Google Unveils Nano Banana 2 to Standardize 4K AI Imaging Across Gemini

Google announced Nano Banana 2, an image-generation model powered by Gemini 3.1 Flash Image that dramatically increases generation speed while preserving the predecessor's world knowledge and fidelity. Key enhancements include maintaining consistent appearance for up to five characters, improved on-canvas text rendering, support for up to 4K output, stricter adherence to complex instructions, and deployment across Google Search AI Mode, Google Lens, Flow AI Creative Studio, and the Gemini App (replacing Nano Banana Pro for most users while retaining Pro access for paid tiers).
