The hallucination benchmark is hallucinating
I've been very curious about that too. I wonder if it's actually much better at admitting when it doesn't know something, because it thinks it's a "dumber model". But I haven't played with this at all myself.
Hallucination benchmarks accept "I don't know", which Haiku did at least a little. Here are other benchmarks corroborating: https://suprmind.ai/hub/ai-hallucination-rates-and-benchmark...
