ComfyUI-INT4-Fast enables efficient 4-bit model inference on consumer GPUs

By PulseAugur Editorial · [1 sources] ·

A new custom node package called ComfyUI-INT4-Fast has been developed to enable ultra-fast, memory-efficient INT4 (W4A4) model inference within ComfyUI. This package leverages GPU Tensor Cores for running 4-bit weights and activations, and features native mixed-precision checkpoint support. Testing on an RTX 3060 with 6GB VRAM demonstrated impressive performance, achieving 1.78 seconds per iteration for a 1024x1024 resolution image. AI

IMPACT Enables faster and more memory-efficient AI model generation on consumer hardware.
