# Image Generation
|
|
|
|
Open WebUI supports image generation through three backends: **AUTOMATIC1111**, **ComfyUI**, and **OpenAI DALL·E**. This guide will help you set up and use either of these options.
|
|
|
|
## AUTOMATIC1111
|
|
|
|
Open WebUI supports image generation through the **AUTOMATIC1111** [API](https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/API). Here are the steps to get started:
|
|
|
|
### Initial Setup
|
|
|
|
1. Ensure that you have [AUTOMATIC1111](https://github.com/AUTOMATIC1111/stable-diffusion-webui) installed.
|
|
2. Launch AUTOMATIC1111 with additional flags to enable API access:
|
|
```
|
|
./webui.sh --api --listen
|
|
```
|
|
3. For Docker installation of WebUI with the environment variables preset, use the following command:
|
|
```
|
|
docker run -d -p 3000:8080 --add-host=host.docker.internal:host-gateway -e AUTOMATIC1111_BASE_URL=http://host.docker.internal:7860/ -e ENABLE_IMAGE_GENERATION=True -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main
|
|
```
|
|
|
|
### Configuring Open WebUI
|
|
|
|
1. In Open WebUI, navigate to the **Admin Panel** > **Settings** > **Images** menu.
|
|
2. Set the `Image Generation Engine` field to `Default (Automatic1111)`.
|
|
3. In the API URL field, enter the address where AUTOMATIC1111's API is accessible:
|
|
```
|
|
http://<your_automatic1111_address>:7860/
|
|
```
|
|
If you're running a Docker installation of Open WebUI and AUTOMATIC1111 on the same host, use `http://host.docker.internal:7860/` as your address.
|
|
|
|
## ComfyUI
|
|
|
|
ComfyUI provides an alternative interface for managing and interacting with image generation models. Learn more or download it from its [GitHub page](https://github.com/comfyanonymous/ComfyUI). Below are the setup instructions to get ComfyUI running alongside your other tools.
|
|
|
|
### Initial Setup
|
|
|
|
1. Download and extract the ComfyUI software package from [GitHub](https://github.com/comfyanonymous/ComfyUI) to your desired directory.
|
|
2. To start ComfyUI, run the following command:
|
|
```
|
|
python main.py
|
|
```
|
|
For systems with low VRAM, launch ComfyUI with additional flags to reduce memory usage:
|
|
```
|
|
python main.py --lowvram
|
|
```
|
|
3. For Docker installation of WebUI with the environment variables preset, use the following command:
|
|
```
|
|
docker run -d -p 3000:8080 --add-host=host.docker.internal:host-gateway -e COMFYUI_BASE_URL=http://host.docker.internal:7860/ -e ENABLE_IMAGE_GENERATION=True -v open-webui:/app/backend/data --name open-webui --restart always ghcr.io/open-webui/open-webui:main
|
|
```
|
|
|
|
### Configuring Open WebUI
|
|
|
|
1. In Open WebUI, navigate to the **Admin Panel** > **Settings** > **Images** menu.
|
|
2. Set the `Image Generation Engine` field to `ComfyUI`.
|
|
3. In the API URL field, enter the address where ComfyUI's API is accessible:
|
|
```
|
|
http://<your_comfyui_address>:8188/
|
|
```
|
|
Set the environment variable `COMFYUI_BASE_URL` to this address to ensure proper integration.
|
|
|
|
## OpenAI DALL·E
|
|
|
|
Open WebUI also supports image generation through the **OpenAI DALL·E APIs**. This option includes a selector for choosing between DALL·E 2 and DALL·E 3, each supporting different image sizes.
|
|
|
|
### Initial Setup
|
|
|
|
1. Obtain an [API key](https://platform.openai.com/api-keys) from OpenAI.
|
|
|
|
### Configuring Open WebUI
|
|
|
|
1. In Open WebUI, navigate to the **Admin Panel** > **Settings** > **Images** menu.
|
|
2. Set the `Image Generation Engine` field to `Open AI (Dall-E)`.
|
|
3. Enter your OpenAI API key.
|
|
4. Choose the DALL·E model you wish to use. Note that image size options will depend on the selected model:
|
|
- **DALL·E 2**: Supports `256x256`, `512x512`, or `1024x1024` images.
|
|
- **DALL·E 3**: Supports `1024x1024`, `1792x1024`, or `1024x1792` images.
|
|
|
|
## Using Image Generation
|
|
|
|
|
|
|
|
1. First, use a text generation model to write a prompt for image generation.
|
|
2. After the response has finished, you can click the Picture icon to generate an image.
