# What it costs

> Fulla is free; you pay the AI service per image, from about 5 cents, and the panel shows the cost of every run.

Fulla itself is free. You pay the AI service you connected, **per image**: no subscription, no monthly credits that expire.

## How much is an image?

It depends on the model and the size. With Nano Banana 2.1, the recommended model, measured in November 2026:

| Size | Price per image |
| --- | --- |
| 1K | about $0.05 |
| 2K | about $0.06 |
| 4K | about $0.12 |

## Where do I see the cost?

After each run, the card shows the cost of the run and of the session (since the panel was opened). With OpenRouter, it is the exact amount billed.

## Keep spending under control

When you connect with OpenRouter, you can set a **spending limit** and an expiry date for the key on openrouter.ai. A few dollars of credit go a long way: $5 is about 100 images.
