Nano Banana 2.1 AI image generator

Create high-fidelity images with Nano Banana 2.1 at 1K, 2K, or 4K. Generate photos and stylized frames across eight aspect ratios in the Framings studio.

Best for

Nano Banana 2.1 is an AI image generator for stills that may need to go to 4K. It offers 1080p, 2K, and 4K, in 1:1, 16:9, 9:16, 4:3, and 3:4. Use it for campaign frames, character portraits, and detailed scenes you might later turn into a video.

Controls and pricing

Start with a concrete subject and a setting. An ember-lit portrait, a botanical astronaut, or a mechanical hummingbird gives the model a shape to hold. Add the light and the lens after the subject is clear. 4K is worth the extra credits when the image is already the one you want.

How to use it

Open Image and choose Nano Banana 2.1. Set the aspect ratio, pick 1080p while you explore, and write the prompt. When a composition works, generate it again at 2K or 4K. You can then upscale further or remove the background in the image tools.

Good to know

Each resolution has its own credit price on the Free plan, listed in the table. 4K costs more than 1080p. There is no 21:9 frame on this model. Flux 2 Pro and Seedream 5.0 include 21:9. Batches of up to four images are available on Power Studio.

Example prompts

  • Nano Banana 2.1 example: Create a photorealistic cinematic portrait of a woman in her thirties with freckles and windswept copper hair, wearing a heavy charcoal wool coat, turning her head toward the camera with a calm, intense gaze. She stands on an empty coastal cliff road at blue hour while warm sparks from a distant bonfire drift past her face. Medium close-up, subject centered with generous margin on all sides. Golden rim light from the right, cool teal ambient fill, shallow depth of field at f/1.8, 85mm lens, fine 35mm film grain, cinematic color grading. Widescreen 16:9.

  • Nano Banana 2.1 example: Generate a surreal editorial photograph of a single transparent glass apple tree growing in the middle of a calm salt flat at sunrise. Its branches hold glowing amber fruit that refract light into soft rainbow caustics on the white ground, and a mirror-still layer of water reflects the whole tree. Wide shot, tree perfectly centered, horizon at lower third, empty open sky around it. Soft pastel peach and lavender sky, crisp high-detail glass textures, medium-format photography look, quiet dreamlike mood. Widescreen 16:9 aspect ratio.

  • Nano Banana 2.1 example: Create a photorealistic underwater editorial photograph of a lone female freediver in a flowing ivory fabric suit suspended beside an enormous translucent moon jellyfish, its delicate filaments glowing electric blue. A cathedral of dark ocean water surrounds them, with a single shaft of sunlight from the surface illuminating suspended particles. Side-on wide composition, both subjects contained in the central two thirds with generous space around them. Natural anatomy, intricate translucent textures, restrained cyan and gold palette, premium nature photography, cinematic 35mm lens, widescreen 16:9. No typography or branding.
