Least-Loaded Expert Parallelism: Load Balancing An Imbalanced Mixture-of-Experts research paper by Salesforce, 2026

Salesforce · Jan 23, 2026 · Architectures · 5 upvotes 8 months ago

Read on arXiv

What it shows

Imbalanced expert routing in Mixture-of-Experts models leads to computational inefficiencies in expert parallelism, which are addressed by a dynamic rerouting algorithm that balances workload and reduces memory usage.
