Hugging Face Releases HOPE, a Second-Order MoE Expert Pruning Method
Understand the story
On November 9, 2026, Hugging Face published HOPE (Higher-Order Pruning of Experts) on its official blog (first-hand source), a second-order expert pruning method for MoE models. Unlike traditional first-order pruning methods, which score each expert independently, HOPE incorporates pairwise interactions between experts into pruning decisions—meaning that when making pruning judgments, it considers the 'partner' relationships between experts, thereby preserving important expert combinations when trimming experts. This is the first report on this event; so far there is only news of the method's introduction, with no follow-up reports yet on further experimental results or practical performance.
