Author here: My first version ran alongside my Claude Code subscription, and pretty much banged through my entire weekly subscription in a couple of days. So I bought a GLM subscription and ate through that at the same pace (even though I only used it for the agent).

I've done a bunch of optimizing of the agent since then, like not running in peak times and throttling. But without controls and optimization, the agent will chew through all the tokens you can throw at it.

Put another way: people who say they have agents coding 24/7 are on higher budgets than me.
