Both are Google image models available on Sevli. Nano Banana 2 corresponds to Gemini 3.1 Flash Image; Pro corresponds to Gemini 3 Pro Image. Compare the controls, credits and task requirements before choosing.
Which should you choose?
Start with Nano Banana 2 when its 15-credit 1K quote fits your task. Try Pro at 30 credits for the same 1K setup when you want to assess detailed instructions or controlled edits. Both expose up to 4K and six references here; Pro is not required just to choose 4K.
Table quotes are for one image at 1:1, Medium where available. A different ratio, quality, image count or number of references can change the quote. Check the composer before submitting.

Create a premium product advertisement: a single cream ceramic tea canister on a light beige studio surface, soft side lighting and subtle green tea leaves. Include exactly the large headline "SPRING TEA" and smaller text "FRESH EVERY DAY". Preserve generous whitespace. Square composition.
Create a beautifully detailed isometric cutaway illustration of a colorful creative studio, with four rooms clearly connected in a single building: an art studio with easels and paint, a photo studio with a camera and softboxes, a reading nook with books and a sofa, and a rooftop garden with plants. Rendered like an exquisite hand-crafted architectural model with rich terracotta, sage green, dusty blue and sunny yellow materials. Small fictional fully clothed adult figures give scale. Place the exact Chinese title 创意工作室 across the top, and four clean short labels beside the appropriate rooms: 画室, 摄影, 阅读, 花园. Crisp legible typography, generous separation of labels from objects, rich detail and polished lighting. No other lettering, no logos. Horizontal 4:3 composition.
A breathtaking surreal editorial image: one enormous luminous red-and-white koi fish slowly swimming through the air above a futuristic coastal city at blue hour. The fish is gracefully curved, its translucent fins flowing like silk; windows and elevated walkways glow amber below, deep indigo skyscrapers fade into mist, a small crescent moon overhead. Dreamlike but convincingly photographed, sophisticated teal, coral and indigo palette, shimmering water particles suspended in the sky, cinematic scale and balanced composition. No text, no logos. Horizontal 4:3 composition.
Keep the prompt, aspect ratio, resolution and reference images the same. Inspect text accuracy, subject consistency and composition, then compare the displayed credit quote. Test output sizes shared by both models; a single image is not a reliable quality ranking.
