SpaceX CEO Elon Musk confirmed that Grok Bot weekly usage limits were tightened because serving the agentic AI had become 'unsustainably high' relative to revenue, even as SpaceX's AI division reported strong profits.
Musk recently referred to Grok Bot as having "the fastest growth of a product that I've ever seen in my life."

Over Halloween weekend, some Grok Bot users awoke to something especially spooky: their weekly usage limits were unexpectedly maxed out, even if they hadn’t been using SpaceX’s agentic AI overnight\. Some users reported on X that their[usage](https://x.com/MadnessOfMouth/status/2117028659420606892)jumped from as low as[50% to 100%](https://x.com/GregGaskell/status/2117083536859738409)\.
SpaceX CEO Elon Musk confirmed in an X post on Sunday that this was not a glitch\.
“The cost of serving Grok Bot was unsustainably high relative to revenue,” he[wrote](https://x.com/elonmusk/status/2116992258520064397)in a reply to a question from a user\. He has not addressed the issue on his main feed, but has continued boasting that Grok Bot can help you[buy gifts](https://x.com/elonmusk/status/2116989604104392969)for your family\.

Grok Bot has been positioned as a success story for the newly public SpaceX, which said in a[filing](https://techcrunch.com/2026/10/20/spacexs-ai-business-is-beating-expectations/)last month that AI now makes up 52% of company income\.

Its profit would’ve been[higher](https://techcrunch.com/2026/10/20/spacexs-ai-business-is-beating-expectations/)if not for $1\.2 billion of one\-time costs related to its acquisition of[Cursor](https://techcrunch.com/2026/08/15/spacex-officially-closes-its-cursor-acquisition/)\. Musk recently referred to Grok Bot as having “the[fastest growth](https://www.youtube.com/shorts/Qmc0IN_JuzQ)of a product that I’ve ever seen in my life\.”
Musk has not yet shared how subscribers’ usage limits will be impacted moving forward\.
Paying Grok Bot users saw a week's usage consumed overnight, with Elon Musk citing unsustainably high serving costs while Cursor staff and xAI's status page suggest a possible metering fault affecting multiple subscription plans.
SpaceXAI, Elon Musk's AI unit, is considering an overhaul of its subscription pricing for Grok chatbot and X users, planning a unified subscription with four tiers ranging from a limited free option to a $100/month 'Ultra' tier featuring the Grok Bot AI agent.
A commentary arguing that SpaceX's real challenge is balancing profit from selling tokens for its own Grok Bot versus reselling inference to third-party models like Claude 5.5, in order to fund massive data center buildout while keeping AI pricing accessible.
