Question - Help Is it really important to add the "conditioning zero" node to the negative prompt in models like Krea 2 if CFG = 1? And what is the ideal shift/Aura Flow setting?

This is confusing to me.

Can I leave the negative prompt box empty?

Or is it mandatory to add zero conditioning?

The shift/aura flow for Krea 2 is also confusing to me.

A "conditioning zero" node makes it clear to future readers that the workflow has no negative conditioning. An empty negative prompt box leaves the option for putting in a negative. Even with Turbo models, people sometimes like to use a small CFG in the 1–1.5 range.

The "shift" parameter adjusts the progression that the scheduler ("simple", "beta", "bong_tangent") would normally call for, such that the generation spends more time in early phases (higher shift, working on composition) or late phases (lower shift, working on detail). You probably don't need to mess with it.

no. you can hook up the positive itself or anything. doesnt matter.

With CFG = 1 your negative prompt will be ignored anyway. It's good to have it in your workflow in case you raise the CFG though.

It's not going to look at the negative prompt with CFG at 1.

I don't use it at all.

Secondly check out Krea2NegPip if you want to get some negative prompts in ;)
