💼 OpenAI Expands to Google Cloud

The partnership announced on October 21, 2026, brings GPT-6 Astra, GPT-6.1 Sol, and GPT-6 Luna models, along with Codex agentic workflows, to Model Garden on Google Cloud, with sales facilitated through the Marketplace. Currently, this is available as a Private Preview for select enterprise clients, with general access promised within the coming weeks.

🌍 OpenAI is now operating simultaneously on the three largest US clouds—Microsoft, Amazon, and Google—although Microsoft remains its primary partner.

👤 If you work with GCP, OpenAI models and Codex workflows can be integrated directly into the Gemini platform, with billing handled through existing GCP commitments and Flexible Savings Plans, eliminating the need for a separate contract. Access is currently available by request via Private Preview.
