OpenAI will make its artificial intelligence models available to developers through Google Cloud in the coming weeks, ending years in which the two companies were better known as competitors.

OpenAI models are coming to Google Cloud. We're bringing our frontier models and Codex agentic workflows to Google Cloud's Model Garden, so enterprises can use our technology where they already build.

The models will arrive in Google Cloud's Model Garden and in the Antigravity coding tool in the coming weeks, and OpenAI's Codex agentic workflows will be part of the integration. With the deal, OpenAI's models will be available on all three of the top U.S. cloud infrastructure providers as the company works to grow beyond its consumer roots and reach more enterprise developers.

How the Deal Fits Into OpenAI's Cloud Expansion

Less than six months ago, OpenAI said Microsoft would no longer hold the exclusive license on its intellectual property. Microsoft's exclusivity ended in April, and the day after it did, Amazon announced plans to host OpenAI models. The Google deal extends that push, placing OpenAI's models inside platforms where enterprise developers already build rather than asking them to come to OpenAI first.

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. OpenAI said Google Cloud has long invested in machine learning and AI, calling it a destination for AI workloads and the developers building them.

Google Cloud customers will be able to buy OpenAI models through the Model Garden, with purchases processed via the Google Cloud Marketplace. Companies with Google Cloud spend commitments can apply those commitments to pay for the models. OpenAI models will also soon be available in Google Antigravity and the Gemini Agent.

OpenAI said the integration will pair its models with Google Cloud's access controls and data governance features, which are meant to help organizations in regulated industries control who can reach sensitive data.

Google Cloud's Strong Year

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 quarter, with demand for AI models and custom chips helping drive the increase. Amazon and Microsoft reported second-quarter cloud growth of 37% and 42%, respectively. All three companies report quarterly results next week, and those reports will land just as OpenAI's models begin appearing on Google Cloud.

Data from corporate card issuer Ramp shows most business spending on AI goes to OpenAI and Anthropic, though some corporate IT have also added Google's Gemini models to their systems. 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. The company is now courting investors at a $1.4 trillion valuation and is targeting an initial public offering.

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