OpenAI and Google Cloud announced on October 21, 2026 that OpenAI's models are coming to Google Cloud's Model Garden, starting with a private preview for select enterprise customers. Google says GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna are rolling out in that preview, while OpenAI says "General availability is planned in the coming weeks."

#What changed?

OpenAI and Google Cloud "are partnering to bring OpenAI’s frontier models and Codex agentic workflows into Google Cloud’s Model Garden," OpenAI wrote. Google described the move as "launching OpenAI models in Google Cloud’s model garden."

#Which models are included?

Only Google's post names the models. Google describes them this way:

Model

Google's description

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."

Google says the three models "are rolling out now in private preview to select enterprise customers in Google Cloud’s model garden, with more coming soon." OpenAI's post does not name individual models and refers to its "frontier models."

#What about Codex?

Google says customers "can build with these models through our APIs and connect their local Codex CLI and Desktop workflows directly to our Gemini platform for inference." OpenAI's preview access form lists "Codex through the API in the Codex app, command-line interface (CLI), and supported development environments (IDEs)" as part of the preview.

#How does billing work?

"Google Cloud customers will be able to purchase OpenAI frontier models via model garden, transacted through the Google Cloud Marketplace," OpenAI says. "Enterprises with Google Cloud spend commitments will be able to draw down their GCP commitments for these purchases."

Google adds that usage "appears on a single Google Cloud invoice, draws down existing cloud commitments, and counts toward Flexible Savings Plans (FSP) across model providers."

#What does Google say about security?

Google says customer prompts, context and outputs "are never used to train foundation models," and that the models "run on dedicated Google Cloud infrastructure." It lists Zero Data Retention options and Confidential Compute as "coming soon," and says interactions run under an authenticated identity with VPC Service Controls protection and unified audit logging.

"We are focused on giving customers a broad selection of models, including those from OpenAI, so they can choose the right model for any given job, helping to deliver optimal quality and lower costs," said Thomas Kurian, Chief Executive Officer, Google Cloud, in OpenAI's post.

OpenAI's form says: "The preview is invite-only. Register your interest to be considered for early access." It describes the preview as letting "Select customers" evaluate OpenAI models "for supported development and internal testing use cases."

OpenAI says its models "will soon be available in Google Antigravity and the Gemini Agent." Google names the products as "Gemini for business and Google Antigravity."

#How does it compare?

"Microsoft remains OpenAI’s primary cloud partner," OpenAI says. Reuters reported that Google became the latest major cloud provider to offer OpenAI models "after OpenAI’s exclusive distribution arrangement with Microsoft expired in April," following Amazon Web Services. CNBC reported that OpenAI "will now have its models on the three major U.S. clouds."

Google claims it "is now the only hyperscale cloud provider offering access to all three leading closed source LLMs."

"This partnership is an important step in making our most capable models and Codex available where customers are already building, giving them even more choice in how they use frontier AI as we grow the agentic ecosystem together," said Greg Brockman, President and co-founder, OpenAI.

#What is still unclear?

  • General availability date. OpenAI says only "in the coming weeks."
  • Pricing. Neither company has published prices for OpenAI models on Google Cloud.
  • Regions. No source lists Google Cloud regions or data residency options.
  • Deal terms. No financial terms were disclosed.
  • More models. Google says "more coming soon" without naming them.
