The $0 LLM Upgrade: Make Your Local Model LIVE with Real-Time RAG | LangChain for Beginners (Part 4) #dougortiz Welcome to Part 4 of our LangChain for Beginners series! 🤯 Stop settling for stale data! Did you know the local LLM you're running (like TinyLlama) is totally unaware of what happened yesterday? That's the biggest bottleneck in building real-world AI applications. In this video, we tackle the ultimate LLM challenge: live, real-time data. I'll show you how to supercharge your local, zero-cost LLM with a web search capability using LangChain and the DuckDuckGo wrapper. The best part? NO API KEYS REQUIRED. NO COST TO YOU. You can run this entire Retrieval Augmented Generation (RAG) system on a FREE Google Colab instance. This is the power of RAG with live data, and it’s the future of building truly intelligent AI agents. Learn the setup, the code, and how to instantly ask your local LLM questions about current events (like who won the 2024 Eurovision Song Contest!). Key Takeaways in this Part 4 Tutorial: ✅How to combine Hugging Face models with LangChain. ✅Integrating the DuckDuckGo wrapper for zero-cost web search. ✅Building a real-time RAG pipeline from scratch. ✅Running it all on a FREE Google Colab CPU/GPU.
