Nano Banana 2 is Google's state-of-the-art AI image generation model designed for creating and editing images with Pro-level capabilities combined with lightning-fast speed. This model represents a major update from Google, specifically identified as Gemini 3.1 Flash Image, focusing on delivering high-quality visual outputs efficiently.

The model offers advanced world knowledge powered by Gemini and real-time web search grounding for accurate subject rendering. Key capabilities include rapid edits and iteration with Gemini Flash speed, stronger instruction following for better adherence to complex prompts, and accurate text rendering with localization support. It maintains subject consistency across up to 5 characters while preserving fidelity of up to 14 objects, and delivers production-ready visuals with richer lighting, textures, and sharper details.

Nano Banana 2 operates with context-aware generation that leverages Gemini's capabilities for intelligent image creation. The model supports flexible aspect ratios and resolution control from 512px to 4K, eliminating the need for heavy post-processing or upscaling hacks. It combines real-world knowledge with real-time web search data to create hyper-niche visuals and accurate renders of specific subjects.

The benefits include fewer retries and more predictable outputs critical for production workflows, making it suitable for marketing creatives, infographics, greeting cards, and global campaigns. Use cases span storyboarding, ad sequences, brand mascots, UI continuity, and high-frequency pipelines such as bulk UGC ad creation or generating consistent frames for video models.

Target users include marketing professionals, content creators, and developers working with visual content. The model integrates across Google's ecosystem including Google Ads, Google Antigravity, Vertex AI, Search AI Mode & Lens, Flow, AI Studio, Gemini API, and the Gemini app. It features provenance with SynthID watermarking and upcoming C2PA Content Credentials support, with over 20 million SynthID verifications already conducted.
