Nano Banana (Gemini 2.5 Flash): Fast generation with strong consistency
Simply enter your Google AI Studio API key and use the generative fill feature directly within a Photoshop editor version 2018 or newer, installed only on Windows 64-bit, without any intermediaries, whether it is connected to the cloud or not.
Your selection is sent to Google AI studio models and the result is placed back as a new layer, keeping lighting, shadows, and materials consistent.
Because the AI models run on Google AI studio, you'll need to create a free account there.
What will I receive?
You will receive a JSX file that can be easily installed in the scripts folder on your computer. After installation, you will be able to call up the generative window which allows you to make edits using AI.
Is image generation free?
Image generation uses cloud APIs, such as Google AI Studio, so it costs money and requires generating an API key through Google AI Studio ([https://aistudio.google.com/api-keys](https://aistudio.google.com/api-keys)). This is a simple process that is easy to complete.
Can I use my Google Gemini subscription?
Yes, you can.
Do I need a Graphics Processing Unit (GPU)?
No. A GPU is not required. Image generation is handled by cloud APIs.
Are there any minimum requirements?
To install the new script, you need a version of Photoshop no earlier than 2018.
