On 21 October 2026, Google Cloud announced that it is launching OpenAI models in its Model Garden, the catalogue of first-party, third-party and open models on its enterprise AI platform. The announcement came in a blog post by Michael Gerstenhaber, a vice president of product management for Gemini at Google Cloud. OpenAI has also published its own post, which CNBC quotes.

Announced and shipped are not the same here. Google says the models are rolling out in private preview to select enterprise customers, with more coming soon.

What Google Cloud announced

Google Cloud's post names three models and describes each in its own words:

  • GPT-6 Astra: "Designed for demanding work across coding, computer use, professional tasks, and scientific research."
  • GPT-6.1 Sol: "Near-Astra intelligence at lower cost across agentic coding, computer use, and professional work."
  • GPT-6 Luna: "A fast, cost-efficient model for everyday work at scale."

Those are Google's descriptions of the models, not independent evaluations.

Google also makes a market claim. It says it is now "the only hyperscale cloud provider offering access to all three leading closed source LLMs", alongside more than 200 first-party, third-party and open models on one enterprise AI platform. The Tech Outlook, reporting on 22 October, reproduced a Google Cloud post on X from 21 October that made the same claim. Both are Google's own statements.

What is available, and what is "coming soon"

Google's post says GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna are "rolling out now in private preview to select enterprise customers" in the Model Garden. Customers who want access are pointed to a form to express interest.

Google says that starting on 21 October, customers can build with the models through its APIs and connect their local Codex CLI and Desktop workflows to its Gemini platform for inference. It says OpenAI models will also come to Gemini for business and Google Antigravity, without giving a date beyond "coming soon". CNBC reported that Google is bringing OpenAI's GPT products to the Model Garden and the Antigravity coding tool "in the coming weeks".

Buying and security terms

Much of Google's pitch concerns how the models are bought and governed rather than how they perform. Google says that because OpenAI models are transacted directly through Google Cloud Marketplace, all usage appears on a single Google Cloud invoice, draws down existing cloud commitments and counts toward Flexible Savings Plans across model providers.

On security, Google says:

  • Customer prompts, context and outputs stay within the customer's designated data perimeter and are never used to train foundation models.
  • OpenAI models run on dedicated Google Cloud infrastructure, with queries routed through hardened, isolated gateways.
  • Every agent and model interaction runs under an authenticated identity, with VPC Service Controls protection and unified audit logging.

Two further features in Google's list are not yet available: Google describes Zero Data Retention options and Confidential Compute as "coming soon".

The post carries one customer quotation, from Yashodha Bhavnani, VP of AI Products at Box. She said that "By using OpenAI models through Google Cloud, we will be able to give customers access to OpenAI’s frontier AI models alongside Google Cloud’s security and compliance capabilities". The wording is future tense.

The wider picture, according to CNBC

CNBC reported that the move puts OpenAI's models on all three of the top US cloud infrastructure providers. It described the effort as reflecting "a growing push to expand distribution" of OpenAI's technology to enterprise developers. CNBC also reported that the day after Microsoft's exclusivity ended, Amazon unveiled plans to host OpenAI models, and that it started hosting them in April.

CNBC quotes OpenAI's blog post as saying: "Google Cloud's longstanding investment in machine learning and AI has made it a destination for AI workloads and the developers and data scientists building them." CNBC adds that Google and OpenAI partnered the previous year, when OpenAI said it was using Google's cloud to run ChatGPT and its application programming interface.

CNBC supplies the competitive context:

  • Google's cloud annualised revenue growth accelerated to about 82% in the second quarter from 63% in the first, partly on demand for AI models and custom chips. Amazon and Microsoft posted second-quarter cloud growth of 37% and 42%. As of CNBC's 21 October report, all three were due to report quarterly results the following week.
  • According to data from the corporate card issuer Ramp, cited by CNBC, most business spending on AI goes to OpenAI and Anthropic, though some corporate IT departments have integrated Google's Gemini models. CNBC notes that Google announced its next-generation Gemini 4 Argon model in September.
  • CNBC reports that OpenAI is courting investors at a $1.4 trillion valuation and targeting an initial public offering.

What to watch

My reading is that this is a distribution deal more than a model launch. The announced advantages are one invoice, spending that counts against existing commitments and enterprise data controls, and two of the controls are still listed as coming soon.
