Overview
Nano Banana is the name of Google’s image models in Gemini. It creates an image from a description or edits one you upload. To change it, simply describe what you want: the light, the camera angle, the setting, a specific detail.
Several versions live side by side:
- Nano Banana 2: the default model, free in Gemini with limits.
- Nano Banana 2.1: Google’s most advanced image model (quality, reasoning, visual design), for Google AI subscribers.
- Nano Banana Pro: the “high definition” version, also found in tools such as Kittl.
Its strengths: legible text inside images (logos, posters, invitations, in many languages), combining several reference images, keeping a character consistent across scenes, and resizing to any format without losing detail.
Pros
- Free to start, right inside Gemini.
- Edit by describing the change, no manual selection.
- Text in images far more reliable than most competitors.
- Multiple references in one image: a product and a setting, for example.
Cons
- Fidelity to brand guidelines is not guaranteed: check colours, shapes and typefaces.
- Limited resolution on the free tier (1K).
- Version names change fast and are confusing.
- Images carry an invisible SynthID watermark; copyright and image rights still apply.
Studio Elias’s recommendation
Nano Banana is for testing brand visuals, not for publishing without checks. It is excellent for exploring a direction, staging a product or adapting a visual to many formats. Before publishing, compare each image with your guidelines, proofread any text it contains and check your rights. If you don’t have clear guidelines yet, start there: AI amplifies an identity, it doesn’t create one.
