Over the Halloween weekend, some Grok Bot users found their weekly usage quotas suddenly exhausted (some jumped directly from 50% to 100%), and according to The Daily Telegraph, some users had their quotas cut in half. SpaceX CEO Elon Musk 11 1 wrote in a reply to users on X: "The cost of serving Grok Bot is unsustainably high relative to revenue," leading TechCrunch to conclude this is not a bug. Grok Bot is an agentic product from SpaceX's AI division that can browse the web, reply to emails, and log into accounts to perform tasks; according to The Decoder, it shares a single quota with Grok and Cursor. Musk did not specify how quotas will be calculated going forward.
Confidence: High (100) · Event time 2026-11-01
Reasoning
- This is the third major vendor in a week to tighten "flat-rate" usage limits: OpenAI 12 started sharing token quotas between ChatGPT and Codex and restricting multiple accounts, while Anthropic also stated that the cost of agentic tasks is 4 to 15 times that of standard chat (according to The Decoder). Agents capable of performing long-duration autonomous work are pushing flat-rate subscriptions toward usage-based billing.
- According to TechCrunch, Grok Bot was described by Musk less than two weeks ago as "the fastest-growing product he has ever seen"; SpaceX's filings last month stated that AI already accounts for 52% of the company's revenue. Fast growth coupled with even faster costs is a common issue for agentic products at this stage.
Usage
- Grok Bot / Cursor subscribers: Monitor weekly quota displays; consider splitting heavy tasks or switching to usage-based APIs; official rules have not yet been announced.
Risks
- The specific extent of quota adjustments and whether all subscription tiers are affected have not been formally announced by xAI / SpaceX, relying only on a single reply from Musk and user feedback; the editor did not directly open the original X post, and the quote comes from a post embedded by TechCrunch.
- The "quota cut in half" claim comes from The Daily Telegraph's reporting on some users and has not been officially confirmed.
