Google releases Nano Banana 2.1: AI image generation evolves again
Google has released Nano Banana 2.1, bringing capability upgrades including 4K upscaling, mask editing and 14-image fusion, and moving AI image generation into a more precise and controllable stage.
Key points
- 4K output: Generation resolution rises to 4K, greatly improving detail and practical value.
- Mask editing: Supports local inpainting and precise modifications, moving AI image generation from “gacha-style rerolling” to “fine retouching.”
- 14-image fusion: Styles and elements from up to 14 images can be blended into one creation, opening up new creative possibilities.
Thanks to its strong instruction following and editing abilities, the Nano Banana series has become one of the benchmarks in AI image generation. The 2.1 update widens the distance from its pursuers even further.
