What is a multi-source autonomous research agent?

It's an AI system that queries multiple sources (Wikipedia, GitHub, Reddit, etc.) in parallel, self-evaluates coverage, and iterates if needed—built with LangGraph for stateful workflows.

How do you build a research agent with LangGraph and Ollama?

Use StateGraph for nodes like plan_research, parallel_search (via ThreadPoolExecutor), and evaluate. Swap LLMs via env vars; run local with Ollama for zero cost.

Can this research agent run locally on my machine?

Absolutely—defaults to Ollama on localhost:11434. Handles 10+ sources in ~45s on decent hardware; no API keys required.
