Summary

SparseDecoding calibrates on autoregressive activations and adds a sparse matrix-vector kernel.

Natural-text prefill and self-generated decoding can have different activation distributions. Calibrating on generation, excluding prefill, improved the tested pruned models’ long-form results. An optimized N:M kernel delivered up to 1.48 times end-to-end decoding speedup on A100 GPUs across the evaluated model families.

Why it matters
