Mixture of Experts (MoEs) in Transformers
MoEs just became the efficiency standard. Here's why every foundation model lab is adopting them.
Why it matters
Mixture of Experts architectures represent a fundamental shift in how models scale compute and parameters. Understanding MoE trade-offs is now table-stakes for any org building or deploying foundation models competitively.
