Somewhat modular text2image GUI, initially just for Stable Diffusion.

Relies on a slightly customized fork of the InvokeAI Stable Diffusion code (formerly lstein): Code Repo

• GPU: Nvidia GPU with 4 GB VRAM, Maxwell Architecture (2014) or newer
• RAM: 8 GB RAM (Note: Pagefile must be enabled as swapping will occur with only 8 GB!)
• Disk: 12 GB (another free 2 GB for temporary files recommended)

• GPU: Nvidia GPU with 8 GB VRAM, Pascal Architecture (2016) or newer
• RAM: 16 GB RAM
• Disk: 12 GB on SSD (another free 2 GB for temporary files recommended)

• GPU: Nvidia GPU with 24GB VRAM, Turing Architecture (2018) or newer
• RAM: 32 GB RAM
• Disk: 12 GB on NVME SSD (another free 25 GB for temporary files recommended), system-managed paging file enabled

• Multiple prompts at once: Enter each prompt on a new line (newline-separated). Word wrapping does not count towards this.

• Negative Prompt: Put words or phrases into this box to tell the AI to exclude those things when generating images.

  • Alternatively, you can also put the negative prompt into the regular prompt box by wrapping it in [brackets].

• Emphasis: Use + after a word/phrase to make it more impactful, or - to do the opposite. You can also use to increase the effect. Wrap your phrase in parentheses if you want to apply it to more than one word.

  • Each plus/minus applies a multiplier of 1.1. So two +++ would be 1.1^3 = 1.331, and so on.
  • You can also type the strength manually after parentheses, e.g. a (huge)1.33 dog instead of a huge+++ dog
  • Examples: a green++ tree, a (big green)+ tree with orange- leaves (in the woods)++

• Wildcards: Fill in words or phrases from a list into the prompt.

  • Inline: photo of a ~car,tree,dog~.
  • From File: photo of a ~objects for loading texts from objects.txt in your Wildcards folder in the SD GUI root folder.
  • Order: Use ~ for random/shuffled, ~~ for unchanged order, or ~~~ for sorted (A-Z) mode.

• Load Image(s): Load an initialization image that will be used together with your text prompt ("img2img")

  • Loading multiple images means that each image will be processed separately, in sequence.

• Load Concept: Load a Textual Inversion concept to apply a style or use a specific character

• Steps: More steps can increase detail, but only to a certain extend. Depending on the sampler, 20-60 is a good range.

  • Has a linear performance impact: Doubling the step count means each image takes twice as long to generate.

• Prompt Guidance (CFG Scale): Lower values are closer to the raw output of the AI, higher values try to respect your prompt more accurately.

  • Use low values if you are happy with the AI's representation of your prompt. Use higher values if not - but going too high will degrade quality.
  • No performance impact, no matter the value.

• Seed: Starting value for the image generation. Allows you to create the exact same image again by using the same seed.

  • When using the same seed, the image will only be identical if you also use the same sampler and resolution (and other settings).
  • Lock Seed Option: Disable incrementing the seed by 1 for each image. Only useful in combination with wildcards.

• Resolution: Adjust image size. Only values that are divisible by 64 are possible. Sizes above 512x512 can lead to repeated patterns.

  • Higher resolution images require more VRAM and are slower to generate.
  • High-Resolution Fix: Enable this to avoid getting repeated patterns at high resolutions (~768px+). Can reduce fidelity though.

• Sampler: Changes the way images are sampled. Euler Ancestral is the default because it's fast and tends to look good even with few steps.

• Generate Seamless Images: Generates seamless/tileable images, very useful for making game textures or repeating backgrounds.

• Review current images: Use the scroll wheel while hovering over the image to go to the previous/next image.
• Slideshow: The image viewer always shows the newest generated image if you haven't manually changed it in the last 3 seconds.
• Context Menu: Right-click into the image area to show more options.
• Pop-Up Viewer: Click into the image area to open the current image in a floating window.
  • Use the mouse wheel to change the window's size (zoom), right-click for more options, double-click to toggle fullscreen.

• Image Generation Implementation: Chose the AI implementation that's used for image generation.

  • Stable Diffusion - InvokeAI: Supports the most features, but struggles with 4 GB or less VRAM, requires an Nvidia GPU
  • Stable Diffusion - OptimizedSD: Lacks many features, but runs on 4 GB or even less VRAM, requires an Nvidia GPU

• Use Full Precision: Use FP32 instead of FP16 math, which requires more VRAM but can fix certain compatibility issues.

• Unload Model After Each Generation: Completely unload Stable Diffusion after images are generated.

• Stable Diffusion Model File: Select the model file to use for image generation.

  • Included models are located in Data/models. You can add more folder paths by clicking on "Folders...".

• Stable Diffusion VAE: Select external VAE (Variational Autoencoder) model. VAEs can improve image quality.

• CUDA Device: Allows your to specify the GPU to run the AI on, or set it to run on the CPU (very slow).

• Image Output Folder: Set the folder where your generated images will be saved.

• Output Subfolder Options:

  • Subfolder Per Prompt: Save images in a subfolder for each prompt. Negative prompt is excluded from the folder name.
  • Ignore Wildcards: Use wildcard name (as in prompt input) instead of the replaced text in file/folder names.
  • Subfolder Per Session: Save images in a subfolder for each session (every time the program is started).

• Favorites Folder: Specify your favorites folder, where your favorite images will be copied to (right-click image viewer or use Ctrl+D)

• Metadata to Include in Filename: Specify which information should be included in the filename.

• When Running Multiple Prompts, Use Same Starting Seed for All of Them: If enabled, the seed resets to the starting value for every new prompt. If disabled, the seed will be incremented by 1 after each iteration, being sequential until all prompts/iterations have been generated.

• When Post-Processing Is Enabled, Also Save Un-Processed Image: When enabled, both the "raw" and the post-processed image will be saved.

• Advanced Mode: Increases the limits of the sliders in the main window. Not very useful most of the time unless you really need those high values.

• Notify When Image Generation Has Finished: Play a sound, show a notification, or do both if image generation finishes in background.

• Open Logs Folder: Opens the log folder of the current session. The application deletes logs older than 3 days on every startup.
• Copy <logname>.txt: Copy one of the log files generated in the current session to clipboard.

• Installation Status: Shows which modules are installed (checkboxes are not interactive and only indicate if a module is installed correctly!).
• Redownload SD Model: Re-downloads Stable Diffusion 1.4 model (4 GB) from Google Storage servers.
• Re-Install SD Code: Re-installs the Stable Diffusion code from its repository. Can fix some issues related to file paths.
• Re-Install Upscalers: (Re-)Installs upscaling files (RealESRGAN, GFPGAN, CodeFormer, including model files).
• (Re-)Install: Installs everything. Skips already installed components.
• Uninstall: Removes everything except for Conda which is included and needed for a re-installation.

• Open Stable Diffusion CLI: Use Stable Diffusion in command-line interface
• Open CMD in Conda Environment: Opens a CMD window with the built-in conda python environment activated.
• Merge Models: Allows you to merge/blend two models. The percentage numbers represent their respective weight.
• Prune Models: Allows you to reduce the size of models by removing data that's not needed for image generation.
• View Log In Realtime: Opens a separate window that shows all log output, including messages that are not shown in the normal log box.
