Report #47484

[frontier] Why does my agent fail to read small text but also miss UI layout when I increase resolution?

Implement dynamic resolution switching: use low-res \(e.g., 768px\) for UI element detection and spatial reasoning, switch to high-res \(e.g., 2k\) only for OCR-critical steps, with explicit 'zoom' actions.

Journey Context:
VLMs have conflicting optimal inputs: high resolution needed for OCR but hurts UI element detection because the model gets distracted by fine details and loses layout context. Standard practice sends one screenshot size, causing either OCR failures \(too blurry\) or layout hallucinations \(too cluttered\). The frontier pattern treats resolution as an action: the agent explicitly 'zooms in' \(high-res crop\) for reading and 'zooms out' \(low-res full screen\) for navigation. This mimics human visual attention, reduces token costs \(avoiding 4k images for simple navigation\), and prevents the 'screenshot compression paradox' where choosing one resolution guarantees failure on either text or layout.
