OpenAI brings GPT-Astra and GPT-6 models to Google Cloud

Three OpenAI models enter private preview on Google Cloud's Model Garden, billed on the same invoice as the rest of your cloud spend.

OpenAI and Google Cloud announced on 21 October that OpenAI’s frontier models and Codex agentic workflows are coming to Google Cloud’s Model Garden. Three models started rolling out in private preview to select enterprise customers the same day: GPT-Astra for demanding coding, computer-use and research work, GPT-6.1 Sol for near-Astra performance at lower cost, and GPT-6 Luna for fast, cheap everyday tasks.

Usage is transacted through Google Cloud Marketplace, so it lands on the same invoice as the rest of a customer’s cloud spend and counts toward existing committed-spend agreements and Flexible Savings Plans. Google Cloud says this makes it the only hyperscaler offering all three major closed-source model families alongside its own Gemini models and the 200-plus others already in Model Garden. Support for Google Antigravity and Gemini for Business is planned but not yet live. No date has been set for general availability beyond the current private preview.

Why it matters: teams already locked into Google Cloud spend commitments can now reach GPT-Astra, Sol and Luna without opening a separate OpenAI billing relationship, which changes the calculus on staying multi-cloud versus consolidating model spend with one provider.

The caveat: this is private preview for select enterprise customers only, with no published general availability date, so most developers can’t try it yet.
