MoE Training Handbook Ch.2: A Runbook From Hardware Tests to Your First MoE
Nouamanetazi · x · 2026-11-06
The author walks through Chapter 2 of the Ultimate MoE Training Handbook, a practical runbook: test your hardware, build the image, tokenize, train a dense baseline, then a first MoE on one node — kept alongside the dense run so regressions are easy to spot. The handbook's full table of contents covers MoE anatomy (router scoring, routing strategy, load balancing, expert sizing), training stability (optimizer, MTP, upcycling), and serving topics like low-bit experts, expert parallelism, and RL routing — 30k words with 50+ interactive figures.
