Check the [custom scripts](https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Custom-Scripts) wiki page for extra scripts developed by users.
## Features
[Detailed feature showcase with images](https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Features):
2022-09-04 10:08:06 +00:00
- Original txt2img and img2img modes
- One click install and run script (but you still must install python and git)
2022-09-04 10:08:06 +00:00
- Outpainting
- Inpainting
2022-10-01 00:15:43 +00:00
- Prompt Matrix
- Stable Diffusion Upscale
- Attention, specify parts of text that the model should pay more attention to
2022-10-01 00:15:43 +00:00
- a man in a ((tuxedo)) - will pay more attention to tuxedo
- a man in a (tuxedo:1.21) - alternative syntax
- Loopback, run img2img processing multiple times
- X/Y plot, a way to draw a 2 dimensional plot of images with different parameters
2022-09-04 10:08:06 +00:00
- Textual Inversion
- have as many embeddings as you want and use any names you like for them
- use multiple embeddings with different numbers of vectors per token
- works with half precision floating point numbers
2022-09-04 15:54:12 +00:00
- Extras tab with:
- GFPGAN, neural network that fixes faces
- CodeFormer, face restoration tool as an alternative to GFPGAN
- RealESRGAN, neural network upscaler
- ESRGAN, neural network upscaler with a lot of third party models
- SwinIR, neural network upscaler
2022-09-21 22:53:35 +00:00
- LDSR, Latent diffusion super resolution upscaling
2022-09-04 15:54:12 +00:00
- Resizing aspect ratio options
2022-09-04 10:08:06 +00:00
- Sampling method selection
- Interrupt processing at any time
- 4GB video card support (also reports of 2GB working)
- Correct seeds for batches
2022-09-04 10:08:06 +00:00
- Prompt length validation
2022-10-01 00:15:43 +00:00
- get length of prompt in tokens as you type
- get a warning after generation if some text was truncated
- Generation parameters
- parameters you used to generate images are saved with that image
- in PNG chunks for PNG, in EXIF for JPEG
- can drag the image to PNG info tab to restore generation parameters and automatically copy them into UI
- can be disabled in settings
2022-09-04 10:08:06 +00:00
- Settings page
2022-10-01 00:15:43 +00:00
- Running arbitrary python code from UI (must run with --allow-code to enable)
- Mouseover hints for most UI elements
2022-09-04 10:52:01 +00:00
- Possible to change defaults/mix/max/step values for UI elements via text config
- Random artist button
- Tiling support, a checkbox to create images that can be tiled like textures
- Progress bar and live image generation preview
- Negative prompt, an extra text field that allows you to list what you don't want to see in generated image
- Styles, a way to save part of prompt and easily apply them via dropdown later
- Variations, a way to generate same image but with tiny differences
- Seed resizing, a way to generate same image but at slightly different resolution
- CLIP interrogator, a button that tries to guess prompt from an image
- Prompt Editing, a way to change prompt mid-generation, say to start making a watermelon and switch to anime girl midway
- Batch Processing, process a group of files using img2img
- Img2img Alternative
- Highres Fix, a convenience option to produce high resolution pictures in one click without usual distortions
- Reloading checkpoints on the fly
- Checkpoint Merger, a tab that allows you to merge two checkpoints into one
- [Custom scripts](https://github.com/AUTOMATIC1111/stable-diffusion-webui/wiki/Custom-Scripts) with many extensions from community
