VerNav: Verifier-First Low-Latency Vision-and-Language Navigation

VerNav, a verifier-first framework for low-latency LLM-based VLN, achieves competitive navigation performance among representative LLM-based VLN agents while reducing average decision-stage LLM latency per step by more than $10\times$ compared with autoregressive methods.
