I came up with my estimate of one-to-four orders of magnitude via some quick search results, so, very open to revision. But indeed, the possibility that GPT4.5 is about 10% of the human brain was within the window I was calling a “small fraction”, which maybe is misleading use of language. My main point is that if a human were born with 10% (or less) of the normal amount of brain tissue, we might expect them to have a learning disability which qualitatively impacted the sorts of generalizations they could make.
Of course, comparison of parameter-counts to biological brain sizes is somewhat fraught.
