OpenAI brings its AI models to Google Cloud, moving beyond Microsoft

OpenAI, the maker of ChatGPT, said on Wednesday, October 21, 2026 that its leading AI models and its Codex coding tools will be made available to businesses through Google Cloud, a direct rival of its long-time partner Microsoft. Customers will be able to use the models through Google Cloud's Model Garden and Marketplace. With the deal, OpenAI's models are now offered on all three major US cloud platforms, after Amazon began hosting them less than six months ago when Microsoft's exclusive arrangement ended. OpenAI said Microsoft remains its primary cloud partner.

Most large companies do not use AI models by downloading them. They rent them through a cloud provider, the company whose data centres run the computing. Each big cloud wants to offer the most popular models so customers keep their data, applications and spending with it. For years OpenAI's models were available to businesses mainly through Microsoft's Azure cloud, part of a close partnership between the two companies. That gave Microsoft an edge in selling AI to companies.

Being on Google Cloud changes the picture for businesses that already run their systems there. They can now use OpenAI's models without moving data to another cloud or signing a separate contract, alongside Google's own Gemini models and others. For OpenAI, more clouds mean more customers and more revenue. The arrangement is notable because Google is also one of OpenAI's main competitors in AI models, which shows how cloud providers now act as marketplaces for rival products.

Codex, which is included, is OpenAI's AI system for writing and fixing software code. Making it available through more clouds is likely to speed its use in companies, including Indian IT services firms and global capability centres that build software for clients on different cloud platforms. Large Indian firms that have standardised on Google Cloud gain another option for AI tools.

Short-term: Google Cloud customers can start testing OpenAI models and Codex in preview or within weeks. Microsoft loses part of its edge as the main route to OpenAI's technology for businesses.

Long-term: AI models are becoming products that are available almost everywhere, so cloud providers will compete more on price, data security and the tools around the models. For businesses, wider choice and competition could bring down costs and reduce dependence on a single provider.

Who is affected: Businesses and developers using Google Cloud, Microsoft and Amazon as cloud providers, OpenAI and its investors, rival AI model makers, and Indian IT firms that build AI applications for clients on different clouds.
