About "Nano Banana"
What is Nano Banana
Nano Banana is the nickname for Google (Google DeepMind)'s Gemini image generation and editing model. "Nano Banana" refers to Gemini 2.5 Flash Image (released August 26, 2025), which went viral for editing images in natural language while keeping characters consistent. The higher-end "Nano Banana Pro" is Gemini 3 Pro Image (released November 2025).
Nano Banana is available via the Gemini app, Google AI Studio, the Gemini API, and Vertex AI. Nano Banana Pro is also integrated into Google Workspace (Slides, Vids), Google Ads, NotebookLM, and Search's AI Mode. Generated images carry the "SynthID" invisible watermark. Because there are many copycat sites like "nanobanana.ai" that are NOT official Google, use it only through the official surfaces above.
How to use
Generate and edit from a prompt in the Gemini app or studio.
Open an official surface
Use the Gemini app, AI Studio, or the API.
Generate from a prompt
Generate an image from text; you can also provide reference images.
Edit in conversation
Do local edits and blends in chat, e.g. "change the background."
Export
Save the image (with a SynthID watermark). Pro supports up to 4K.
The Gemini app's free tier has daily usage limits. When exceeded, it is described as falling back to standard Nano Banana (exact limits are undisclosed).
Key features
01Generation and conversational editing
Beyond text-to-image, it supports local editing over multiple conversational turns (background changes, object removal, pose changes, etc.). A key strength is editing while keeping people and characters consistent.
02Fusion and in-image text (Pro)
Nano Banana Pro is strong at fusing multiple images (up to 14 inputs, keeping up to 5 people consistent) and rendering legible, multilingual text within images, making it suitable for posters and mockups. It also supports camera-angle, lighting, and color-grade edits.
03Resolution and SynthID
Nano Banana (2.5 Flash Image) outputs around 1024px by default, while Nano Banana Pro supports 1K/2K/4K and multiple aspect ratios. Every generated image carries the "SynthID" invisible watermark.
Pricing
In the Gemini app it's usable via a free tier plus paid subscriptions; developers use it via usage-based API pricing.
| Type | Price | Notes |
|---|---|---|
| Gemini app (free) | $0 | Daily limits apply |
| Google AI paid plans | AI Plus $4.99 / Pro $19.99 / Ultra $99.99 (monthly) | Higher limits |
| API: 2.5 Flash Image | $0.039/image | Batch is half price |
| API: 3 Pro Image | 1K/2K $0.134, 4K $0.24 (per image) | Also on Vertex AI |
The API bills by output tokens; the table above is a per-image guide. The exact daily image quotas for each app plan are not published. Prices are in USD and subject to change; check the official pricing page and Gemini's official site for the latest (as of August 2026).
How it differs from other image-generation AIs
Nano Banana stands out by being part of Gemini, strong at character-consistent conversational editing, multi-image fusion, and in-image text rendering. Its character differs from general generators focused on aesthetic style, or services that emphasize rights compliance.
| Aspect | Nano Banana | Midjourney | Adobe Firefly |
|---|---|---|---|
| Focus | Conversational generation/editing (Gemini) | High-quality image generation | Commercially-conscious generation/editing |
| Strength | Consistency, fusion, text rendering | Style, expressiveness | Adobe integration, rights care |
| Provider | Midjourney | Adobe |
Midjourney, known for high-quality style; Adobe Firefly, whose strength is commercial-use consideration; and Google's own Whisk make good points of comparison. If you want to edit existing images in conversation while keeping consistency, Nano Banana is a strong option.
