one of the customers quoted, says it will offer OpenAI models alongside Google Cloud's security and compliance. RuntimeWire reads the deal more bluntly, as marketplaces turning into distribution channels that let Google keep enterprise spending even when a customer picks a rival's model.
What comes next is only partly pinned down. OpenAI models are due in Gemini for business and in Google Antigravity, both marked coming soon. RuntimeWire reports that general availability is planned within weeks, citing Google Cloud and OpenAI, although Google's own post gives no such timing.
