Benchmarking and Error Analysis of Deep Search and Deep Research LLM Agents

The paper introduces a new methodology and analytical framework to diagnose errors in the intermediate execution traces of autonomous Deep Search and Deep Research Large Language Model agents. It presents a taxonomy that classifies these errors into System‑Level and Task‑Level categories, and uses systematic examination of step‑by‑step traces to show how they impact overall performance. The authors also provide empirical experiments and design guidelines aimed at improving the robustness, reasoning, and reliability of these agents.
