Report #57688

[frontier] Agent wastes tokens and hits rate limits processing full 1080p screenshots for tasks requiring only a small region

Implement 'foveated vision': use a lightweight region-proposal model \(OmniParser v2 or YOLOv8 fine-tuned on UI elements\) to detect Regions of Interest \(ROIs\) in the full screenshot at low resolution. Crop to these ROIs plus 100px context padding at full resolution before sending to the multimodal LLM. Maintain a 'peripheral' low-res thumbnail \(256px wide\) for global context only when needed.

Journey Context:
Full HD screenshots consume 1500-3000 tokens each. For 20-step tasks, this exceeds context limits. Early Computer Use implementations sent full screens. The biological solution is foveation: high-resolution only at the point of attention. OmniParser v2 provides the region proposal network \(RPN\) for UI elements specifically. The 100px padding ensures the model sees context \(nearby text labels\). The peripheral thumbnail prevents 'lost in space' errors when the ROI is ambiguous. This reduces tokens by 70-80% without accuracy loss.
