Editing Images

You can use image models to edit images by selecting an area of the image to edit and describing the desired changes. The model will generate the edited image based on your description. This tutorial demonstrates how to edit images in GPUStack.

Prerequisites

Before you begin, ensure that you have the following:

  • A GPU with at least 24 GB of VRAM.
  • Access to Hugging Face for downloading the model files.
  • GPUStack is installed and running. If not, refer to the Quickstart Guide.

In this tutorial, we will use the FLUX.1-Fill-dev model in Q8_0 quantization to edit images.

Step 1: Deploy the Model

Follow these steps to deploy the model from Hugging Face:

  1. Navigate to the Catalog page in the GPUStack UI.
  2. Search and select the FLUX.1 Fill Dev model.
  3. In the popup, select the Q8_0 quantization.
  4. Leave everything as default and click the Save button to deploy the model.

Deploy Model

After deployment, you can monitor the model's status on the Models page.

Step 2: Use the Model to Edit Images

  1. Navigate to the Playground > Image page in the GPUStack UI.
  2. Click the Edit tab on the top
  3. Verify that the deployed model is selected from the top-right Model dropdown.
  4. Upload the example image by clicking the center upload area.
  5. Draw a mask over the hair area of the example image.
  6. Input the following text prompt in the Text Prompt field: 
    Pink short hair bang, natural
  7. Click the Submit button to generate the edited image.

Image Edit Input

The generated image will be displayed in the UI. Your image may look different given the seed and randomness involved in the generation process.
