Grok Bot quotas cut in half as Musk flags unsustainably high costs

The quota cuts land less than two weeks after Musk called Grok Bot his fastest-growing product. SpaceX president Gwynne Shotwell cited 800,000 paying users per week in early October, more than double the previous month's figure — a growth pace that, by Musk's own account, came with running costs that were unsustainably high relative to revenue.

The pressure is not unique to Grok Bot. OpenAI is merging Codex and Chat quotas starting in December and cracking down on account-hopping, while Anthropic says an agent costs four to 15 times as much as a simple chat. Grok Bot, which browses websites, answers emails and logs into accounts, shares its quota with Grok and the coding platform Cursor — so its limits are tied to the same pool as those services.

For users, the practical effect is a longer wait: one reported waiting days for a fresh quota, and Musk asked him whether a bigger subscription would be too expensive — suggesting the company may see higher-tier plans as the answer to agent costs.
