Google Ships Nano Banana 2.1 Image Model With Mask Editing

KEY FACTS

Google released its AI image model Nano Banana 2.1 on October 7.
The new version improves on three fronts: visual design, mask editing, and subject consistency.
Mask editing enables precise modification of local regions without regenerating the entire image.
The model is now live on the Gemini app, Google Search AI Mode, AI Studio, and other platforms.
Developers can use the model ID gemini-nano-banana-2.1, with support for 1K/2K/4K output.

PHYSIX OBSERVATION

Google is shifting the competitive focus of image editing from "generation quality" to "controllable editing" - masking and consistency are exactly the pain points designers hit every day. But the original also concedes that ChatGPT Images 2.5 still leads, meaning Google is catching up on iteration speed, not yet overtaking. For users, the simultaneous multi-platform rollout means the capability is available immediately and worth hands-on testing.
