ReasonBENCH: Benchmarking the (In)Stability of LLM Reasoning

Researchers introduce ReasonBENCH, a comprehensive benchmark revealing that LLM reasoning systems exhibit significant performance variance across repeated executions, with the best-performing strategy winning only 77% of head-to-head comparisons. The study demonstrates that this instability is structured rather than random, challenging the validity of single-run benchmark scores as reliable indicators of model quality.

Is Escalation Worth It? A Decision-Theoretic Characterization of LLM Cascades

Researchers develop a decision-theoretic framework for optimizing LLM cascades, where cheaper models defer to expensive ones on low-confidence queries. Testing across five benchmarks reveals that cascade performance is fundamentally limited by structural costs rather than routing sophistication, with simpler router-based approaches often outperforming optimized cascade policies.
