this is my workflow.

Just ComfyUI's node requires negative value. stop_at_clip_layer = -2 is equivalent to clipskip = 2

@ltdrdata thanku! very helpful. I setted clip skip, but still can not really get a approximate result as the model announced,

this is I got:

I have using 30 steps, generate, same prompt, and I scaled, the result like oil painint, but this is what I want:

Can u see why?

Your token weights are too high. You should not give weights same with A1111.

[lucasjinreal]

@ltdrdata hi, how to set the token weights can u elebrate? Do u mean cfg? from the webiste it says using 7.0,

does there any a calculate formate between A1111 and comfyui? How?

[lucasjinreal]

@ltdrdata You might know magic, bro!

up and down weighting¶

The importance of parts of the prompt can be up or down-weighted by enclosing the specified part of the prompt in brackets using the following syntax: (prompt:weight). E.g. if we have a prompt flowers inside a blue vase and we want the diffusion model to empathize the flowers we could try reformulating our prompt into: (flowers:1.2) inside a blue vase. Nested loops multiply the weights inside them, e.g. in the prompt ((flowers:1.2):.5) inside a blue vase flowers end up with a weight of 0.6. Using only brackets without specifying a weight is shorthand for (prompt:1.1), e.g. (flower) is equal to (flower:1.1). To use brackets inside a prompt they have to be escaped, e.g.\(1990\). ComfyUI can also add the appropriate weighting syntax for a selected part of the prompt via the keybinds Ctrl+Up and Ctrl+Down. The amount by which these shortcuts up or down-weight can be adjusted in the settings.

Thank you this was very confusing for me to find this setting!

@lucasjinreal Can you share your workflow, I'd like to learn how to use clip step layer.

for anyone else wondering, the node is called CLIPSetLastLayer found under Conditioning

what is clipskip what does it do whats the different betweern no clip skip to -1 -2 0 1 2 etc and please show photo comparrsion examples ty

@Amit30swgoh, sometimes when you download a model (checkpoint), in the notes the author recommends some settings. Often 'clip skip' is one of them. Unless you want to get down to the level of expertise where you're editing your own models, you probably wouldn't mess with it otherwise.
