OpenAI models on Google Cloud and Antigravity

OpenAI and Google Cloud announced a partnership to bring OpenAI's frontier models and Codex agentic workflows to Google Cloud's Model Garden, available through Google Cloud Marketplace. The full GPT 6 and 6.1 suite, including Astra, Sol, and Luna, will launch on Google Cloud, with GPT models also integrated into Antigravity, Google's agent-powered coding tool. Google's infrastructure will support dynamic workload routing between LLMs based on performance, latency, and efficiency. Google states it will become the only large cloud provider offering access to all three leading closed LLMs; Model Garden already hosts more than 200 models including Gemini, Mistral, Llama, Gemma, and Anthropic's Claude. OpenAI noted that Microsoft continues to be its primary cloud partner.

The deal became possible after Microsoft's license to OpenAI's technology turned non-exclusive on April 27, 2026, ending its revenue share on Azure resales. AWS was first to capitalize on the opening, adding Codex to Amazon Bedrock by June 2026, while Microsoft retains priority access to new OpenAI products. Google had asked the FTC in December 2024 to break up the Microsoft exclusivity arrangement, and also supplies OpenAI with computing capacity under a 2025 deal. For enterprise customers, purchases of OpenAI models can be counted against pre-committed Google Cloud spending, and regulated customers can run the models within Google Cloud's existing access controls for agentic workflows.
