“ Models don’t get old as fast as they used to”

^^^ I think the opposite is true

Anthropic and OpenAI are releasing new versions every 60-90 days it seems now, and you could argue they’re going to start releasing even faster

Are they becoming better at the same rate as before though?

Per release, I’d say no.

Per period of time, I’d say yes.

In my unscientific experience, yes, but being better at a certain rate is hard to really quantify, unless you just pull some random benchmark numbers.

No.

yes, pretty much
