OpenAI is bringing its AI models to Google Cloud, ending Microsoft's exclusive hosting arrangement for them.
OpenAI will distribute its GPT products through Google Cloud, placing its technology on all three major U.S. cloud platforms. The move completes a rapid shift that began when Microsoft lost its exclusive license to OpenAI's intellectual property. Within weeks, enterprise developers will be able to access GPT products inside Google's model garden and its Antigravity coding environment.
The ChatGPT maker announced the arrangement in a blog post. The deal departs from years of direct rivalry between the two companies. It also completes an expansion that began less than six months ago, when OpenAI said Microsoft no longer held the exclusive license to its intellectual property.
Amazon started hosting OpenAI models in April, one day after that exclusivity expired. Google now joins the lineup. Developers can deploy the technology through Azure, Amazon Web Services, or Google Cloud without switching providers.
Google Cloud revenue growth accelerated to about 82% in the second quarter, up from 63% in the first quarter. Demand for AI workloads and custom chips fueled the jump. Amazon's cloud grew 37% in the second quarter, and Microsoft's grew 42%. All three companies report quarterly results next week.
Most business spending on AI goes to OpenAI and Anthropic, according to data from corporate card issuer Ramp. Some IT departments have integrated Google's Gemini models into their systems, and Google released Gemini 4 Argon in September.
OpenAI was founded in 2015 as a counterweight to the concentration of AI research at companies like Google. Two years later, Google researchers published the Transformer paper that reshaped the field. OpenAI captured mainstream attention with ChatGPT. The company now courts investors at a $1.4 trillion valuation and is targeting an initial public offering.
The partnership marks a reversal from pure competition. OpenAI already used Google's cloud last year to run ChatGPT and its application programming interface, but that arrangement handled compute behind the scenes. The new deal puts OpenAI's products in Google's storefront, making them visible to customers who browse the model garden.
Developers who build on Google Cloud can now call OpenAI's API or deploy models through the same console they use for Gemini and other tools. This reduces friction for enterprises that standardize on Google infrastructure but want access to the technology underlying ChatGPT.
"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," OpenAI said in a blog post.
OpenAI's $1.4 trillion valuation and IPO target put pressure on the company to grow revenue beyond consumer subscriptions. Enterprise distribution through all three major clouds supports that goal.
