ComfyUI-Sampler-Adaptive

Adaptive sampling custom node for ComfyUI.

See anima_00265_.png for an example workflow.

Known Limitations

• Ancestral samplers (e.g., euler_ancestral, dpmpp_2s_ancestral) do not work correctly at this time.
• Samplers from RES4LYF are not supported.
• Multistep/stateful samplers (e.g., dpmpp_2m, lms, ipndm, dpmpp_2m_sde) are not supported. They will produce output equivalent to first-order samplers. Use euler, heun, dpm_2, or other stateless samplers instead.

Parameters

• error_type: Cosine or MSE similarity for error calculation between steps
• base_step_size: Base multiplier for step size adaptation
• min_step_size: Minimum allowed step size
• max_step_size: Maximum allowed step size
• max_steps: Maximum number of adaptive steps
• smoothing_coef: Smoothing coefficient for step size updates (0.0 = no smoothing, 1.0 = full smoothing)
