I was getting semi-useful results from a 128GB M4 Max. That was a few months ago, and the models have improved (quite a bit) since then, but now I'm happy to send my $20/month to get Claude code.

It's still frustrating as hell to come down in the morning, having given it a list of tasks to do overnight, with tests to pass before they're "done" and find that it worked for about 20 minutes after I went to bed, and decided that it would stop at "3am" (it wasn't) and "not do significant work this at this late hour". Like WTF ? You're an LLM. You don't sleep.

Bloody training data full of humans demanding sleep. I tells ya...
