Building a multi-source autonomous research agent with LangGraph, ThreadPoolExecutor and Ollama

This research agent project is an impressive demonstration of leveraging large language models (LLMs) and parallel processing techniques for efficient information synthesis. Here's a summary of key aspects:

1. Architecture Overview:

   • Uses LangChain and Streamlit to create an interactive web application.
   • Employs threading and asynchronous calls to run multiple data retrieval tasks in parallel.

2. Parallel Processing:

   • The core idea is to fetch information from various sources (GitHub, Stack Overflow, Reddit, etc.) simultaneously rather than sequentially.
   • This significantly reduces the overall time required for research by minimizing wait times between API calls.

3. LLM Integration:

   • Supports both local and cloud-based LLMs via environment variables.
   • Uses Ollama or OpenAI APIs depending on configuration.
   • Provides a seamless switch between different models (e.g., Groq, Gemini) without changing the codebase.

4. Agent Design:

   • Defines agents for each data source with specific retrieval and summarization logic.
   • Agents are designed to be modular and can be easily extended or modified.

5. Threading Challenges:

   • Initially faced issues with nonlocal variables in threaded callbacks, which
