FastH3 4-step Preview co.huggingface.hugging-apps/fasth3-4step-preview-demo Check the vendored VSA-H3 kernels against dense attention on this GPU. At `sparsity = 0` the block map is all-true, so VSA-H3 has to reproduce full attention exactly (up to the tile padding and the fp32 pooled selection, which cannot change an all-true mask). That is the one assertion that catches a wrong tile order, a wrong `variable_block_sizes`, or a mis-transposed buffer — all of which would otherwise show up only as a subtly wrong video. Runs on random tensors; no weights are touched. Returns: A markdown report: the dense-equivalence error, and how much of the dense output the 90%-sparse path keeps. | – | Not stated |
