Google Cloud announced that OpenAI models are now available in its model garden, positioning itself as the only hyperscale cloud provider offering access to all three leading closed-source LLM families alongside more than 200 first-party, third-party, and open models on a unified enterprise AI platform. The move extends Google Cloud‘s strategy of giving customers flexibility to run agentic workloads across multiple models and infrastructure choices rather than relying on a single model for every task.

The newly available OpenAI models are GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna. GPT-6 Astra is designed for demanding work across coding, computer use, professional tasks, and scientific research. GPT-6.1 Sol targets agentic coding, computer use, and professional work at a lower cost while delivering near-Astra intelligence. GPT-6 Luna is described as a fast, cost-efficient model for everyday work at scale. Through Google Cloud‘s platform, customers can dynamically select and swap the optimal model for each workload based on performance, latency, and cost efficiency, avoiding architectural lock-in or separate vendor contracts.

OpenAI models are transacted directly through Google Cloud Marketplace, so usage appears on a single Google Cloud invoice, draws down existing cloud commitments, and counts toward Flexible Savings Plans across model providers. Developers can build with hundreds of model choices in model garden while keeping procurement and billing consolidated.

Google Cloud emphasizes enterprise governance for third-party and OpenAI workloads. Customer prompts, context, and outputs remain within the customer’s designated data perimeter and are never used to train foundation models, with Zero Data Retention options coming soon. OpenAI models run on dedicated Google Cloud infrastructure with Confidential Compute coming soon, and all queries are routed through hardened, isolated gateways so data transit stays within Google Cloud‘s secure environment. Unified auditing and identity controls give administrators end-to-end visibility, VPC Service Controls protection, and unified audit logging across all agent and model interactions.

The OpenAI models are rolling out now in private preview to select enterprise customers in Google Cloud‘s model garden, with more models coming soon. Customers can start building through Google Cloud‘s APIs and connect local Codex CLI and Desktop workflows to the Gemini platform for inference. Google Cloud also says OpenAI models will soon be available in Gemini for business and Google Antigravity, extending model choice to those products as well.
