A new implementation of the MiniMax H3 FirstBlockCache has been released for ComfyUI, offering significant speed improvements for image generation. Tested on an RTX 5090, the cache reduces generation time by 30-33%, achieving up to a 1.49x speedup. This lightweight, dependency-free node is inspired by cross-step caching research and does not require additional Python packages or custom kernels. AI
IMPACT Accelerates image generation workflows for users of ComfyUI and compatible hardware.
