# Modern Information Retrieval Evaluation In The RAG Era

> Free video lecture on modern IR benchmarks and evaluation for RAG pipelines.

This free 45-minute Maven Lightning Lesson explains why traditional IR benchmarks like BEIR fail to reflect real-world RAG demands. Led by Nandan Thakur, Hamel Husain, and Shreya Shankar, the session introduces FreshStack, an evaluation benchmark built from recent StackOverflow and GitHub content.
