Zero-shot Vision-and-Language Navigation in Continuous Environments (VLN-CE) requires agents to follow natural language instructions and navigate without task-specific training. Prior works have demonstrated the potential of open-source large language models (LLMs) in zero-shot VLN-CE, yet two major…
