IT Home reported on October 21 that OpenAI and Google Cloud announced on October 21 local time that OpenAI’s frontier models and Codex coding agent will become available on the Model Garden and Marketplace platforms in the coming weeks. The partnership brings OpenAI’s models to all 3 major U.S. cloud providers.
This means that, in addition to Anthropic’s latest closed-source Claude models, OpenAI’s latest closed-source GPT models will also be available to users through Google Antigravity and Gemini Agent, without the risk of having their accounts banned by Anthropic. Gemini Agent is a general-purpose work agent spanning Workspace, Microsoft 365, and Slack, designed to route dynamically to the most suitable model for different tasks.
After OpenAI’s exclusive agreement with Microsoft expired in April 2026, Amazon announced the following day that it would host OpenAI models through AWS Bedrock; Google Cloud has now become the third provider.
IT Home previously reported that Gemini Agent was unveiled at “Gemini at Work 2026” on October 8. At the time, it could route between Gemini and Anthropic Claude models, while Google explicitly listed OpenAI and open-weight models as “coming later.”
Google Cloud CEO Thomas Kurian previously told Reuters that Google Cloud is an open platform that welcomes any model popular with developers.
