Nano Banana 2 was announced by Google on February 26, 2026 as part of the Gemini model family. Unlike its predecessor (Nano Banana Pro, based on Gemini 3 Pro), NB2 uses the Gemini 3.1 Flash architecture — optimized for speed without sacrificing output quality.
Core Capabilities
📐 Resolution: 512px to 4K
Nano Banana 2 supports four resolution tiers, including a 512px quick-preview mode exclusive to NB2 that's not available in any other Gemini image model.
🌐 Web-Grounded Generation
Nano Banana 2 can access real-time web information during image generation via Google Search integration. This means it can reference current events, real brand logos, trending styles, and up-to-date visual concepts that earlier models would hallucinate or miss. Activated via tools: [{ googleSearch: {} }] in the API.
🖼️ 14 Reference Images
For image editing and multi-image blending tasks, NB2 accepts up to 14 reference images simultaneously. This enables complex creative workflows: style transfer from multiple sources, product photography with scene references, and character-consistent storytelling across many frames.
👤 Character Consistency (Up to 4)
NB2 can maintain consistent character appearance across up to 4 characters in a single generation session. This is critical for e-commerce product models, brand mascots, comic/manga creation, and any workflow that requires recognizable faces across multiple outputs.
📏 14 Aspect Ratios
Beyond the standard ratios, Nano Banana 2 introduces exclusive ultra-wide and ultra-tall formats ideal for panoramic shots, social media stories, banner ads, and cinematic compositions.
