ComfyUI node implementing caching optimizations for Chroma
Inspired by techniques like TeaCache and FBCache. Unlike other models, Chroma's first block residual has low similarity between timesteps, so we refresh the cache at fixed intervals instead.
Use the Chroma Cache node.
Reasonable settings:
- start: 0.30
- end: 1.0
- caching interval: 2-4
