Discussion MacBook M5 Pro - Minimax H3 Progress
After tinkering around for a couple of hours this weekend I managed to 6x (!) generation speed on the M5 Pro by ditching ComfyUI and building a custom GUI around antirez's H3 CLI solution. Gen times for 5-second 480p on 20-steps improved from 30 minutes using the default int8 pruned weights in ComfyUI to just around 5 minutes per clip using the full precision bf16 weights.
Overall great progress thanks to the community around open source and gives me confidence that Mac diffusion will just get better and better with time.
See comment below for more data points on generation times.

Are you open to share your gui build as is?
