OpenAI's GPT-6 models land in Google Model Garden
Astra, Sol and Luna are due in Google's model catalog within weeks, payable from committed cloud spend rather than a new AI budget.
In short
OpenAI is putting GPT-6 Astra and the cheaper GPT-6.1 Sol and GPT-6 Luna into Google Cloud's Model Garden, with general availability announced for a few weeks out.
At a glance
- GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna are headed for Google Cloud's Model Garden.
- On token pricing, Sol sits 5 times below Astra and Luna 100 times below.
- Model Garden lists more than 200 models from Google, partners and open-source projects, per SiliconANGLE.
- General availability is set for within a few weeks of October 21, 2026; no firm date was given.
- Existing long-term cloud spending commitments can be used to pay for model access, OpenAI says.
OpenAI is putting three models into Google Cloud's Model Garden: flagship GPT-6 Astra plus the smaller GPT-6.1 Sol and GPT-6 Luna. General availability is promised within a few weeks of the October 21, 2026 announcement.
The procurement line is the real news
Companies that have signed a long-term spending commitment with Google Cloud can apply that commitment to OpenAI model access, according to OpenAI. For a platform team, that collapses two purchases into one: no second vendor contract, no ring-fenced AI budget, one bill. The report does not say which discount tiers or minimums apply.
A rival's models inside Google's own catalog
Model Garden is the shelf Google Cloud customers pick models from, and SiliconANGLE puts it at more than 200 models from Google, its partners and the open-source ecosystem. Adding Astra, Sol and Luna places OpenAI next to Google's own Gemini line in that list.
Google Cloud chief executive Thomas Kurian frames it as selection: customers should be able to match the model to the job, which he argues improves both quality and cost. Read plainly, that is Google declining to make its catalog a Gemini-only shelf.
Astra, Sol, Luna: quality traded for token price
Sol and Luna are scaled-down builds that give up some output quality in exchange for much cheaper tokens. Per token, Sol runs 5 times below Astra and Luna 100 times below. No absolute per-token rates for Google Cloud have been published.
Two claims travel with Astra: a perfect score on ExploitBench, which measures whether a model can find and exploit security flaws, and a hand in several AI-produced math results. Both come from the vendor side rather than from independent testing.
What we could not verify
OpenAI's own announcement text also mentions Codex workflows and distribution via Google Cloud Marketplace. The openai.com page for this news returned HTTP 403 when we tried to read it, so neither point could be checked against the original.
Launch date, pricing and regions remain open. Confidential Compute with TEE memory encryption, the Antigravity coding tool and Gemini Agent are named as planned hookups, not shipped ones.
