Nano Banana 2.1, Google's newest image model, is now in the image generator. Pick it from the model list. Nano Banana 2 stays available, and nothing you made before changes.
What is different
Google says 2.1 follows prompts more closely, keeps the same character steadier across edits and gets text and infographic layouts right more often. It also fixes the seams that could show on very wide and very tall images.
What you can do with it
- Make images at 1K, 2K or 4K.
- Upload up to 10 reference images and describe how to combine or change them.
- Go past the usual shapes: wide 4:1 and 8:1 strips, and tall 1:4 and 1:8 banners.
The Nano Banana 2.1 page shows real test results with their prompts, and the side-by-side test against GPT Image 2.5 shows which jobs suit which model.
