As an experiment, I set it up with a z.ai $3/month subscription and told it to do a tedious technical task. I said to stay busy and that I expect no more than 30 minutes of inactivity, ever.

The task is to decompile Wave Race 64 and integrate with libultraship and eventually produce a runnable native port of the game. (Same approach as the Zelda OoT port Ship of Harkinian).

It set up a timer ever 30 minutes to check in on itself and see if it gave up. It reviews progress every 4 hours and revisits prioritization. I hadn't checked on it in days and when I looked today it was still going, a few functions at a time.

It set up those times itself and creates new ones as needed.

It's not any one particular thing that is novel, but it's just more independent because of all the little bits.
