OpenAI's GPT 6.1 models Astra, Sol, Luna head to Google Cloud

The arrangement marks a notable shift in cloud AI competition. Google Cloud's Model Garden already offers access to Google's Gemini models, open models like Mistral, Llama, and Gemma, and Anthropic's Claude AI. With OpenAI's GPT models added, Google says it is now the only large cloud provider offering access to all three leading closed LLMs. For OpenAI, the deal expands its enterprise reach beyond Microsoft, which remains its primary cloud partner, while Google gains a draw for customers who want flexibility in choosing models. Astra will cost the most to run among the OpenAI models, but Google's system supports dynamically moving workloads between LLMs based on performance, latency, and efficiency, which may help businesses optimize usage.
