I agree with what you say here, but I still don’t feel like this gives Marcus the edge here, because Perplexity does a fantastic job at finding correct information and, in my experience, never hallucinates. I would call Perplexity and whatever they’re doing a pretty “robust” solution to hallucination.

So there are solutions to hallucination, but the product has to prioritize that to the extent that it reduces the model’s effectiveness as a general tool.
