Your LLM passed the demo. It failed production. Here's how to fix that. Most teams ship RAG pipelines with zero evaluation ā 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 ā using the open-source RAGAs framework. š„ What you'll learn: 00:00 ā Why "it looks right" isn't LLM testing 00:25 ā The 3 pillars of RAG evaluation 01:15 ā RAGAs framework: 4 automated metrics explained 02:45 ā The Architect's full LLM testing stack (RAGAs + DeepEval + LLM-as-Judge) 03:45 ā Your 3-step action plan for this week 04:20 ā Stop being a user. Become an architect. š 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 š Resources: ⢠RAGAs GitHub: https://github.com/explodinggradients/ragas ⢠DeepEval: https://github.com/confident-ai/deepeval š” Who this is for: AI engineers, ML engineers, data scientists, and developers building RAG applications who need systematic evaluation instead of manual testing. šļø Stop being a user.
