ComfyUI-TCD-scheduler

ComfyUI Custom Sampler nodes that implement Zheng et al.'s Trajectory Consistency Distillation based on https://mhh0318.github.io/tcd

This custom node repository adds TCDScheduler and SamplerTCD nodes to the Custom Sampler category.

Just clone it into your custom_nodes folder and you can start using it as soon as you restart ComfyUI.

LCMScheduler has one special parameter:

• gamma, a parameter used to control the stochasticity in every step. When gamma = 0, it represents deterministic sampling, whereas gamma = 1 indicates full stochastic sampling.

  The default value is 0.3, but it is recommend using a higher value when increasing the number of inference steps.
