OpenAI frontier models and Codex are coming to Google Cloud Model Garden and Marketplace (private preview now; GA in coming weeks); Antigravity and Gemini Agent next; Microsoft remains primary cloud partner

Why it matters

【Key points】

OpenAI and Google Cloud will put OpenAI frontier models and Codex into Model Garden, billed via Marketplace. Private preview now; GA in coming weeks. Microsoft remains OpenAI’s primary cloud partner.

1. Google Cloud names GPT-6 Astra, GPT-6.1 Sol, GPT-6 Luna. Usage draws down GCP commitments / Flexible Savings Plans on one invoice.

2. Also coming to Antigravity and Gemini Agent; Codex CLI/Desktop can point at the Gemini platform. Preview form is live.

3. Prompts/context/outputs stay in the customer perimeter and are not used to train foundation models; isolated gateways; ZDR and Confidential Compute “coming soon.”

4. Google Cloud says it is the only hyperscaler with OpenAI, Anthropic and Gemini closed-source frontiers on one platform — after OpenAI’s April AWS launch.

【Our read】

1. Background: After Microsoft IP exclusivity ended, OpenAI added AWS in April and now GCP. Azure stays primary; AWS/GCP are distribution so buyers use OpenAI where data and commit spend already sit.

2. Comparison: Anthropic already sells Claude on the big three; Gemini and Claude 5.5 are in Antigravity. With OpenAI on the same shelf, cloud differentiation shifts to residency, governance, commit drawdown and orchestration — not exclusive models. “Primary cloud partner” means distribution, not a training split from Microsoft.

3. Impact: helps GCP-committed teams wanting GPT-6 agents/coding; Google keeps workloads while Gemini competes side-by-side; softens Azure exclusivity premium and widens OpenAI’s enterprise surface. China availability unspecified.

4. Caveats: private preview; vague GA; no pricing/quotas; ZDR/Confidential Compute are roadmap; OpenAI news RSS had not indexed the post at fetch — use live blog.
