Huh, I was wondering what the size of the non-davinci models were; guess that make sense.
It's still telling that a "small" GPT-3 model can risk cannibalizing a larger model.
Ada is 2.7B, Babbage is 6.7B, Curie is 13.0B, and DaVinci is 175B. The new one they announced last month is in the 20-50B range I think, not totally sure though.
