SpaceX has reportedly halved usage limits for Grok Bot over the weekend, a move confirmed by user reports and Elon Musk’s comments on X. The CEO stated that running costs for the agent are unsustainably high relative to revenue, though he did not issue a formal confirmation of the quota reduction. One affected user noted waiting days to receive a fresh allocation, prompting Musk to suggest that a larger subscription might be too expensive. This adjustment follows Musk’s declaration just two weeks prior that Grok was his fastest-growing product, a claim supported by SpaceX president Gwynne Shotwell’s earlier report of 800,000 weekly paying users.
The change signals a shift toward stricter cost management for AI agents that perform complex tasks like browsing websites and logging into accounts. While competitors such as OpenAI and Anthropic are also tightening flat-rate plans or charging significantly more for agent capabilities, SpaceX’s move specifically targets the economics of its own rapid expansion. The decision reflects the inherent tension between scaling autonomous tools and managing infrastructure expenses.
- Quotas are shared across Grok, the coding platform Cursor, and the bot itself
- Users reported waiting days for a new allocation after the cut
- OpenAI is merging Codex and Chat quotas starting in December
