Nano Banana in Photoshop

Nano Banana is the name of Google’s Gemini image models. There are two ways to use them for generative fill in Photoshop: through Adobe’s own generative fill, paid in credits, or through Fulla, a free plugin, paid per image to the AI service you connect.

With Photoshop’s generative fill

Adobe offers Nano Banana 2 and Nano Banana Pro as partner models in Photoshop’s generative fill. A fill uses 20 credits with Nano Banana 2 (30 at 4K) and 40 with Nano Banana Pro, from your plan’s monthly allowance. See Photoshop generative credits, explained.

With Fulla

Fulla is a free, open-source Photoshop plugin. Its recommended model is Nano Banana 2.1; it also offers Nano Banana Pro and, with a Google key, Nano Banana 2 Lite. You pay per image, about 5 cents for Nano Banana 2.1 at 1K or 2K, and see the cost of each run in dollars.

Model in Fulla	Through OpenRouter	With a Google key
Nano Banana 2.1 (recommended)	Yes	Yes
Nano Banana Pro	Yes	Yes
Nano Banana 2 Lite	No	Yes

Set up Nano Banana in Photoshop with Fulla

1. Install Fulla in Photoshop 2026 (27.11 or later).
2. Open Plugins > Fulla and click Connect with OpenRouter, or add a Google (Gemini API) key. See First run.
3. Nano Banana 2.1 is already selected. Select an area, describe what you want, and click Generate.

With a Google key, billing must be turned on in your Google account: Gemini’s free tier allows no image generation.

Which one should I use?

If your plan gives you more credits than you use, Adobe’s tool costs you nothing more. If you run out of credits, want to see what each image costs, or want models Photoshop doesn’t offer, Fulla lets you pay only for the images you make. See Fulla vs Photoshop’s generative fill.
