What Nano Banana is good at — and what it's not

Nano Banana is Google's original image model in the line — the fast, affordable default for everyday image work. It's cheap enough to iterate freely, and its strength is breadth: prompt-driven generation, reference-guided edits, and the kind of quick stills that fill social posts, blog headers, and mockups. When you need an image now and don't need the highest fidelity, this is the model.

Consistency comes from up to 10 reference images. Feed a character sheet, a palette, or a product shot and Nano Banana holds that subject across a run — enough for simple storyboards, recurring mascots, and product mockups where the same item has to reappear. Output spans ten aspect ratios, from 21:9 cinematic to 4:5 portrait, so one prompt set covers feed, story, and banner formats.

Where it's weaker: it has no resolution dial and sits below the newer tiers on raw fidelity. For higher resolution and stronger text rendering, step up to Nano Banana 2; for the highest-end factual and reference work, Nano Banana Pro; for photoreal portraits, Flux 2 Pro. Nano Banana's sweet spot is cheap, fast, everyday generation.

A reasonable mental model: default to Nano Banana for quick, low-cost images and iteration, and step up to Nano Banana 2 or Pro when a deliverable needs more resolution, text accuracy, or factual grounding.
