Self-Guidance

[v0xie]

An attempt at implementing https://arxiv.org/abs/2412.05827
The implementation currently is coupled with PAG, as they both require an additional inference per step.

Parameters:

• Use Next Sigma: Enables Self-Guidance
• Shift Scale: Needs to be negative, -30 is recommended in the paper
• Dynamic Shift Scale: Calculate the closest sigma to the timestep described by "timestep + timestep / shift scale"
• Disable Perturbation: Removes the middle block perturbing from PAG (use Self-Guidance only)
