V3 Sampler Options

Samplers

• k-euler
• k_euler_ancestral
• k_dpmpp_2s_ancestral
• k_dpmpp_2m
• k_dpmpp_sde
• ddim_v3

Notes

• The "noise_schedule" is automatically set to "exponential" for k_dpmpp_2m. For other samplers, it defaults to "noise_schedule": "native".

Limitations under ddim_v3 Sampler

• The following features are not supported:
  • "noise_schedule": "native" (This option should be removed)
  • "sm": false
  • "sm_dyn": false (These two options should be set to false)

New Options

• "sm": bool (Needs to be enabled for the next option)
• "sm_dyn": bool (Can be used only when "sm" is true)
• "dynamic_thresholding": bool
