LLM routing hypothesis confirmed in code security vulnerability detection

By PulseAugur Editorial · [2 sources] ·

A new research paper explores the 'router hypothesis' in large language models (LLMs), suggesting that models possess knowledge but struggle with internal routing to activate it. The study reproduced prior findings from mathematical reasoning tasks in code security vulnerability detection, using models like GPT-OSS-120B, Llama-3.3-70B, and Gemma-4-31B. Results showed that structural priors (cheatsheets) dramatically improved performance on synthetic data but led to a significant drop in accuracy when applied to real-world CVE data, indicating a cross-domain trade-off. AI

IMPACT Suggests distribution-aware training may be more effective than prompt calibration for improving LLM reliability on real-world data.
