Study Proposes Routing Instead of Fixing to Improve Clinical LLM Answer Selection
A new arXiv paper argues that clinical LLM answers should be selected by routing between decoding strategies rather than by correcting a single model's output. The authors show that the best decoding regime depends on the query, and propose a trajectory-gated router that picks the appropriate method per question. The work aims to improve reliability without adding retrieval, fine-tuning, or external verifier infrastructure that clinical governance would need to approve.
