presumably whatever the top model uses and then some, since the human can use the model.

I wonder if a model could score higher if it had a human at its disposal?

With a human at its disposal, it could probably count the number of R's in strawberry!

In all seriousness though, adding capabilities should not normally reduce the effectiveness of a model (within reason: don't pollute the context window with millions of useless tools).

Maybe models should ask for human-in-the-loop input, as a matter of convention.
