I am familiar with the terms, but I also can see how it can be confusing for a lot of people.

Arguably the complaint was more valid for those older GPT models you mentioned.

Ok, the boring way would be a subset of XXS, XS, S, M, L, XL, XXL like clothes sizes. But it loses some marketing appeal and a quirky touch of personality that companies like.

Some models like ViTs use something similar but then introduce words with no unambiguous order, like Small, Medium/Base, Large but then I always forget if Huge or Giant is larger.
