Google is introducing Nano Banana 2, a new image generation model that pairs the capabilities of the pricier Pro model with the speed of Gemini Flash. It's set to become the default in the Gemini app.
Technically, image generation runs on the new multimodal Gemini 3.1 Flash Image model. Google says it combines the advanced capabilities of Nano Banana Pro, which shipped in November, with the speed of the Flash model series.
Google says the model draws on Gemini's knowledge base and pulls real-time information and images from web searches to render subjects more accurately. Just like Nano Banana Pro, it can also create infographics, turn notes into diagrams, and generate data visualizations.
Nano Banana 2 cuts API costs by up to 40 percent
Google says it improved instruction following so the model handles complex prompts more precisely. On the specs side, Nano Banana 2 supports multiple aspect ratios and resolutions ranging from 512 pixels up to 4K. Google also promises more vivid lighting, richer textures, and sharper details compared to the original Nano Banana.
