Report #64719

[frontier] Long-horizon agents exceed context window because high-resolution screenshots consume 1500\+ tokens each

Implement hierarchical visual compression: use high-resolution \(e.g., 1568px\) only for current active viewport; downgrade historical screenshots to low-resolution \(e.g., 768px\) or textual descriptions after each step; explicitly promote regions to high-res before interaction

Journey Context:
Naive agents keep full-resolution history, burning 100k\+ tokens per trajectory. Simple truncation loses critical visual context. Pattern emerging from production agents: treat visual context like CPU cache - L1 \(current view, high-res\), L2 \(recent views, low-res\), L3 \(text summaries\). Requires explicit resolution management in API calls \(OpenAI/Anthropic support low/high res modes\).
