Real generations with Nano Banana Pro 2 (Gemini 3.1)
Overview
Nano Banana Pro 2 is the Gemini 3.1 generation of Google's image model, and its defining skill is obedience: it follows composition and text instructions more literally than any sibling in the FluxoKit catalog. FluxoKit runs it in the browser with credit pricing and no Google AI Studio setup.
Every image on this page is a real, unretouched Nano Banana Pro 2 generation with the exact prompt printed under it. The nano banana name gets enormous attention; this page is the capability proof behind it, typography stress-tests included.
What you can build with Nano Banana Pro 2
When the artwork must contain words, Nano Banana Pro 2 is the first pick: posters where the headline is generated inside the frame, packaging concepts with legible labels, and promo graphics where a price or date has to come out exactly as written. Quote the text in the prompt and it renders clean at 2K.
The second strength is layout control. Describe where things go, such as product left, headline top right, negative space bottom, and Pro 2 respects the geometry. The gym flyer in the shared brief above is the live demonstration.
Where Nano Banana Pro 2 earns its credits
Marketing teams use Pro 2 for finished promo graphics that would otherwise need a designer pass for the type layer. Product teams use it for UI-adjacent mockups where labels must read. At 12 credits per default 2K image, with 6-credit 512px drafts and 18-credit 4K finals available, the tier ladder is visible on every generation in your history.
Nano Banana Pro 2 vs Nano Banana Pro, GPT Image 2, and FLUX 2 Flex
The previous generation stays the volume choice at a lower rate. Pro 2 upgrades instruction-following and text stability; run the same prompt on both pages to see the delta.
GPT Image 2 reads better as photography and costs 7 credits. Pro 2 wins when composition and in-image text must land exactly as specified.
Flex is the typography specialist in the FLUX.2 family. Pro 2 matches it on text legibility while following scene-level layout instructions more literally.
