Report #35690

[frontier] Feeding raw screenshots \(hundreds of thousands of tokens\) into every step of an agent loop is prohibitively expensive and quickly exhausts context windows

Use 'late interaction' vision architectures \(e.g., ColPali-style\) that embed screenshots into compact visual token representations locally, then perform late cross-attention with text queries only when needed, rather than passing raw pixels to the LLM.

Journey Context:
Standard practice is either: 1\) Send full image to GPT-4V \(expensive, limited context\), 2\) Use small descriptive captions \(lossy, misses layout\). ColPali demonstrated that document understanding \(and by extension GUI understanding\) can use Vision Transformers to create token-level embeddings that are later 'interacted' with text queries using MaxSim operators. For agents, this means the 'memory' of what a screen looked like can be stored as compact embeddings \(hundreds of tokens equivalent, not thousands\), and retrieved/queried efficiently. This is crucial for long-horizon computer-use agents where keeping 10 screenshots in raw form would exceed context limits.
