Generated by Nano Banana 2 Prompt: "A photo of a glossy magazine cover, the minimal blue cover has the large bold words Nano Banana. The text is in a serif font and fills the view. No other text. In front of the text there is a portrait of a person in a sleek and minimal dress. She is playfully holding the number 2, which is the focal point.
Put the issue number and "Feb 2026" date in the corner along with a barcode. The magazine is on a shelf against an orange plastered wall, within a designer store." -
Generated by Nano Banana Pro Prompt: "Present a clear, 45° top-down isometric miniature 3D cartoon scene of London, featuring its most iconic landmarks and architectural elements. Use soft, refined textures with realistic PBR materials and gentle, lifelike lighting and shadows. Integrate the current weather conditions directly into the city environment to create an immersive atmospheric mood. Use a clean, minimalistic composition with a soft, solid-colored background. At the top-center, place the title "London" in large bold text, a prominent weather icon beneath it, then the date (small text) and temperature (medium text). All text must be centered with consistent spacing, and may subtly overlap the tops of the buildings." -
Generated by Nano Banana 2 Prompt: "Use image search to find accurate images of a resplendent quetzal bird. Create a beautiful 3:2 wallpaper of this bird, with a natural top to bottom gradient and minimal composition." -
Generated by Nano Banana Pro Prompt: "Put this logo on a high-end ad for a banana scented perfume. The logo is perfectly integrated into the bottle." -
Generated by Nano Banana Pro Prompt: "A photo of an everyday scene at a busy cafe serving breakfast. In the foreground is an anime man with blue hair, one of the people is a pencil sketch, another is a claymation person" -
Generated by Nano Banana Pro Prompt: "Use search to find how the Gemini 3 Flash launch has been received. Use this information to write a short article about it (with headings). Return a photo of the article as it appeared in a design focused glossy magazine. It is a photo of a single folded over page, showing the article about Gemini 3 Flash. One hero photo. Headline in serif." -
Generated by Nano Banana Pro Prompt: "An icon representing a cute dog. The background is white. Make the icons in a colorful and tactile 3D style. No text." -
Generated by Nano Banana 2 Prompt: "Make a photo that is perfectly isometric. It is not a miniature, it is a captured photo that just happened to be perfectly isometric. It is a photo of a beautiful modern garden. There's a large 2 shaped pool and the words: Nano Banana 2."
Nano Banana is the name for Gemini's native image generation capabilities. Gemini can generate and process images conversationally with text, images, or a combination of both. This lets you create, edit, and iterate on visuals with unprecedented control.
Nano Banana refers to four distinct models available in the Gemini API:
- Nano Banana 2 Lite (Gemini 3.1 Flash Lite Image)
(
gemini-3.1-flash-lite-image): Our fastest and cheapest Gemini image model, engineered for velocity and scale where speed and cost are the primary operational constraints. Not optimized for multiple reference inputs or multi-turn sequential editing. - Nano Banana 2 (Gemini 3.1 Flash Image)
(
gemini-3.1-flash-image): Serves as the most versatile model, generalist workhorse model for all tasks. It balances speed with state-of-the-art 4K generation, world knowledge, and reliable text rendering. Excelling at multiple reference image processing and consistency. - Nano Banana Pro (Gemini 3 Pro Image)
(
gemini-3-pro-image): The premium choice for the most complex visual tasks, offering the highest level of world knowledge, advanced localization, accurate brand consistency, and precision creative control. - Nano Banana (Gemini 2.5 Flash Image)
(
gemini-2.5-flash-image): The legacy pioneer of the Nano Banana series. While it has been a reliable workhorse, we strongly recommend that customers transition to Nano Banana 2 Lite to experience enhanced quality, faster generation speeds, and lower API pricing.
All generated images include a SynthID watermark.
