A MEMIT-style knowledge editing framework for MoE LLMs that formulates per-expert updates via tensor structure and applies Woodbury identity for low-rank inversions, achieving up to 6x speedup with comparable editing quality.
We perform 1000 edits with batch size 50 and measure routing similarity (RS) on both editing set and preserved 1000 edits set, averaging score over windows of 10 layers
