Elon Musk throttles Grok Bot as serving costs surge

Over Halloween weekend, Grok Bot subscribers woke up to a nasty trick: their weekly usage limits were maxed out, even if they hadn't touched the AI overnight. Some watched their meters jump from 50% straight to 100%.

Elon Musk confirmed on Sunday that this was not a glitch. Replying to a user on X, he admitted the cost of running Grok Bot was simply "unsustainably high relative to revenue." He hasn't addressed the squeeze on his main feed, where he's still pitching the bot to help you shop for family gifts.

A rude awakening for power users

The sudden clampdown is a stark reality check. SpaceX recently disclosed that AI now makes up 52% of its income, and its rebranded Super Intelligence division turned a rare $431 million profit last quarter—even after absorbing a $1.2 billion one-time charge from acquiring Cursor. Musk himself recently dubbed it the fastest-growing product he has ever seen.

Yet agentic AI eats compute for breakfast. Musk hasn't specified how subscriber limits will change going forward, leaving paying users in the dark.

Why it matters

It looks like the flat-rate honeymoon for agentic AI is officially over. Unlike standard chatbots, agents that plan multi-step workflows burn through compute exponentially, making unlimited or generous caps nearly impossible to sustain on a monthly fee.

If an AI division banking hundreds of millions in profit still has to pull the emergency brake over server bills, everyone else is feeling the exact same pain. We think this will force the entire industry to shift toward tighter caps and aggressive metered billing for complex tasks.
