How to Install & Add Nano Banana to Photoshop: The Official Guide

Go to Replicate

Visit replicate.com and click Sign in.

Sign in with GitHub

Click Sign in with GitHub. If you do not have a GitHub account yet, create one during the login process.

Open Account settings

After signing in, click your profile picture and choose Account settings.

Add credit

In Account settings open Billing. Click Add credit and add at least $10. Current costs per image: about $0.039 for Nano Banana, $0.04 for Flux Kontext Pro and $0.08 for Flux Kontext Max. A ten dollar deposit is plenty to test the plugin.

Disable auto reload

Click Manage auto reload and make sure auto reload is disabled to avoid unwanted charges.

Create an API token

In Account settings open API tokens. Create a new token and copy it. You will paste this token in Photoshop later.

Open the script

Open any document, then go to File → Scripts → FluxKontext.

Configure settings

The first time you open the script, the Settings will open first. Paste your Replicate API token.

Choose a model

When you're done, choose a model: Nano Banana: with options for Foreground Color and Reference Image (only on macOS). Flux Kontext: context-aware edits, typography, and lighting.

Make a selection

Make a selection in Photoshop using any selection tool.

Open the script

Go to File → Scripts → Nano-Banana-Flux-Kontext.

Enter a prompt

Enter a short, specific prompt describing what you want to generate.

Choose model and generate

Choose a model: Nano Banana: with options for Foreground Color and (on macOS) Reference Image. With Reference image, you can insert an image in your selection. Flux Kontext: context-aware edits, typography, and lighting. Click Generate. The result appears as a new layer on top of your original.

Keyboard shortcut

Assign a keyboard shortcut (Edit → Keyboard Shortcuts). I use Cmd-Shift-K. In the Keyboard Shortcuts section, navigate to File > Scripts > Nano-Banana-Flux-Kontext, click in the field next to it and type your preferred shortcut.

Prompt guidelines

Keep prompts short and specific. Mention material, color, lighting. Prompts in Flux Kontext need to be more specific than Nano Banana.

Selection tips

Make selections slightly larger or softer to give the models more context.

Model recommendations

Try both Flux Kontext Pro and Max: Pro is great for most cases, Max can be stronger on typography. My preferred method is Nano Banana nowadays, except for changing the environmental lighting, and blending objects.

Creative techniques

Try drawing a sketch, and then let Nano Banana make something out of it. I had very impressive results. Use Upscale if the generated area feels too small or soft.
