Vision-Language Models Show Fragile Path Following Capabilities

By PulseAugur Editorial · [1 sources] ·

A new research paper published on arXiv highlights significant weaknesses in current vision-language models (VLMs) regarding their ability to follow continuous visual paths. The study found that even under controlled conditions, VLMs struggle to maintain a stable path, particularly when other nearby paths are present. This fragility appears to stem from the visual encoding stage, where information for path continuation weakens. Attempts to improve performance through model scaling, additional reasoning, or explicit tracing instructions yielded limited success, suggesting a fundamental lack of robust path-following mechanisms in existing VLMs. AI

IMPACT Reveals fundamental limitations in VLM path-following, potentially impacting applications requiring visual navigation and scene understanding.

    VLMs Trace Without Tracking: Diagnosing Failures in Visual Path Following

    arXiv:2605.15672v2 Announce Type: replace-cross Abstract: Vision-language models (VLMs) perform strongly on multimodal benchmarks, yet their ability to reliably follow continuous visual structure remains unclear. We focus on path following, a basic operation that requires followi…
