Either this is untrue or my account is in some bugged state. I bought the 300 plan 3.5 weeks ago, and found it's usage about 1/10th of others, running out always the first day of usage for the whole week while CC for example would last 2-3 at higher usage.
It reset just a few hours ago and I've been running it, couldn't be more than 15 sessions none more than an hour long:
---
Session usage: no model calls yet in this session.
Weekly limit: 46%
Next reset: September 27, 23:20
---
I actually have to believe my account is messed up tbh, it's so bad. For reference I've ran 12 fable and some ~40 Opus sessions since reset yesterday on a CC account, at least 5x more usage by my estimate:
Current week (all models)
28% used
Resets Sep 28 at 5am (Pacific/Honolulu)
Ok looking at it more, Grok and Grok Build just really suck. They are about 10x less token efficient, often using 200+ tool calls in a row for what are not even big tasks where Opus would use 5-10. Their cache hit rate is worse, and two sessions got into basically unnecessary loops costing a solid quarter of the entire week. And this was on smaller tasks as I tend to use it for easier things.
One possible reason is that Grok Bot consumes more quota because it uses their infra instead of your computer.
I can't help much more than that, I did that research in the last few days, but I never used Grok myself.
I pay for GPT, Claude and Gemini. Last week I consumed all my quota on two of them, so I wondered which next subscription I would pay for if needed.
I just used Build for ~4 hours, no Bot.
