That's odd to me. I have SuperGrok with X Premium+. I use the crap out of Grok in my daily life, including to build a couple self-hosted apps as an amateur. I have a Grok bot monitor my email every 15 minutes and file things away for me. I have another bot that monitors for blood test results through Goodlabs. And I'm talking to it all the time on my 2 hour round-trip commute . . . and I never even get close to using my quota.
