Report #61100

[frontier] Vision-based agents hallucinate UI element locations when using raw coordinates or vague descriptions

Overlay numbered markers \(Set-of-Mark\) on UI elements and reference elements by ID rather than coordinates or descriptions

Journey Context:
Raw coordinates fail across resolutions; semantic descriptions are ambiguous; SoM provides deterministic visual grounding that survives layout shifts
