ZDNET’s key takeaways
- The new Nano Banana 2 promises better image generation.
- The new model aims to produce high‑quality images much faster.
- Nano Banana 2 is now the default model across all Google apps and sites.
Last year Google made a big splash in the world of AI‑powered image creation with its Nano Banana model. Now the next generation has debuted, promising a host of enhancements for generating photos, drawings, diagrams, infographics, and other images for individuals, professionals, and businesses alike.
On Thursday Google announced Nano Banana 2 (officially dubbed Gemini 3.1 Flash). Accessible to free and paid users, the new model replaces the first Nano Banana everywhere—it’s now the default on the Gemini website and app, Google Search, Google Flow, AI Studio, and the Gemini API for developers.

What makes the second banana so much better than the first? (According to Google)
-
Advanced world knowledge – Nano Banana 2 uses Gemini’s real‑world knowledge and images from web searches to create images more accurately. This helps the AI devise infographics, turn notes into diagrams, and visualize data.
-
Consistency – Previous AI image generators often struggled to keep characters and objects consistent across multiple images. Nano Banana 2 can keep up to five characters and 14 objects consistent through each iteration.
-
Better text rendering – Generating legible text in AI images has been hit‑or‑miss. Nano Banana 2 aims for more accurate, readable text—useful for greeting cards, ad mockups, and even translating text within an image for multilingual variations.
-
Better at following your instructions – Complex prompts sometimes confuse AI generators. Nano Banana 2 captures tone and nuance more reliably, delivering images that match the intended description.

-
Faster speeds – Earlier generations forced a trade‑off between quality and speed (e.g., Nano Banana Pro vs. Nano Banana Flash). The new version combines high quality with faster generation times.
-
Higher fidelity – Images now feature sharper details, richer textures, and more vibrant lighting—all while running more quickly than before.
-
Production‑ready quality – Need a logo, infographic, or advertisement? Nano Banana 2 lets you control aspect ratio and set resolution anywhere from 512 px up to 4 K, ensuring the output is ready for professional use.
Hands‑on testing

Prompt 1 – Text rendering & layout
“A vintage‑style travel poster for a lunar colony on the Moon. In the center, a sleek 1950s‑style rocket is landing near a glass dome. At the top, in a bold, cream‑colored Art Deco font, render the words ‘VISIT LUNAR CITY.’ At the bottom, in smaller but clear script, add the phrase ‘The Gateway to the Stars.’ Use a palette of deep navy, muted orange, and silver. High resolution, professional graphic design style. Use a 16:9 aspect ratio and create the image in 1080p.”
The resulting image captured the correct style and font, followed the color palette, aspect‑ratio, and resolution specifications.

Prompt 2 – Character consistency
First request
“Create a character sheet for ‘Captain Nova,’ a female space explorer with short, bright purple hair, a glowing blue mechanical eyepiece over her left eye, and a silver‑and‑white flight suit with a gold sun emblem on the chest.”
(Further prompts and results continue in the original article.)
Nano Banana 2 Character Sheet & Scene
Prompt:
“Show her from the front, side, and back against a plain grey background. Create the image in a 21:9 aspect ratio at 4K.”
The AI followed the instructions and produced a sheet that displayed the character and highlighted several key details.

Next Prompt:
“Using the same character of Captain Nova, show her running through a neon‑lit cyberpunk market. She is looking over her shoulder with a determined expression, her purple hair wind‑blown. Keep her mechanical eyepiece and the gold sun emblem on her suit exactly the same. Cinematic lighting, shallow depth of field. Again, keep the image in a 21:9 aspect ratio at 4K.”
The result kept the character consistent in style and appearance, so she looked the same in both images.

Takeaway
Based on these prompts, Nano Banana 2 appears to be a worthwhile upgrade over the prior generation. It is now the default across the board. Google AI Pro and Ultra subscribers can still use the legacy Nano Banana Pro for more specialized tasks, while anyone else can try out the latest “flavor” of the new banana to see what images it “unpeels.”
