Enterprises with committed Google Cloud spending are getting another way to pay for OpenAI models: through Google Cloud Marketplace, using budgets they have already committed to Google.
In Google Cloud’s October 21 announcement, GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna are entering Model Garden in private preview for selected enterprise customers. The preview also supports connecting local Codex CLI and Desktop workflows to Google’s platform for inference.
Access is restricted. Integrations with Google Antigravity and Gemini for business are still coming, and some advertised security capabilities will not be available at the outset.
Even with those limits, the competitive shift is substantial. Google is becoming a purchasing and deployment channel for models that compete with its own Gemini offerings. OpenAI gains another enterprise distribution route while, according to OpenAI, Microsoft remains its primary cloud partner.
Private Preview Comes Before the Broader Rollout
Selected enterprise customers can begin using the three OpenAI models through Google’s APIs and connect their local Codex workflows to its platform. Other interested customers must register their interest; access is not unrestricted.
The rollout has several distinct stages:
- Starting now: Private-preview access to GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna for selected enterprises.
- Supported during the preview: API access and connections from local Codex CLI and Desktop workflows to Google’s platform for inference.
- Still ahead: OpenAI model availability inside Google Antigravity and Gemini for business.
- Not yet generally available: The broader offering, which OpenAI says is planned for the coming weeks without specifying a launch date.
Google calls the forthcoming business integration “Gemini for business,” while OpenAI refers to the Gemini Agent. Neither reference establishes that the integration is available today.
The Codex support also has limits. Connecting a local CLI or Desktop workflow to Google’s inference service gives developers a way to use those interfaces with a cloud-backed model endpoint. The model does not run locally. That support also does not establish that every Codex feature is included or that the forthcoming Antigravity integration is operational.
Buyers first need to confirm whether their organization can enter the preview and whether it supports their required workflow. A planned general release offers no guarantee of current access.
