Google Cloud Unifies GPT-6, Claude, and Gemini on Single Invoice for Enterprise

Google Cloud says it is making enterprise procurement simpler by funneling multiple closed-source AI model families through a single billing invoice in its Model Garden. The move adds OpenAI’s GPT-6 variants to the platform in private preview for select customers, including GPT-Astra for advanced software engineering and research, GPT-6.1 Sol for agentic coding at lower cost, and GPT-6 Luna for fast, cost-efficient high-volume tasks. Sign-ups are open, with general availability expected within weeks. Google also lists OpenAI’s Codex agent as part of the rollout. Google confirmed customer data won’t be used to train hosted models and frames its billing and data-perimeter controls as enterprise-ready.
