Google Cloud and OpenAI announced on October 21, 2026 that OpenAI’s frontier models and Codex agentic workflows are coming to Google Cloud’s Model Garden. OpenAI models will be transacted through the Google Cloud Marketplace, so usage appears on a single Google Cloud invoice and draws down existing GCP commitments.
Google Cloud’s blog names three OpenAI models being added. GPT-6 Astra is positioned for coding, computer use, professional and scientific research. GPT-6.1 Sol is described as a lower-cost near-Astra option for agentic coding. GPT-6 Luna is a fast, cost-efficient model. Google Cloud says it is now the only hyperscale provider offering all three leading closed-source LLMs alongside 200-plus first-party, third-party and open models.
What is and is not available yet
Availability is described as starting “in the coming weeks”, and neither company has given a general-availability date or per-model pricing. OpenAI says its models will soon also be available in Google Antigravity and the Gemini Agent. Google states customer prompts, context and outputs remain within the customer’s data perimeter and are never used to train foundation models, with Zero Data Retention and Confidential Compute listed as coming soon.
That last point is the one to watch. Zero Data Retention and Confidential Compute are explicitly marked as not yet available, so an enterprise buyer cannot yet assume those protections apply from day one.
There is also a naming inconsistency worth noting. Reuters reported on September 28, 2026 that OpenAI shelved a model called GPT-6.1 Astra over internal safety concerns, while the Google Cloud blog lists GPT-6 Astra and GPT-6.1 Sol as separate offerings. We have reported the model names as Google published them and are not assuming they resolve to the earlier report.
Why a competitor partnership matters
The practical change is procurement. Running OpenAI models on a Google Cloud invoice removes a separate billing relationship and lets teams spend against existing GCP commitments. For anyone already committed to Google Cloud, that is a real simplification rather than a capability change.
The competitive angle is that the largest AI labs are increasingly selling through each other’s clouds. Our coverage of OpenAI’s $30 billion raise and Anthropic’s IPO covers where the money in the sector is moving.
What we did not do
We did not run the API, benchmark the models, or verify any performance or capability claims. All model descriptions, the data-perimeter statement and the availability timing come from Google Cloud’s and OpenAI’s own announcements.
