+## WebThinker: Empowering Large Reasoning Models with Deep Research Capability
+
+Large reasoning models (LRMs), such as OpenAI-o1 and DeepSeek-R1, demonstrate
+impressive long-horizon reasoning capabilities. However, their reliance on
+static internal knowledge limits their performance on complex,
+knowledge-intensive tasks and hinders their ability to produce comprehensive
+research reports requiring synthesis of diverse web information. To address
+this, we propose WebThinker, a deep research agent that empowers LRMs
+to autonomously search the web, navigate web pages, and draft research reports
+during the reasoning process. WebThinker integrates a Deep Web
+Explorer module, enabling LRMs to dynamically search, navigate, and extract
+information from the web when encountering knowledge gaps. It also employs an
+Autonomous Think-Search-and-Draft strategy, allowing the model to
+seamlessly interleave reasoning, information gathering, and report writing in
+real time. To further enhance research tool utilization, we introduce an
+RL-based training strategy via iterative online Direct Preference
+Optimization (DPO). Extensive experiments on complex reasoning benchmarks
+(GPQA, GAIA, WebWalkerQA, HLE) and scientific report generation tasks (Glaive)
+demonstrate that WebThinker significantly outperforms existing methods and
+strong proprietary systems. Our approach enhances LRM reliability and
+applicability in complex scenarios, paving the way for more capable and
+versatile deep research systems.
