Here is an example for how to use Textual Inversion/Embeddings.

To use an embedding put the file in the models/embeddings folder then use it in your prompt like I used the SDA768.pt embedding in the previous picture.

Note that you can omit the filename extension so these two are equivalent:

embedding:SDA768.pt

embedding:SDA768

You can also set the strength of the embedding just like regular words in the prompt:

(embedding:SDA768:1.2)

Embeddings are basically custom words so where you put them in the text prompt matters.

For example if you had an embedding of a cat:

red embedding:cat

This would likely give you a red cat.
