Excited to share open-rag-eval (https://github.com/vectara/open-rag-eval) a new open source project to help scale RAG evaluation. The key benefit: it does not require golden answers so much more scalable.
Would love any thoughts or feedback (or even better - if you want to contribute a PR that would be great).

I'm excited to share our updated hallucination evaluation model (called HHEM-2.1-Open) as well as the updated leaderboard that ranks LLM by the propensity to hallucinate.

Any specific topics you can suggest?
Perhaps politics it too sensitive, maybe we can focus on other topics that are common in debate tournaments?

If you are a debate fan or did this as an extracurricular activity as a kid, you might have fun with this demo - debate bot. Debate against AI/RAG:
