Nano Banana Prompt Guide
Nano Banana (Google's Gemini 2.5 Flash image model, also called Nano Banana Pro) generates high-fidelity 4K stills with strong prompt control and consistent product detail. These prompts focus on the workflows creators ship most often on Kubricon: product photos, thumbnails, character references, brand assets, and image-to-video preparation. Generate the still, then animate it inside Kubricon's image-to-video flow.

Frequently asked questions
How does Nano Banana differ from Flux or Seedream?
Nano Banana is tuned for high-fidelity 4K stills with strong prompt control and consistent product detail. Flux 2 is stronger on photoreal portraits; Seedream is fast for iteration.
What output resolution does Nano Banana produce?
Nano Banana Pro generates up to 4K stills natively. Keep prompts specific about lighting and materials to take advantage of the resolution headroom.
Can I use Nano Banana stills as image-to-video sources?
Yes — Nano Banana is one of the cleanest image-to-video sources because of its consistent edges and detail. See the image-to-video prompt guide for motion-only prompts to pair with the still.
Are these prompts safe for commercial product photography?
Yes. Nano Banana generations on Kubricon are usable for product, brand, and ad work, subject to Google's and Kubricon's terms for the active plan.
Can I generate consistent characters across multiple Nano Banana images?
Use a detailed character reference in the first prompt and reuse the same description across subsequent prompts. Lock identity further with Kubricon's Reference Studio when you move to video.
