Gemini 3.7 Flash rolls out to Pro and Ultra users; Spark now runs on it too

Gemini 3.7 Flash 全面上线 Pro 与 Ultra 用户

Gemini 3.7 Flash is now live for Pro and Ultra subscribers in Gemini chat. Google claims better multi-step reasoning and accuracy—e.g., merging dozens of files and emails into one master doc. Gemini Spark also moved to 3.7 Flash, with improved tool calling across Google Workspace apps. The post doesn't say when free-tier users will get access.

Why it matters: Gemini 3.7 Flash GA for Pro/Ultra with Spark upgrade is a concrete Google ecosystem update with real use cases. No benchmarks or latency numbers disclosed, so it stays below 85, but the multi-step reasoning and tool-calling accuracy claims carry signal for practitioners.
