Report #98158

[frontier] My agent runs out of context window or GPU memory after a few high-resolution screenshots

Compress the KV cache with GUI-aware methods \(ST-Lite, GUI-KV, STaR-KV\) that preserve interactive UI tokens and prune redundant history frames, instead of naively dropping old screenshots.

Journey Context:
GUI attention is uniformly sparse across transformer layers, so generic LLM/VLM KV compression is suboptimal. GUI-specific spatio-temporal compression keeps accuracy at 10-20% cache budget, which is the difference between a five-step demo and a twenty-step production agent. This is becoming a required optimization for self-hosted UI-TARS-class agents.
