OpenAI's GPT-6 models and Codex come to Google Cloud in private preview

OpenAI’s frontier models are coming to Google Cloud. Both companies announced it on 21 October: OpenAI’s post covers the partnership, and Google’s post has the details builders need.

What is live and what is not

Item	Status, per the two posts
GPT-6 Astra, GPT-6.1 Sol, GPT-6 Luna in Model Garden	Private preview, rolling out to select enterprise customers
API access and Codex CLI or Desktop using Google for inference	“Starting today”, for preview customers
General availability	Planned “in the coming weeks” (OpenAI)
Gemini for business or Gemini Agent, Google Antigravity	“Coming soon”
Zero data retention option, Confidential Compute	“Coming soon” (Google)
Prices	Not listed in either post

When we checked this afternoon, Google’s OpenAI models docs page still listed only the open-weight gpt-oss-120b and gpt-oss-20b, so expect the setup docs to arrive with wider access.

Why the billing line matters

Google says OpenAI usage is sold through Google Cloud Marketplace, shows up on the same Google Cloud invoice, draws down existing cloud commitments and counts toward Flexible Savings Plans. For many companies that is the real barrier: the money is already committed to one cloud, and a new vendor contract takes months. OpenAI’s post says the same about commitments.

Google also describes the data handling: prompts and outputs stay inside the customer’s perimeter and are not used for training, the models run on dedicated Google Cloud infrastructure, and access sits under VPC Service Controls and unified audit logs. Those are Google’s statements, and two of the stronger guarantees are still marked as coming soon.

Context

Google calls itself the only hyperscaler that now offers all three leading closed model families. OpenAI’s post closes by noting that “Microsoft remains OpenAI’s primary cloud partner.” On AWS, OpenAI already powers Amazon Bedrock Managed Agents, which entered public preview in late September.

If you want in now, both posts point to a request form. Otherwise, wait for GA and the price sheet before planning a migration.
