Introduction to Textual Inversion Embeddings in Stable Diffusion
Textual inversion embeddings have become very popular in the Stable Diffusion community recently. They allow you to easily customize the style and quality of images generated by Stable Diffusion models. In this blog post, we will provide an overview of textual inversion embeddings, discuss their capabilities and limitations, and provide guidance on how to use existing embeddings as well as create your own.
Textual inversion embeddings contain learned representations that encode information about a specific visual style. By adding the name of the embedding to your prompt, you instruct Stable Diffusion to render images that match that style. This works very similarly to class-conditional guidance in other generative models.
Stable Diffusion 2.1 Limitations
The Stable Diffusion 2.1 model generates decent images, but they tend to be a bit boring and generic. Textual inversion embeddings can help overcome these limitations by providing control over the precise style of generated images.
Textual Inversion Embeddings Overview
Textual inversion embeddings are small files that contain encoded information about a visual style. They allow full customization of the style and quality of AI-generated images in Stable Diffusion 2.0 and 2.1.
Using Existing Textual Inversion Embeddings
Many textual inversion embeddings created by the Stable Diffusion community are available for download. These embeddings encode a wide variety of visual styles ranging from specific artists to animation studios and aesthetic styles. Here we provide guidance on finding, adding, and using existing embeddings.
Where to Find Embeddings
Great resources for finding textual inversion embeddings include sites like Civitai and Hugging Face. Look for embeddings tagged as compatible with Stable Diffusion 2.0/2.1. Some top creators to check out are ShadowXShinigami and confixx.
Downloading and Adding Embeddings
Once you've identified embeddings you want to use, download the .pt files and add them to the /embeddings folder in your Stable Diffusion setup. Restart SD and the new embeddings will be automatically loaded and ready for use.
Using Embeddings in Prompts
To use a textual inversion embedding, simply add its name to your prompt. For example, "a scenic landscape sunset, by Viking Punk". Stable Diffusion will render the image to match the style encoded in the embedding. You can combine multiple embeddings for unique mixes.
Creating Your Own Textual Inversion Embeddings
With the right GPU, you can also train your own textual inversion embeddings using Stable Diffusion's built-in tools. This allows you to fully customize SD's output style. Here we provide an overview of the process for creating embeddings.
Setup and Configuration
Navigate to the Train tab in Stable Diffusion and select "New Embedding" to begin. Choose embedding size, learning rate, and other training parameters wisely.
Pre-processing Images
Upload a dataset of images representing the style you want to encode. Stable Diffusion will auto-crop and create text captions for each image to improve training.
Training the Embedding
With your dataset pre-processed, start the embedding training run. Monitor the training and stop when image quality stops improving. The final embeddings will be saved automatically.

FAQ
Q: What are textual inversion embeddings?
A: Textual inversion embeddings are small files that contain trained data from a neural network. When added to Stable Diffusion, they allow modifying the image generation style and quality.
Q: Do I need a powerful GPU to use embeddings?
A: No, you can use existing textual inversion embeddings without any special GPU requirements. However, training your own embeddings does require a GPU with at least 12GB of VRAM.
Q: How do I add embeddings to Stable Diffusion?
A: Download embedding files and place them in your Stable Diffusion /embeddings folder. The next time you launch SD, they will be automatically loaded and available.
Q: Can I combine multiple embeddings?
A: Yes, one of the best features of textual inversion embeddings is the ability to mix and match them. Just include multiple embedding keywords in your prompt.
Q: Do old embeddings work on SD 2.1?
A: No, embeddings need to be specifically trained on SD 2.0/2.1 to be compatible. Older embeddings trained on SD 1.4/1.5 will not work.
