Features

Prompt Toggle node

The conditioning/helpers/Prompt Toggle node is similar to conditioning/CLIP Text Encode (Prompt), but enhanced with new features:

• It supports BREAK which splits a single large prompt into multiple chunks.

  • Many models like SDXL have a limit of 75 tokens per prompt. You can use BREAK to split a large prompt into smaller chunks, which means you can now have more than 75 tokens in your prompt.

  • You can use BREAK to prevent concepts from bleeding. For example, you can use a prompt like this:

    1girl,
    blue_eyes,
    dress,
    
    BREAK
    
    1boy,
    green_eyes,
    jacket,
    

    Because the BREAK splits the prompt into two separate chunks, this helps the AI to understand that the blue_eyes and dress belong to the girl, and the green_eyes and jacket belong to the boy.

  • You can use BREAK to separate your prompt into different sections (quality, background, artist style, composition, etc.)

    // Quality tags
    masterpiece,
    best quality,
    
    BREAK
    
    // Character tags
    1girl,
    1boy,
    
    BREAK
    
    // Composition tags
    absurdly_detailed_composition,
    dutch_angle,
    
    BREAK
    
    // Background tags
    sky,
    outside_border,
    
    BREAK
    
    // Artist tags
    konpeto,
    null_\(nyanpyoun\),
    tomoshibi_hidekazu,
    

    This clean separation can help the AI better understand different elements of the image.

• For each line in the prompt, it displays a checkbox which makes it very easy to enable or disable that line.

• For each line in the prompt, it displays the weight, and a - and + buttons which make it very easy to increase or decrease the weight of that line.

• It automatically cleans up the prompt, keeping it clean and readable, and preventing unnecessary tokens.

You can have multiple tags per line, making it easy to enable / disable the entire tag group, or you can put each tag onto a separate line.

You can also have freeform text, such as An anime illustration of a girl and boy. They are standing next to a tree, with the sky in the background.
