Musk reportedly wrote that Grok's agent was unsustainably expensive to run

What happens when an AI assistant becomes so popular that it costs more to run than it brings in? That question arises after a reply from Elon Musk on X on Sunday, November 1, 2026.

A request to reset

A user asked Musk to reset Grok Bot's weekly usage pool. The user wrote that they and many others had used up the pool significantly faster than normal. Another user wrote that they hit 100 percent of their limit with four days left until the reset, even though that does not normally happen. It has not been checked whether this applies to all users.

According to Tesla North, Musk replied that the cost of running Grok Bot was unsustainably high relative to revenue. The original post on X has not been read, so it has not been directly verified. He used the past tense. Tesla North therefore assesses that the tighter limits were deliberate cost control and not a technical error. That is an assessment, however, not a confirmation from xAI.

Musk said nothing about price changes, resetting pools, the size of the costs, a timeline or a shutdown. According to Tesla North, xAI has not issued a separate public statement.

Why is an agent expensive?

Grok Bot is an AI assistant from xAI that carries out tasks in the background, for example research, writing and browsing the web. It launched in August 2026. That kind of task requires more computing power than regular chat, and it costs money every time.

According to Runtime Wire, Grok Bot is bundled with subscriptions starting at around $30 a month. The outlet writes that under the current flat prices, the cost per task exceeds the revenue per user.

Many users, tough math

Bots n' Beans writes that Grok Bot had around 800,000 paying weekly users at the beginning of October. According to the site, the figure was given by SpaceX COO Gwynne Shotwell at the quarterly earnings call, as cited by MarketWatch, but the original source has not been verified. According to Bloomberg, a presentation in September mentioned around 418,000 weekly users.

According to the consumer guide RoboRhythms, Grok uses a shared weekly usage pool for chat, voice, images, video and Build. The plans cost $8 (Plus), $30 (Premium), $100 (Super) and $200 (Ultra). High-quality video and images drain the pool fastest. The plans and the pool apply to Grok in general, and Grok Bot draws on the same pool only for certain plans. The guide is not specifically about Grok Bot.

What could it mean?

Runtime Wire assesses that the industry may need usage limits, extra charges for overuse or special enterprise pricing if agent products are to add up financially. For regular users, it could mean running into caps more often, or that heavier use becomes more expensive. Nothing concrete has been announced, however.
