Report #94144

[frontier] Computer-use agents fail on long-horizon tasks because they either consume entire context windows with high-res screenshots or lose detail with aggressive compression; no strategy exists for 'visual working memory' vs 'visual long-term memory'

Implement pyramidal visual encoding: full-resolution for current viewport, thumbnail summaries \(25% scale\) for historical states, and text descriptions \(VLM-generated\) for archival context; use explicit 'visual recall' mechanisms to promote thumbnails back to full-res when referenced

Journey Context:
Current approaches treat all historical screenshots equally, either keeping everything full-res \(hitting token limits after 3-4 steps\) or compressing everything equally \(losing critical details\). This mirrors the human visual system's separation between foveal \(high-res\) and peripheral \(low-res\) vision, plus our ability to recall detailed mental images from summaries. The pattern requires explicit memory management: current state = full res \(1024x768\), recent history \(last 3 steps\) = medium res \(512x384\), old history = caption only \('page showing login form'\). When the agent asks 'what was on the previous page?', the system must 'recall' by re-injecting the thumbnail or re-capturing if needed. This is essential for 50\+ step computer use tasks.
