Report #51293
[frontier] Vision encoders waste capacity on non-functional visual elements \(gradients, shadows\) while missing subtle UI state indicators \(1px borders, opacity changes indicating disabled state\)
Preprocess screenshots with 'UI Chrome Stripping': use edge detection and color clustering to identify functional regions, or use accessibility metadata to generate attention masks that suppress non-interactive regions before vision encoding, or alternatively render 'semantic screenshots' \(DOM-based simplified representations\)
Journey Context:
Raw screenshots contain ~90% non-semantic pixels for agent tasks. Current vision transformers treat all pixels equally, leading to missed subtle state cues \(e.g., 'is this checkbox checked' depends on 2-3px checkmark\). DOM-based approaches miss visual state, screenshot approaches miss semantic efficiency. Emerging pattern: 'Semantic screenshot' generation using browser DevTools Protocol to capture computed styles and simplified geometry, reducing vision tokens by 80% while preserving functional layout.
