Are you a vegan?
But certainly, humans deem sentient and grant certain rights and protections to some other animals (at least in some developed countries). I mentioned it in the other comment[0].
Notably, those animals could not produce output even .1% percent as resembling that of a human as an LM, so clearly that is not the metric—they demonstrate human-like enough behaviour in other ways.

To me, it isn’t. My opinion is irrelevant, though—it seems silly either way: either they take human-like text as proof of human-like sentience, and then ban us being rude to a near-human they are torturing, or they don’t see it as sentient and then what is this ban but a publicity stunt?
