What happened
OpenAI and Google Cloud said Wednesday that OpenAI's frontier models and its Codex coding agent are coming to Google Cloud's Model Garden, the catalog where business customers pick AI models. Google said GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna are rolling out now in private preview to select enterprise customers. OpenAI said general availability is planned "in the coming weeks."
Why it matters
The deal puts OpenAI's models on all three of the biggest U.S. cloud providers. Microsoft's exclusive license to OpenAI's technology ended in April, Amazon Web Services began hosting the models soon after, and now Google, OpenAI's main rival in AI and search, is selling them too. For businesses, it means fewer reasons to switch clouds just to use a particular model. Google said it is now the only hyperscale cloud offering "all three leading closed source LLMs," its phrase for OpenAI's, Anthropic's and its own Gemini models.
More context
How customers pay: Companies will buy the models through Google Cloud Marketplace, so the charges land on their Google Cloud bill. OpenAI said customers can count the purchases against spending they have already committed to Google. Google said developers can also connect Codex command-line and desktop tools to its platform starting today, and that OpenAI models are coming to its Gemini for business tools and its Antigravity coding app.
What each side said: Google Cloud CEO Thomas Kurian said the company wants to give customers "a broad selection of models, including those from OpenAI, so they can choose the right model for any given job." OpenAI President Greg Brockman called it "an important step in making our most capable models and Codex available where customers are already building." OpenAI's post ends: "Microsoft remains OpenAI's primary cloud partner."
The money backdrop: CNBC reported that Google's cloud revenue growth sped up to about 82% in the second quarter, versus 42% at Microsoft and 37% at Amazon. All three report quarterly results next week. Reuters noted cloud providers usually take a cut of model sales on their platforms, and that Anthropic's IPO filing shows 47% of its 2025 revenue came through Amazon's and Google's clouds.
How outlets framed it: Reuters led with OpenAI's "latest enterprise push" and a deepening tie "between two rivals." CNBC framed it as OpenAI expanding "beyond Microsoft." The Next Web stressed that OpenAI is now selling on "a rival's platform." The companies' own posts focused on customer choice and data controls for regulated industries such as banking and health care.
What's still unknown: Neither company disclosed prices, how revenue is split, or how many customers are in the preview. It's also not yet clear how the deal affects OpenAI's commercial terms with Microsoft, which has not publicly commented in the reports cited here. The cloud earnings reports next week may show how much AI model sales are adding to each company's results.
