OpenAI will make its most advanced AI models and its Codex coding agent available through Google Cloud "in the coming weeks," the companies said on Wednesday, 21 October 2026, according to Reuters and Axios. The deal puts OpenAI's technology inside the cloud of the company behind Gemini, one of its fiercest rivals.
What's in the deal
- OpenAI's frontier models, including GPT-6 Astra, will be offered in Google Cloud's Model Garden, Reuters reported.
- Customers can buy through Google Cloud Marketplace and count the spending against their existing Google Cloud commitments.
- OpenAI models are also coming to Google's Antigravity development environment and Gemini Agent, according to Axios.
- Businesses in regulated industries can use Google Cloud's access controls and data-governance tools when building AI agents.
From Microsoft exclusive to every cloud
OpenAI's exclusive distribution arrangement with Microsoft expired in April 2026. Since then it has expanded to Amazon Web Services and now Google Cloud, so its models are available on all three of the biggest US cloud platforms. Google already supplies OpenAI with computing capacity under a deal signed last year.
Google Cloud chief executive Thomas Kurian has said previously that the cloud "welcomes any model popular with developers," Reuters noted.
Why it matters
For businesses, it means fewer barriers to mixing models from different AI companies on one platform. For Google, it is a trade-off: it earns a cut from selling OpenAI's models, but its own Gemini now faces a rival on its home turf. "Gemini now has to win those customers with OpenAI sitting right next to it," said analyst Mike Leone of Moor Insights, quoted by Axios.
Cloud platforms have become crucial sales channels for AI developers. Reuters noted that Anthropic's IPO filing shows 47% of its 2025 revenue came through the Amazon and Google clouds. Neither OpenAI nor Google has said how much extra business the new deal could bring.
What happens next
General availability is expected in the coming weeks. It is the latest sign that the AI industry's biggest players are increasingly both partners and competitors at the same time.
