bitsandbytes2 dynamic runtime compression: per-layer bit allocation plus runtime expert swaps
Tim_Dettmers · x · 2026-09-22
Dettmers summarizes the bitsandbytes2 dynamic runtime compression framework: it allocates different quantization bit levels and expert removal levels per layer to increase compression while keeping quality high, and exchanges experts dynamically at runtime via Dynamic REAP for better quality and out-of-context generalization.
