xAI Wants 1.2 Million NVIDIA GPUs for Colossus 2, Because Apparently “Too Much” Is for Other People

Right, so Elon’s xAI is reportedly aiming to cram up to 1.2 million NVIDIA GPUs into its next AI monstrosity, Colossus 2. Because when you’re already running one of the biggest GPU clusters on the planet, the obvious next step is to set fire to even more money, power, cooling, and supply chains just to see what happens. Sensible? Of course not. Spectacularly overblown? Absolutely.

The article explains that Colossus, xAI’s current AI supercomputer in Memphis, already uses a ridiculous number of GPUs, and now the company wants to scale the whole bloody thing into something vastly larger. We’re talking about infrastructure on a scale that makes ordinary enterprise IT look like someone running Exchange on a knackered beige box under a receptionist’s desk.

Naturally, this kind of expansion isn’t just about buying shiny silicon and stacking it to the ceiling. It means power delivery, cooling, networking, rack space, supply logistics, and construction all become nightmare-level problems. You don’t just order 1.2 million GPUs like you’re stocking up on printer paper, you daft bastards. Every layer of the system has to be engineered so the whole expensive pile of shit doesn’t melt, stall, or fall over the moment somebody launches a training run.

And yes, NVIDIA stands to benefit massively, because of course it bloody does. In the current AI gold rush, they’re the arms dealer selling shovels, tanks, and the entire damn battlefield. If xAI actually gets anywhere close to this target, it would further cement NVIDIA’s position at the center of the AI infrastructure feeding frenzy.

The piece also underlines the wider point: the AI race is no longer just about clever models and smug press releases. It’s about who can build and feed the biggest compute beast without the local grid collapsing in disgust. The winners aren’t just the firms with algorithms, but the ones that can secure hardware, electricity, real estate, and enough cooling to keep a small artificial sun from cooking Tennessee.

In short, xAI’s plan for Colossus 2 is an absurdly ambitious, probably eye-wateringly expensive attempt to build one of the largest AI systems ever conceived. If it works, it’ll be a landmark in large-scale AI infrastructure. If it doesn’t, it’ll still be one hell of an expensive bonfire made of GPUs, ego, and bullshit.

Reminds me of a sysadmin I knew who insisted the answer to every performance problem was “add more hardware” until the server room sounded like a jet engine and the UPS screamed like it had seen the devil. Turned out the real issue was a crap query and one profoundly useless architect. Business as usual, really.
