Someone applied Jev for attention sparsification in MiniMax H3 video generation, cutting generation time from 06:07 to 03:34 — over 40% faster. Author's GitHub repo: https://github.com/sepiablue-ai/ComfyUI-MiniMax-H3-W4A4-VSA/tree/exp/jev-adaptive-vsa
Since there are now many open-source alternatives to Jev, further optimizations are expected soon. The poster asks if anyone has tried the repo.
