OpenAI's latest AI models are coming to Google Cloud and Antigravity

OpenAI and Google have reached an arrangement to bring OpenAI’s frontier models to Google Cloud services and to Antigravity, Google’s agent-powered coding tool. OpenAI’s latest models are expected to join Google Cloud’s Model Garden in the coming weeks, expanding a catalog of more than 200 model options. Model Garden already includes Google’s Gemini models, open models such as Mistral, Llama, and Gemma, and Anthropic’s Claude. Google says the addition makes it the only large cloud provider offering all three leading closed large language models. The full current GPT 6 and 6.1 lineup—Astra, Sol, and Luna—will launch on Google Cloud, although Microsoft remains OpenAI’s primary cloud partner. Astra will cost more to run than the other models. Google Cloud can dynamically shift workloads among language models according to performance, latency, and efficiency. OpenAI models will run entirely on Google infrastructure, and customers will buy access through the Google Cloud Marketplace. Businesses with existing Google Cloud spending commitments will be able to apply those arrangements when adopting GPT models, potentially replacing models they already use.
