OpenAI’s GPT models and Codex agentic workflows will appear in Google Cloud’s Model Garden. They will also arrive in the Antigravity coding tool in the coming weeks.

The deal puts OpenAI’s models on all three of the top U.S. cloud providers. OpenAI is trying to reach more enterprise developers as it builds a business beyond its consumer products.

What Google Cloud Customers Will Get

Customers will be able to buy OpenAI models through the Model Garden. Purchases will be processed through the Google Cloud Marketplace.

Companies with Google Cloud spending commitments can use them to pay for the models. OpenAI models will also come to the Gemini Agent soon.

OpenAI said the setup will pair its models with Google Cloud’s access controls and data governance. The company said this matters for regulated industries that must control who can see sensitive data.

In a blog post, OpenAI said Google Cloud’s long investment in machine learning has made it a destination for AI workloads.

Google and OpenAI have worked together before. Last year, OpenAI said it was using Google’s cloud to run ChatGPT and its application programming interface.

How OpenAI Got Here

Less than six months ago, OpenAI said Microsoft would no longer hold an exclusive license on its intellectual property. The day after that ended, Amazon announced plans to host OpenAI models.

Google has had a strong year in cloud computing. Annualized revenue growth in the segment rose to about 82% in the second quarter, up from 63% in the first.

Demand for AI models and custom chips helped drive that growth. Amazon and Microsoft reported second-quarter cloud growth of 37% and 42%. All three companies will report quarterly results next week.

Data from corporate card issuer Ramp shows most business spending on AI goes to OpenAI and Anthropic. Some corporate IT departments have also added Google’s Gemini models.

In September, Google announced its next-generation Gemini 4 Argon model. OpenAI was founded in 2015 partly as a counterweight to the concentration of AI research at companies like Google.

OpenAI is now courting investors at a $1.4 trillion valuation. It is also targeting an initial public offering.

Shares of Alphabet were down 1.62% on Wednesday, the day the news was announced.
