Time to jump ship.
I have noticed 5.3 in xtra high was a turd today. High used to be enough for most of my use cases. xhigh used to surprise me. Now it's incapable of following the very first instructions.
I just hope open source models get as good as last few month's top models before the enshittification has gone too far.
Qwen3.5 (-plus, which isn’t actually open to be fair) is surprisingly decent I’ve found.
