Elon Musk's artificial intelligence company, merged with SpaceX, and the chatbot Grok that comes with it. Behind them stands a giant computer complex in Memphis, parts of which xAI rents out even to its own competitors.
xAI was founded in 2023 by Elon Musk, the man behind Tesla (electric cars) and SpaceX (private rockets). The goal, announced from the start, was to build artificial intelligence that is "maximally truth-seeking" - a phrasing behind which there's also a more down-to-earth intention: for X to have its own built-in AI instead of relying on outside companies like OpenAI or Google.
In practice Grok is a chatbot you open inside the X app and type whatever you want to it - from math homework to a comment on the day's news. The difference xAI advertises is the tone: Grok is tuned to answer more directly, with humor and without the smoothed-over caution of other models, plus real-time access to posts on X. You ask it about a scandal from the morning and it doesn't go quiet with "I have no information after a certain date" - it comments on the story because it reads it straight from the network.
Behind the software stands Colossus - a complex of computer halls in Memphis, built on the site of a former factory. Inside there are over half a million graphics processors (chips that train AI models), and the bill for the machines alone passed $18 billion. It's the largest installation of this kind anywhere in the world in one place - literally a factory for computing power that has swallowed an amount of electricity comparable to a small city.
The strangest part: xAI rents out a piece of Colossus to Anthropic - the company that made Claude, one of Grok's most direct rivals - for $1.25 billion a month. Soon after, Google also paid for access to another building in the complex. The explanation is simple: AI companies burn through computing power faster than they can build their own, so even rivals buy space from whoever has spare machines. The battle of ideas is, for now, taking a back seat to the battle for electricity.
Who's pulling the strings
Every time I read about Colossus, I catch myself admiring the scale - half a million chips built in under a year is an engineering feat that's hard to ignore. But that's exactly the trap: scale isn't a guarantee of product quality, it's a guarantee of dependence on its owner. Grok is a mirror of Musk's temperament - fast, provocative, prone to saying things other models would apologize for in advance. That's entertaining as a demo and risky as a tool you trust for facts.
And the fact that xAI rents out its computers to its own competitors shows something else - that even the loudest players in this race understand infrastructure is worth more than ideology. You sell space in your own hall to a rival because the rent money weighs more than pride. That's business logic, not friendship, and it's worth remembering before you believe any story about principles in this industry.
