The Google Cloud announcement page is dated October 22, 2026, one day after this October 21 review. It describes a private preview for selected enterprise customers and says models are rolling out "now." The supplied evidence does not establish whether access has begun at review time.
For enterprise buyers, the announcement describes a purchasing route that would count toward existing Google Cloud spending commitments. Its usefulness depends on preview eligibility, pricing and the availability of required data controls.
What the page describes
Google names GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna as the private-preview models. It says customers can build through its APIs and connect local Codex CLI and Desktop workflows to the Gemini platform for inference. No integration test is supplied for those connections.
The page lists OpenAI access through Google Antigravity and Gemini for business as "coming soon."
What buyers need to confirm
According to Google, OpenAI model usage purchased through Google Cloud Marketplace draws down existing cloud commitments. That could make this route relevant to organizations allocating an existing Google Cloud budget. The supplied announcement gives no token prices, so the billing arrangement alone does not establish a cost saving.
Google also says customer prompts, context and outputs are never used to train foundation models. The same page lists Zero Data Retention options and Confidential Compute as coming soon. Teams requiring either control should confirm its availability for their accounts before scheduling a migration.
Before evaluating this route, confirm preview eligibility and access timing with Google, then check pricing and required data controls.
