Report #76938

[frontier] Standard VLMs downsample high-res screenshots \(1920x1080\) to 224x224, losing fine-grained text and small button details

Use high-resolution encoding with cross-module attention \(CogAgent\) - a high-res visual encoder maintains detail while interacting with LLM via cross-attention, without overwhelming context length

Journey Context:
Standard vision encoders \(CLIP, SigLIP\) use low resolution. For GUI agents, reading small text or distinguishing icons requires high-res. CogAgent uses a separate high-res encoder that 'cross-attends' to the LLM, avoiding feeding massive image tokens directly into the LLM context. This balances detail and efficiency.
