MindSearch is a multi-agent network search engine framework based on large language models (LLM), with performance akin to Perplexity.ai Pro. Users can easily deploy their own search engines, supporting both proprietary large language models (such as GPT and Claude) and open-source large language models (like InternLM2.5-7b-chat). It features the ability to tackle any real-world problem by utilizing internet knowledge to provide in-depth and comprehensive knowledge base answers; displays detailed solution pathways to improve the credibility and usability of final responses; offers an optimized UI experience with various interface options including React, Gradio, Streamlit, and Terminal; and dynamically constructs graphs that break down user queries into atomic sub-problems within the graph, progressively expanding it based on WebSearcher results.
