Your LLM is Lying to You — Here's How to Test It (RAGAs Framework)

Description

Your LLM passed the demo. It failed production. Here's how to fix that. Most teams ship RAG pipelines with zero evaluation — no metrics, no baselines, just vibes. In this video, I break down the 4 core metrics every AI engineer needs to evaluate their LLM: Faithfulness, Answer Relevancy, Context Precision, and Context Recall — using the open-source RAGAs framework. 🔥 What you'll learn: 00:00 — Why "it looks right" isn't LLM testing 00:25 — The 3 pillars of RAG evaluation 01:15 — RAGAs framework: 4 automated metrics explained 02:45 — The Architect's full LLM testing stack (RAGAs + DeepEval + LLM-as-Judge) 03:45 — Your 3-step action plan for this week 04:20 — Stop being a user. Become an architect. 📌 Key topics covered: • LLM evaluation and testing frameworks • RAGAs (Retrieval Augmented Generation Assessment) • Hallucination detection and faithfulness scoring • Context precision and recall for RAG pipelines • DeepEval, LangSmith, and LLM-as-Judge patterns • Production-grade AI quality assurance 🔗 Resources: • RAGAs GitHub: https://github.com/explodinggradients/ragas • DeepEval: https://github.com/confident-ai/deepeval 💡 Who this is for: AI engineers, ML engineers, data scientists, and developers building RAG applications who need systematic evaluation instead of manual testing. 🏗️ Stop being a user.
