OpenAI's frontier models and Codex agentic workflows are now available in Google Cloud's Model Garden, according to an announcement from OpenAI on October 21, 2026. This partnership expands the accessibility of OpenAI's models to enterprise customers, allowing them to integrate these tools into their existing Google Cloud infrastructure. Google Cloud stated it is now the only hyperscale cloud provider offering access to Gemini, Claude, and GPT models on a unified enterprise AI platform.
The integration enables Google Cloud customers to purchase OpenAI models through the Google Cloud Marketplace, with transactions drawing down existing Google Cloud spend commitments. This provides a streamlined procurement process and consolidated billing for businesses. OpenAI emphasized that the collaboration aims to provide native access to its models, supporting complex agentic workflows at scale, while benefiting from Google Cloud's data governance and high-performance infrastructure.
For organizations in regulated industries, the partnership addresses requirements for data control and usage. The integration pairs OpenAI's frontier models with Google Cloud's built-in access controls and centralized data governance. OpenAI models will also become available in Google Antigravity and the Gemini Agent, offering enterprise customers greater flexibility in model selection for various tasks.
The models currently rolling out in private preview to select enterprise customers include GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna. OpenAI plans general availability in the coming weeks. GPT-6 Astra is designed for demanding tasks in coding, computer use, professional applications, and scientific research. GPT-6.1 Sol provides similar intelligence at a lower cost, while GPT-6 Luna is a fast, cost-efficient model for everyday large-scale operations.
Despite this expansion, OpenAI clarified that Microsoft remains its primary cloud partner. The move to Google Cloud follows Amazon Web Services hosting OpenAI models starting in April, after OpenAI's exclusive agreement with Microsoft concluded. This strategic decision by OpenAI allows it to reach customers across all three major U.S. cloud providers. Greg Brockman, OpenAI's president and co-founder, stated that the partnership is an important step in making their models available where customers are already building. Thomas Kurian, CEO of Google Cloud, noted that the focus is on offering customers a broad selection of models to ensure the right tool for each job, aiming for optimal quality and reduced costs.
