The AI Buffet: Same Price, Smaller Portions
4 November 2026
On the Halloween weekend, many Grok Bot subscribers ran out of their weekly usage much faster than usual. Grok Bot is SpaceX’s AI agent, which carries out tasks for you rather than just answering questions. When a user asked for a reset, Elon Musk replied on X that the cost of serving Grok Bot was unsustainably high relative to revenue. Replit CEO Amjad Masad shared this with a warning: if your AI subscription is subsidised, expect it to change.
To be clear, the Grok Bot prices did not go up. Plans still cost $30 to $200 a month. What changed is how much usage you get for that price. And AI agent companies are rarely transparent about the exact measure of usage limits.
Compare this with normal software subscriptions. They work because one more user costs the company very little.
AI agents are different. An agent keeps working until a task is done, and every step uses computing power. So, to be fair to AI companies, a flat monthly fee for an agent is like paying someone a fixed salary with no limit on their working hours.
Subscribers only see their usage as a percentage. SpaceX (or name any AI company—OpenAI, Anthropic, Google) has never said how big the weekly pool is, and Grok Bot does not let users pick the model, so the company decides which model each task uses. This means the company can give less usage for the same price without announcing a price change.
There is a familiar comparison. Uber raises fares when demand is high, but it shows you the higher price before you book, so you can wait or choose another option. With Grok Bot, the change happened after people had already paid, and they could not see it.
I think we are discovering something interesting about AI agents. The technology is remarkably capable, but the business model is broken.
And when those economics become difficult, something has to give. Sometimes, it is the amount of usage customers receive rather than the price they pay.
It’s like paying a fixed price for an all-you-can-eat buffet, only to discover that the restaurant keeps reducing how much food you can eat.
