Elon Musk Says Grok Bot Costs Too Much to Run After Users Hit Weekly Limits Early

Some Grok Bot subscribers woke up on Halloween to a nasty trick. Their weekly usage meters had leapt, in some cases from as low as 50% to 100%, even though they said the agent had sat idle overnight. On Sunday, Elon Musk told them it was not a glitch.

"The cost of serving Grok Bot was unsustainably high relative to revenue" Elon Musk, replying to a user on X

That is the SpaceX CEO, in his own words, explaining why paying customers are running out of road early. TechCrunch reported that he made the remark in answer to a user's question and has not raised it on his main feed, where he has kept promoting Grok Bot as a gift-shopping helper.

Notice what he did not say. No cost figure. No revenue figure. No word on whether SpaceX actually cut allowances or what the limits will look like from here. Per Business Insider, he also asked one user whether the price jump to a higher-usage plan was "too high" and described cutting allowances and telling users about it as "just being sensible." It reads like a defence of tighter limits, not a confirmation of a specific number.

The Next Web reports that a user posting as Doge Norway asked Musk for a usage reset, saying plenty of people found their allowance "ran out really fast this week." No reset has been announced in the coverage we have seen.

A hit product with a bill attached

The timing is awkward. Under two weeks ago, on SpaceX's earnings call, Musk called Grok Bot "the fastest growth of a product that I've ever seen in my life." The company said it had more than 800,000 paid weekly users, and Musk added that the agent "may end up being what uses most of our Super Intelligence compute." SpaceX also said AI now makes up 52% of company income, and that its renamed Super Intelligence division booked a $431 million profit, according to TechCrunch. Without $1.2 billion in one-time costs from buying Cursor, that profit would have been higher.

So the division is profitable on paper, and the headline product is the one Musk now says costs too much to serve. Both can be true. Agents that run on a virtual computer and grind through tasks for hours are expensive in a way a chatbot reply is not. Business Insider notes that weekly refreshing caps, used by SpaceX and rivals such as Meta's Muse, exist to stop users from racking up huge AI bills. Tiers run from free to $200 a month, and the $200 tier is apparently not an escape hatch. We have not seen any figure showing how much of Grok Bot's cost is covered by subscriptions, and Musk has not supplied one.

Compute is the other thread. Musk has also said that SpaceX had locked in $40 billion for AI chips. If one agent could eat most of that capacity, the arithmetic of who gets to use it, and at what price, becomes the product.

Then there is the mockery. X users threw Musk's own recent line back at him, the one suggesting that saving money is pointless because AI abundance is coming. Developer Bruno Lemos summed up the mood in a post:

"23:59: saving money is pointless 00:00: we need to save money" Bruno Lemos on X

One caution before anyone blames it all on a cost squeeze. The Next Web notes that Cursor users saw weekly meters flip between 77% and 100%, and that Cursor reported a billing and usage dashboard problem on Sunday that was later marked resolved, citing Forbes. Nobody has said whether that bug explains any of the jumps. Musk's reply came after the complaints, and he pointed to cost, not a bug.

The real test is simple. Does SpaceX publish the new limits, and does it say what a $200 plan buys now? Until it does, paying customers are budgeting against a meter whose rules they cannot see, and Musk says that is just being sensible.
