Google AI weekly product updates: Nano Banana 2, Co-Scientist, dreambeans, Gemma 4, and more

Google AI 本周产品更新：Nano Banana 2、Co-Scientist、dreambeans、Gemma 4 等

Google AI announced six updates: Nano Banana 2 is generally available, Gemma 4 12B can run fully offline on laptops, and Magenta RealTime 2 is open source.

Why it matters: HKR-H/K/R all pass: the post bundles six Google AI updates with concrete local and open-source hooks. Lacking benchmarks, licensing, and pricing keeps it below the 78+ good-quality band.
