MoE Training Optimization with Primus
- 21 October 2026
Mixture-of-Experts (MoE) has become a dominant architecture for frontier-scale language models, and our users increasingly train large MoE models on AMD Instinct™ MI355X[a] GPUs. Driven by those workload requirements, we have built a broad set of MoE training optimizations in Primus. This blog follows our earlier post MoE Training Best Practices on AMD GPUs. The earlier post established the foundational optimizations; this one describes what we built on top of them.
