Sharding Prevents LLM Oversight Failures and Adversarial Exploitation
New research shows that LLM judges degrade in accuracy as the number of verdicts per call increases, even when given equivalent compute budgets — a form of oversight failure with real implications for automated evaluation pipelines. The proposed fix, 'sharding', partitions requirements into smaller groups handled by separate calls and aggregates results, improving expert agreement across research replication, legal, and clinical benchmarks. This is directly relevant to anyone using LLM-as-judge setups for evals or RLHF reward modeling at scale.

EntropyMoE: Entropy-Aware Sparse Expert Routing for Tokenizer-Free LLMs
EntropyMoE introduces a Mixture-of-Experts architecture specifically designed for byte-level, tokenizer-free LLMs that use dynamic patch grouping. Rather than applying uniform dense feed-forward computation to every patch, the router uses entropy signals to selectively activate experts, with each patch's byte coverage factored into workload accounting. This addresses a known efficiency gap in byte-patch models and could improve their competitiveness with tokenizer-based architectures on variable-granularity inputs.
