ComfyUI-TeaCache integrates the TeaCache caching approach into ComfyUI, enabling 1.5x-2x speedups during diffusion model inference without significant quality loss. It estimates and leverages fluctuating differences in model outputs across denoising timesteps to skip redundant computations. The tool supports multiple diffusion model architectures including FLUX-Kontext, HiDream-I1 variants, and Lumina-Image-2.0, with LoRA support for these models.
