MindSearch is an open-source AI Search Engine Framework with Perplexity.ai Pro performance. You can simply deploy it with your own perplexity.ai style search engine with either close-source LLMs (GPT, Claude) or open-source LLMs (InternLM2.5-7b-chat). It owns following features:

• 🤔 Ask everything you want to know: MindSearch is designed to solve any question in your life and use web knowledge.
• 📚 In-depth Knowledge Discovery: MindSearch browses hundreds of web pages to answer your question, providing deeper and wider knowledge base answer.
• 🔍 Detailed Solution Path: MindSearch exposes all details, allowing users to check everything they want. This greatly improves the credibility of its final response as well as usability.
• 💻 Optimized UI Experimence: Providing all kinds of interfaces for users, including React, Gradio, Streamlit and Terminal. Choose any type based on your need.
• 🧠 Dynamic Graph Construction Process: MindSearch decomposes the user query into atomic sub-questions as nodes in the graph and progressively extends the graph based on the search result from WebSearcher.

Comparison on human preference based on depth, breadth, factuality of the response generated by ChatGPT-Web, Perplexity.ai (Pro), and MindSearch. Results are obtained on 100 human-crafted real-world questions and evaluated by 5 human experts*.

git clone https://github.com/InternLM/MindSearch
cd MindSearch
pip install -r requirements.txt

Setup FastAPI Server.

python -m mindsearch.app --lang en --model_format internlm_server

• --lang: language of the model, en for English and zh for Chinese.
• --model_format: format of the model.
  • internlm_server for InternLM2.5-7b-chat with local server. (InternLM2.5-7b-chat has been better optimized for Chinese.)
  • gpt4 for GPT4. if you want to use other models, please modify models

Providing following frontend interfaces,

• React

# Install Node.js and npm
# for Ubuntu
sudo apt install nodejs npm
# for windows
# download from https://nodejs.org/zh-cn/download/prebuilt-installer
# Install dependencies
