How to Fine-tune Prompts In Comfy UI

In Comfy UI, you have several ways to fine-tune your prompts for more precise results:

  • Up and Down Weighting: You can emphasize certain parts of your prompt by using the syntax (prompt:weight). For instance, for the prompt "flowers inside a blue vase," if you want to focus more on the flowers, you could write (flowers:1.2) inside a blue vase. Nested brackets multiply the weights.
  • Textual Inversion Embeddings: Utilize custom CLIP embeddings by incorporating them into your prompt with embedding:name, where 'name' is the embedding file's name.
  • Random Choices: Let ComfyUI randomly select from options in your prompt using {choice1|choice2|...} syntax. For example, "a {red|blue|yellow|green} flower."

You can adjust these settings directly in the prompt interface or use shortcuts like Ctrl+Up and Ctrl+Down to modify weights.
