Open Deep Research

Описание: AI assistants capable of in-depth, autonomous ("deep") research on user-supplied topics has become a major area of interest. Here, we discus a few of the common architectures across various closed / open deep research tools and provide an overview of our implementation. We show how to run it locally using LangGraph studio. We also review many of the configurations, allowing users to customize the input, the models, the search API, the report structure, and the depth of research.
