Nano Banana 2
Google · AI imageNano Banana 2, also known as Gemini 3.1 Flash Image, is Google's latest AI image generation model. It combines Pro-level capabilities with Flash-style speed: higher resolution (up to 4K widescreen), better character consistency (up to five characters in one workflow), and accurate text in images. Google has positioned it as replacing both standard and Pro variants of earlier image models in many contexts.
When you need publication-ready visuals—thumbnails, hero frames, and standalone images—with the best balance of quality and speed in the Google image lineup, Nano Banana 2 is the flagship Flash-tier choice. It leverages mixture-of-experts and advanced quantization so that generation stays fast while quality reaches Pro levels.
The model can draw on Gemini's knowledge base and optional real-time search to create accurate infographics and detailed subject renderings. That makes it suitable for content that references real-world facts, places, or current events, as well as for creative and branded imagery.
Key features and benefits
Resolution and range
Nano Banana 2 supports output from 512 pixels up to 4K widescreen, so you can match the resolution you need for different platforms and print. Generation remains fast thanks to efficient architecture—mixture-of-experts activates only relevant pathways per prompt, and quantization reduces weight size without large quality loss.
Character consistency
The model can render up to five characters consistently within a single workflow, which helps with serial content, storyboards, and multi-panel visuals where the same people or characters appear.
Accurate text in images
Nano Banana 2 generates legible, accurate text inside images, addressing a common limitation of earlier AI image models. That makes it suitable for infographics, captions, and branded graphics where words must be readable and correct.
Object rendering
It can accurately render many different objects in one workflow (e.g. up to around 14), with good composition and detail for product shots and complex scenes.
Efficiency and knowledge
The model uses mixture-of-experts and quantization for faster generation without sacrificing quality, and can draw on Gemini's knowledge and optional search for accurate, up-to-date subject matter.
