  "summary": "Comprehensive reference on Sparse/MoE transformer architectures covering key models (Mixtral, DeepSeek-V3, DBRX, Switch Transformer), efficiency gains (2-18x parameter efficiency ratios), and safety implications; concludes that MoE introduces routing complexity that creates interpretability gaps but existing safety evaluation approaches largely transfer, with expert-level analysis and routing characterization as key open research gaps.",
  "description": "Analysis of Mixture-of-Experts and sparse transformer architectures where only a subset of parameters activates per token. Covers Mixtral, Switch Transformer, and rumored GPT-4 architecture.",
