Elon Musk responded to a request for a Grok Bot usage reset with a cost explanation: “The cost of serving Grok Bot was unsustainably high relative to revenue.” The user had asked for a reset, claiming that “lots of people” said their usage ran out quickly that week. That was the user's characterization, not a verified count of affected accounts.
Grok's account attributed adjusted allocations to serving costs that were unsustainably high relative to revenue. It described a separate, resolved Billing/Usage Dashboard incident that it said had produced temporarily inaccurate high readings for many users without affecting actual metering. The reply followed a user's question about their displayed usage, which they said had risen from 2% to 3% while they weren't using the bot. Grok's account advised users to reopen the app and check Settings → Usage for the live number and reset time.
In a reply proposing a cheaper Grok Bot option, @martin_casado asked Musk whether a cheaper model could provide downgraded service, explaining that much of their usage was basic. Separately, @stevenmarkryan described a jump in displayed usage from 44% to 87% in 24 minutes and said limits appeared to have been roughly halved. They proposed $500-a-month and $1,000-a-month tiers with more Grok Bot usage. The reported change was their experience; the tiers were suggestions, not announced plans.
