What is Nano Banana 2?

📐 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.
