Profile

George Hotz — known online as geohot — is a hacker in the original sense of the word: someone who takes systems apart to understand them, publishes the teardown, and dares you to stop him. He became famous at 17 for the first iPhone jailbreak in 2007, then earned a lawsuit from Sony for jailbreaking the PS3. Two decades later he is one of the most watched independent AI engineers on the internet, mostly because he live-codes everything and refuses to treat any software stack — CUDA, LLVM, PyTorch — as sacred.

In 2015 he founded comma.ai, a company built on the heretical bet that a $1000 dashcam-sized device running open-source software (openpilot) can deliver Level 2 autonomy as good as Tesla Autopilot. It works, ships to real drivers, and has probably the most honest self-driving engineering culture of any company in the space — engineers post their commits publicly and the whole thing lives on GitHub. His famously combative meeting with Elon Musk about joining Tesla is part of the origin story.

What matters most to developers learning AI today is tinygrad and his new company the tiny corp. tinygrad is a ~10k-line deep learning framework that implements the minimum viable autograd, lazy tensor, and kernel compiler — and nothing else. Reading tinygrad is the fastest way on Earth to understand what PyTorch actually does under the hood: how a matmul becomes a kernel, how backprop works when you can hold the entire graph in your head. Hotz live-streams the development on YouTube, bugs and all. For anyone coming from a Chip Huyen book or an Andrej Karpathy lecture wanting to go one level deeper into the metal, this is the move.

He is also on a crusade against NVIDIA’s moat, writing open-source drivers for AMD GPUs so consumer cards can run AI workloads without the CUDA tax. Whether or not tiny corp succeeds as a business, the body of work he’s putting in public is a gift to anyone trying to understand AI infrastructure from first principles. Loud, abrasive, sometimes self-sabotaging — but almost nobody in the field shows their work this openly.
