How to Keep Your LLM Chatbots Real - A Metrics Survival Guide
summary
Concrete evaluation recipe: build a synthetic test set from Chroma-embedded docs and run a retriever-augmented-generation stack backed by GPD4.1 and Molly GPT, measure context precision and recall, then evaluate generation with faithfulness vs correctness using both LLM-as-a-judge and modular statement-extraction approaches; use Ragas, Llama Index or DP eval and MLFLow for tooling; aim for ~10–50 questions prototyping, 50–100 for pilots, 100–1000 in production, and >1000 for benchmarking to see meaningful differences.
