Nano Banana 2: Google's latest AI image generation model - Lightning-Fast 4K AI Image Generation with Pro-Level Quality
Google has launched Nano Banana 2, officially called Gemini 3.1 Flash Image, combining the advanced capabilities of Nano Banana Pro with the speed of Gemini Flash. This new model generates images from 512px to 4K resolution in approximately 5-6 seconds while maintaining character consistency across up to five characters and object fidelity for up to 14 reference objects. The model is now the default across Gemini's modes and has achieved first place on LM Arena's text-to-image leaderboard with an ELO score of 1,280.
Overview
Nano Banana 2 represents a significant leap in AI image generation technology, addressing two critical needs: professional-quality output and rapid generation speed. Unlike traditional diffusion-based models, Nano Banana 2 is natively multimodal, leveraging Gemini's real-world knowledge base powered by real-time information from Google Search. This enables more accurate rendering of specific subjects, legible text generation, and precise instruction following—all delivered in near real-time.
