Open Deep Research — агент глубокого исследования

★ 12.6K

Open Deep Research is LangChain's open-source deep-research agent: given a topic, it plans the investigation, searches the web for sources, reads them, and assembles a coherent report grounded in what it found. Reach for it as a self-hosted alternative to "Deep Research": run a multi-step investigation of a question, gather and cross-check sources, and get a structured result instead of manual googling and stitching. It is built on the LangChain/LangGraph ecosystem, works with various LLMs and search tools on your own keys, and is configurable for depth and sources. Its focus is a configurable research agent for "question → search → report," not a finished chatbot or a search engine itself: it is a framework you deploy and tune. In job it sits alongside deer-flow, with the difference being direct integration with the LangChain ecosystem and an emphasis on a transparent, configurable pipeline.
