OpenAI's GPT models are coming to Google Cloud and Google's Antigravity coding tool
According to Ars Technica, OpenAI's GPT 6 and 6.1 models will run on Google's infrastructure. They are rolling out first in a private preview for select enterprise customers.
OpenAI and Google have reached an arrangement that will bring OpenAI's frontier models to Google Cloud services, according to Ars Technica. This story rests on that single report.
Ars Technica reported that the full suite of current GPT 6 and 6.1 models, named Astra, Sol and Luna, will launch on Google Cloud. GPT models will also appear in Antigravity, Google's agent-powered coding tool.
Google says all three OpenAI models are rolling out now in a private preview for select enterprise customers. Other interested customers can submit a request for early access. According to the report, that access works through the API, even for people using Codex CLI or Codex Desktop, with the inference running on Google's systems.
OpenAI's latest model will also appear in Google's "Model Garden" in the coming weeks, Ars Technica reported. The Model Garden already lists more than 200 options, including Google's Gemini models, open models such as Mistral, Llama and Gemma, and Anthropic's Claude.
The deal matters because it widens the choice of AI models on a major cloud platform. Google says it is now the only large cloud provider offering access to all three leading closed large language models.
According to Ars Technica, the OpenAI models will run entirely on Google's infrastructure, and transactions will go through the Google Cloud Marketplace. The outlet said this will make it easy for businesses with existing Google Cloud spending commitments to start using GPT models in place of whatever they used before. Google's system also supports moving workloads between models based on performance, latency and efficiency. Astra will cost the most to run, the report said.
OpenAI noted that Microsoft remains its primary cloud partner, Ars Technica reported.
The deal also gives Google Cloud customers another alternative to Google's own Gemini. Ars Technica reported that Google recently rolled out Gemini 4 Argon, which Google presents as bringing its flagship model back to parity with competitors. The outlet said the model looks like an improvement over Gemini 3.1 Pro but uses tokens at a very high rate.
Several details are still unclear. Antigravity has so far supported Gemini and Claude, and Google has not said which OpenAI models will be available there. Ars Technica suggested it may be the same three models, but this has not been confirmed. The report gives no specific dates for wider availability beyond the private preview and the "coming weeks" timeline for the Model Garden. It also does not describe the financial terms of the arrangement.
