George Hotz
Creator of the open-source tinygrad deep learning framework and founder of tiny corp and comma.ai
George Hotz started tinygrad in October 2020 and founded tiny corp, the computer company that maintains it; tinygrad is an end-to-end deep learning stack released under the MIT license. George Hotz's blog describes tiny corp's stated goal as "to commoditize the petaflop" and describes tinygrad's stack as spanning a frontend, a graph compiler, runtimes, and GPU drivers. George Hotz's homepage also points to comma.ai as one of George Hotz's startups; comma.ai develops openpilot, an MIT-licensed operating system for robotics that upgrades the driver assistance system on supported cars.341256
Products and projects
George Hotz's homepage points to two companies Hotz started: comma.ai and tiny corp. comma.ai develops openpilot, an MIT-licensed operating system for robotics that upgrades the driver assistance system on supported cars, and sells hardware for hands-free driving in existing cars.168
In May 2023 Hotz announced tiny corp on the blog, describing it as a computer company whose goal is "to commoditize the petaflop". The company sells tinybox, a configurable deep learning computer, through tinygrad.org.37
Open-source work
Hotz started tinygrad in October 2020, with a first commit on October 17, as a small project for learning about neural networks. By 2023 it ran the driving model inside openpilot, and its intermediate representation was built from a small set of operations so that matrix multiplies and convolutions reduce to multiplies and sums with lazy evaluation allowing operation fusion.43
Hotz's December 2025 post "Five years of tinygrad" describes the stack as including a frontend, a graph compiler, runtimes and drivers, with work under way to remove the LLVM dependency so tinygrad can drive AMD GPUs in pure Python. The post describes tiny corp as working almost entirely in the open on GitHub and Discord, with contributors hired through their contributions to the repository.45
