ComfyUI-Spectrum-Anima

Spectrum acceleration for native ComfyUI Anima checkpoints.

Spectrum forecasts Anima's hidden transformer features and skips selected transformer forwards. No additional dependencies are required.

Install

Copy or clone this folder into:

cd ComfyUI/custom_nodes
git clone https://github.com/Nif00/ComfyUI-Spectrum-Anima.git

Restart ComfyUI after installation.

Usage

Add Spectrum Apply Anima between the Anima model loader and the sampler:

Anima Loader → Spectrum Apply Anima → CFGGuider → KSampler

For conservative acceleration, use:

window_size: 2
flex_window: 0
warmup_steps: 5
tail_actual_steps: 3

Set window_size to 1 to disable skipping. Enable debug to log actual and forecasted step counts.

Samplers

Supports er_sde, Euler, LCM, DDPM, DPM++ 2M, and DPM++ 2M/3M SDE variants. Unsupported multi-evaluation samplers fall back to native Anima inference.
