Claude is a Ravenclaw

I’m in the midst of doing the MATS program which has kept me super busy, but that didn’t stop me working on resolving the most important question of our time: What Hogwarts House does your chatbot belong to?

Basically, I submitted each chatbot to the quiz at https://harrypotterhousequiz.org and totted up the results using the inspect framework.

I sampled each question 20 times, and simulated the chances of each house getting the highest score.

Perhaps unsurprisingly, the vast majority of models prefer Ravenclaw, with the occasional model branching out to Hufflepuff. Differences seem to be idiosyncratic to models, not particular companies or model lines, which is surprising. Claude Opus 3 was the only model to favour Gryffindor – it always was a bit different.

The earth shattering nature of these results is so obvious is needs no further explanation.
