 ## Evaluation
 
-* Motivation
-* Evaluation tool
-    - Ragas
-    - Deep Eval
-* Statistical significance

+
+## Why Evaluate an LLM System?
+
+* Measure performance
+* Ensure good user experience
+* Detect bias & harm
+* Comply with ethical & legal standards
+
+---
+
+## Benefits of Evaluation
+
+* Improvement:
+  - Pinpoints weaknesses (e.g., hallucinations)
+  - Enables data-driven model tuning
+
+* Benchmarking:
+  - Compare models (GPT, Gemini, Granite, etc.)
+  - Ensures reliability over time

+
+### Lightspeed Evaluation Framework
+
+* Multi-Framework LLM as a Judge
+  - Ragas, DeepEval and custom implementations
+* Turn & Conversation-Level
+  - Individual queries and multi-turn conversations
+* Tools/Agents Support
+* LLM Providers
+  - OpenAI, Watsonx, Gemini, vLLM and others
+* Setup/Cleanup Scripts
+* Statistical Analysis
