# OpenAI models come to Google Cloud's Model Garden (GPT-6 Astra, GPT-6.1 Sol, GPT-6 Luna), making Google the only hyperscaler with all three leading closed model families

On Oct 21, 2026 Google Cloud added OpenAI's GPT-6 Astra, GPT-6.1 Sol and GPT-6 Luna to its Model Garden, billed through Google Cloud Marketplace, and OpenAI said its models and Codex workflows would also reach Google's Antigravity coding tool in the coming weeks. Google says it is now the only hyperscale cloud offering all three leading closed LLM families (Gemini, Claude, GPT). It follows OpenAI's April launch on AWS and further loosens its once-exclusive tie to Microsoft.

## Key facts
- Models (Google Cloud): GPT-6 Astra ('demanding work across coding, computer use, professional tasks, and scientific research'), GPT-6.1 Sol ('near-Astra intelligence at lower cost'), GPT-6 Luna (fast, cost-efficient)
- Google: 'Google Cloud is now the only hyperscale cloud provider offering access to all three leading closed source LLMs, alongside more than 200 first-party, third-party, and open models'
- Billing: transacted through Google Cloud Marketplace on one invoice; draws down existing cloud commitments and counts toward Flexible Savings Plans
- Data: prompts and outputs stay in the customer's perimeter and are not used for training; OpenAI models run on dedicated Google Cloud infrastructure; zero-data-retention and Confidential Compute 'coming soon'
- Antigravity: CNBC and Ars Technica headlines (not opened here) say the models reach Model Garden and Google's Antigravity coding tool 'in the coming weeks'; OpenAI X post (360k views): 'bringing our frontier models and Codex agentic workflows to Google Cloud's Model Garden'
- Hacker News: 294 points

## What happened

OpenAI's frontier models became available inside Google Cloud, the platform of its main model rival. Enterprises can now pick GPT,
Gemini or Claude models under one Google contract. The OpenAI announcement page returned HTTP 403 to our fetcher; details come from
Google's post and OpenAI's X post.

## Why it matters

The big model makers now sell through each other's clouds. For OpenAI it widens enterprise reach beyond Azure and AWS; for Google it
turns Vertex into a neutral marketplace even for its biggest competitor.
