One Grok Bot routine on a 5-minute clock wakes up 8,640 times a month.
At Grok 4.6 API rates that's about $400 of compute for one job. Hourly, it's $33. Same bot, same model, same prompt. The only thing that changed is how often it wakes up.
On a subscription you won't see that bill. You'll see your plan's allowance burn 12x faster, mostly on runs where nothing happened.
Everyone setting up Grok Bot is arguing about which bot to hire and how to split the team. Almost nobody is looking at the clock. And the clock is where the bill, the noise and the 3 a.m. failures come from.
This is the full course on routines: how often to run them, when not to schedule at all, how to make a fast routine cheap, what happens when one needs you while you sleep, and a script that tells you which ones to kill.
