Relatedly, I think it's worth noting that Anthropic models have consistently been top-scoring in BullshitBench[0], in a league of their own, really.
Not affiliated with the bench in any way, but I think it surfaces important differences between the behavior of the models from different labs.
TLDR: The benchmark is measuring pushback in response to nonsensical requests and questions, as opposed to going with it and hallucinating a nonsensical answer.
