"Very good image model" Posted 2026-10-06
Pros: The text rendering is also noticeably better. Infographics, posters, UI-style graphics, and anything with labels or typography come out cleaner and need less manual fixing afterward. I really like the multi-reference support too. Being able to use up to 14 reference images gives me much more control when I am trying to preserve specific people, products, objects, or visual styles across a project.
Cons: The main downside is that it can still get spatial details wrong occasionally, especially things like left versus right, and Google says advanced 3D reasoning and factuality still have limitations.
Overall: Overall, Nano Banana 2.1 feels like a meaningful upgrade rather than a minor refresh. It is fast enough to iterate with constantly, but the better editing, text, reference consistency, 4K output, and optional thinking make it capable enough for much more serious design and content work.
