What each model is good at, where it differs from the others, and what it costs to run.
Google's general-purpose Gemini image model. Open it when a Visxy library prompt already describes the picture and you want a finished frame, not a thumbnail.

Nano Banana 2 is the model you open when you already know the picture and have not made it yet. Google's name for it is Gemini 3.1 Flash Image: the generalist in the Nano Banana line. On Visxy it is the default for a library prompt you are ready to commit to — the paragraph of subject, lens, light and wardrobe, not a thumbnail test.
If you are still shopping looks, use Nano Banana 2 Lite first. If the frame has to survive being stared at — a headline inside the picture, a label, a dense layout — skip this page and go to Nano Banana Pro.
Long, specific prompts. Visxy's image prompt library is written that way on purpose. Banana 2 tends to keep the extra named object when you add a fifth, which is why it is the better default for a full scene than for a single isolated subject. A studio portrait with a set, a window-pane shadow, and clothes that have to read as fabric is this model's work; a five-word mood board is Lite's.
It is also the family member for frames Lite cannot finish. Banana 2 and Pro both let you pick a larger output. Lite does not. If you already like a Lite still and the only problem is that it is too small, re-run the same prompt here rather than rewriting it.
Instruction-following is the other reason to be here. Naming a lens, a film stock, or which way the light falls actually moves the picture. That is why a copied Visxy prompt usually gets you closer on Banana 2 than the same prompt mashed into keyword soup.
Against Nano Banana 2 Lite: different model, not a quality slider. Lite is Flash Lite; this is Flash. Lite has no size control and is the wrong place for stacked references or long edit chains. Banana 2 is the one that can go larger and the one to attach several stills to when a face or a product has to survive the edit.
Against Nano Banana Pro: Pro is the SKU for maximum factual accuracy and studio control. Banana 2 is the one Google tells developers to start with. On Visxy that maps onto the library: most 9:16 portraits should live here. Pro is the exception you open for type-heavy or inspect-me frames.
Banana 2 (and Lite) can do the ultra-wide frames Pro does not offer. If the deliverable is a panoramic banner or an extreme strip, this is the page — Pro physically cannot make that shape. Do not "fix" that by generating 16:9 on Pro and cropping.
Describe the scene, then the light, then the style. That order matches how the library prompts are written. If you write style first ("cinematic, 8k, ultra detailed") the model fills in a generic handsome face and ignores the set.
Write what should be there. Negative instructions ("no text", "no extra fingers") are less reliable than omitting the thing. If the prompt includes a headline, spell the headline. Banana 2 will attempt lettering; it is not Pro. Short words in a clear frame work more often than a paragraph on a magazine cover.
Use 9:16 when you came from the image library. Use a wide frame when the prompt is actually a landscape or a banner — including the ultra-wide ones Pro cannot do. auto is reasonable when you care about the subject more than the crop.
If a Lite draft already has the pose and the light, do not "improve" the prose. Paste the same prompt here.
We have not yet published a Visxy wall-clock for Banana 2. Other hosts still report waits on the order of tens of seconds, not the two-second Lite playground clip. Treat "Flash" as a family name, not a promise.
Editing is this model with a reference attached — there is no public Nano Banana 2 Edit article. Say the change: "overcast sky, keep the wardrobe." "An overcast day" reads as a new picture.
This is the Banana you use when the edit refers to something the model cannot infer: a face to keep, a product to place, a style to match. Attach those stills; one reference is the common case. Lite is the wrong place to start a multi-still identity lock.
It edits. It does not restore. Missing detail will be invented.
For a finished Visxy library still, yes. Start on Lite only when you are still choosing among looks. Start on Pro only when the prompt is type-heavy or has to survive a close look.
No. Banana 2 is Gemini 3.1 Flash Image. Pro is Gemini 3 Pro Image. Same family, different contracts: Pro has no ultra-wide frames, and it is the SKU for inspect-me work.
Because Lite is cheaper to be wrong on, and it has no size picker to tempt you into a large file of a bad crop. Draft the pose there; re-run keepers here.
Attach a reference to this model and describe the change. There is no separate Edit page to find. Use Banana 2 rather than Lite when the change has to honour a face or a product you attached.
