Asked on Sunday whether Grok Bot users could have their usage reset, Elon Musk answered with a line about money. “The cost of serving Grok Bot was unsustainably high relative to revenue,” he wrote on X at 20:34 GMT on 1 November. He gave no figures for Grok Bot cost or revenue, did not offer a reset and did not say what, if anything, had changed.
The reply matters because Grok Bot is sold with a usage allowance rather than unlimited use, and SpaceXSI, the SpaceX AI business that runs it, publishes no size for that allowance. Users who say theirs ran out days early now have an explanation of Grok Bot costs from Musk, but not from the company. TSN found no official notice that Grok Bot usage limits have changed.
Users said their weekly allowance ran out days early
The question came from the X account @DogecoinNorway at 20:11 GMT: “Any chance for a Grok Bot reset, @elonmusk? Lots of people say their usage ran out really fast this week.” Its post quoted another user who had written that afternoon that their Grok Bot usage stood at 100% with four days left until it refreshed. “Normally I don’t even reach 100%,” the user added.
About an hour after his first reply, Musk answered a second user who wrote that they had reached their limit and would have to wait until Wednesday to use their Bots again. “Upgrade to higher usage plan cost increase is too high?” he asked.
These are individual accounts, not data. Neither Musk nor SpaceXSI has said how many subscribers were affected or by how much.
Grok Bot cost comes out of a shared weekly pool
SpaceXSI’s pricing page, which TSN read on 2 November, sets out how the allowance works. “Every tier includes a pool of AI usage shared across Grok and Cursor,” it says. “Within Grok, the pool covers Chat, Imagine, Voice, and Bot. Higher tiers include larger pools, and usage costs vary by product.” The allowance “refreshes weekly, so one heavy day never wipes out your whole month”, and anyone who reaches it “can keep going with top-ups, or wait for your allowance to refresh”.
Grok Bot is listed from the Premium plan at $30 a month, which carries four times the usage of the $8 Plus plan. Super, at $100, offers 15 times Plus, and Ultra, at $200, offers 50 times. The page recommends Super “for daily agent users” and Ultra “for power users”. Because the pools are given only as multiples, there is no published number against which a subscriber could check whether their weekly allowance has shrunk.
These are the tiers SpaceXSI set out when it launched the X Subscription in October, bundling Grok, Grok Bot, Cursor and X Premium. The pricing page carries no notice of a change to the pools.
The Grok Bot changelog does record one change to how the product is sold. Version 0.78.1, released on 27 October, says: “Where Grok Bot offered a free trial, it now offers Get Grok Bot with a unified plan and See Unified Plans.” Two days later Musk posted: “Worth noting that Grok @Bot has no free tier.”
The Verge reads the reply as a sign of throttling
The Verge reported on 2 November that Musk “appears to have throttled Grok Bot”, saying he “hinted at the change” after users complained they were hitting usage limits sooner than expected, “without providing details on what has changed”. Anadolu described subscribers “reaching weekly usage limits much sooner than expected”. Neither cites a company notice, and Musk’s post on Grok Bot cost does not mention limits.
The complaints come as use grows quickly. On SpaceX’s third-quarter call on 20 October, President Gwynne Shotwell said Grok Bot had reached 800,000 paid weekly users, and Musk said he thought it “may end up being what uses most of our SI compute”, as TSN reported at the time. In the same month the official @bot account said a speed update meant computer tasks would finish “3x sooner on average”, and SpaceXSI has since let Bots build reports, memos and dashboards. SpaceX has not said what Grok Bot earns per user.
A past-tense reply leaves the size of the change unknown
Musk’s sentence is in the past tense. The cost “was” unsustainably high, which reads as a description of a problem already acted on rather than one still under review. Put alongside his question about upgrading, the most natural reading is the one The Verge drew: that each Bot task now draws more from the weekly pool, or that the pool itself is smaller. But that is still a reading. Nobody at SpaceX has said which lever moved, by how much or from what date.
That silence matters more for an agent than for a chatbot. Subscribers buy a plan on the strength of what their Bots can get done in a week, and the pricing page’s promise that “one heavy day never wipes out your whole month” holds only if the pool is large enough for that work. When each pool is described only as a multiple of another unpublished pool, any cut stays invisible until people run out.
The commercial pressure is also plain. Rapid growth in paid users is good news for SpaceX only if each one brings in enough to cover the Grok Bot cost of serving them, and Musk’s reply says that balance had tipped too far. Asking users to move to a dearer plan is one way to fix it, and his question about upgrading suggests that is the route he favours.
The pricing page says subscribers will “always see your remaining usage in settings”. A published pool size, or a changelog entry that names the change, would settle what happened. Until then, the clearest test is the next weekly refresh, which one of Sunday’s users said was due on Wednesday.
