Nano Banana 3.1 Flash, the lightweight tier. Faster and cheaper than Pro, tuned for bulk generation and quick iteration. Use when you need a lot of images (thumbnails, avatars, concept variants) at lower per-unit cost. If the result is not quite right, there is no need to re-upload anything: just type another instruction in the same conversation, such as "change the background to night" or "translate the text to English", and the previously generated image is reused automatically for continuous refinement; you can also upload other pictures in the same conversation as references for editing the previous result. Generated images are about 1024x1024 (1K resolution); the aspect ratio adjusts automatically to your prompt or reference image.
