Google Nano Banana 2: Fast AI Art with Character Consistency

Google's Nano Banana 2 is the fastest image generation model on SeniAI. It combines conversational editing, multi-image fusion, and character consistency into a model that generates images in seconds.

If you need to iterate quickly on concepts, create consistent character art across multiple scenes, or generate images based on real-world context, Nano Banana 2 is your go-to model.

What Makes Nano Banana 2 Special

1. Conversational Editing

Unlike traditional text-to-image models where you start fresh each time, Nano Banana 2 supports a conversational approach. Upload an existing image and describe changes:

"Make the background a sunset instead of daytime"
"Change her outfit to a school uniform"
"Add cherry blossoms falling in the scene"

This makes iteration dramatically faster compared to re-prompting from scratch.

2. Multi-Image Fusion

Upload up to 14 reference images and Nano Banana 2 will intelligently blend elements from all of them. This enables:

Character consistency - Upload 5 views of your character, generate new poses
Style mashups - Combine elements from different art styles into one cohesive image
Product variations - Upload a product and generate it in different settings

3. Google Search Grounding

A unique feature: Nano Banana 2 can use Google Web Search and Google Image Search as context for generation. This means you can:

Generate images of current events (sports scores, weather)
Create visuals based on real-world references without uploading images
Ground your generations in factual, up-to-date information

How to Create Consistent Characters

Here is a step-by-step workflow for creating a character that looks the same across multiple images:

Step 1: Create Your Character Sheet

Start with a detailed prompt:

"Anime girl with short blue hair, green eyes, wearing a white sailor uniform with blue ribbon, chibi style, clean white background, character reference sheet showing front view"

Step 2: Upload as Reference

Download your character sheet image, then upload it as a reference image when generating new scenes.

Step 3: Generate New Scenes

With your character reference uploaded, prompt new scenarios:

"Same character sitting in a Japanese classroom, looking out the window at cherry blossoms, warm afternoon light"

"Same character at a festival, wearing a yukata, holding cotton candy, fireworks in the background"

The multi-image reference system ensures your character's features stay consistent across all generations.

Best Prompts for Nano Banana 2

Nano Banana 2 excels with concise, clear prompts. Unlike Seedream 5 Lite which handles complex descriptions well, Nano Banana 2 prefers directness:

Good prompt:

"Kawaii cat sticker, big sparkly eyes, pink bow tie, sitting on a crescent moon, pastel background, cute"

Also works well:

"Product photo of handmade soap bars, lavender and oat, rustic wooden surface, soft natural light"

Social media content:

"Instagram story template, minimalist aesthetic, soft gradients, quote placeholder, modern typography space"

Resolution & Points

Resolution	Points	Best For
1K (default)	5 points	Social media, quick concepts
2K (max)	8 points	Final artwork, detailed illustrations

Nano Banana 2 at 2K produces excellent results for most use cases. For print or large-format needs, switch to Seedream 4.5 (4K).
