Search-Time Contamination in Deep Research Agents: Measuring Performance Inflation in Public Benchmark Evaluation 事件

Search-Time Contamination in Deep Research Agents: Measuring Performance Inflation in Public Benchmark Evaluation arXiv:2606.05241v1 Announce Type: cross Abstract: Public benchmarks enable fair and reproducible evaluation of LLM reasoning, but they become fragile for deep research agents that actively search the web during inference. Such agents may retrieve public benchmark metadata, question context, or even ground-truth answers via web search. This gives rise to Search-Time Contamination (ST
