Founder |tiny corp / tinygrad
Founded tiny corp to commoditize the petaflop with tinygrad and the tinybox. Previously founded comma.ai (openpilot, 60k+ GitHub stars). First to jailbreak the iPhone and hack the PS3.
Biography
George Hotz (geohot) is an American hacker, entrepreneur, and software engineer born October 2, 1989 in Glen Rock, New Jersey. At age 17 he became the first person to publicly jailbreak an iPhone (2007), and later reverse-engineered the PlayStation 3's security (2010), prompting a high-profile lawsuit from Sony that settled in 2011. He interned at Facebook, won $150K from Google for Chrome exploits (2014), and joined Google's Project Zero elite security team. He won DEF CON CTF with Carnegie Mellon's PPP (2013, 2014) and placed first solo at NYU CSAW CTF (2013). In 2015 he founded comma.ai, building openpilot into the leading open-source driver-assistance system supporting 300+ car models (60k+ GitHub stars). He stepped down from day-to-day comma.ai leadership in October 2022, departed entirely in November 2025. He briefly interned at Twitter under Elon Musk in late 2022, resigning after four weeks. In November 2022 he founded tiny corp, raising $5.1M in May 2023 to build tinygrad (31k+ GitHub stars), a minimalist deep learning framework, and the tinybox, a $15,000 AI computer with petaflop-class performance. His mission: commoditize the petaflop. Tiny corp is building a fully sovereign AMD compute stack, rewriting the entire driver/runtime/library layer in roughly 12,000 lines of code. Based in San Diego, CA.
Minimalist deep learning framework aiming to be a balance between micrograd simplicity and PyTorch functionality. 31k+ GitHub stars. Written in Python with a fully sovereign AMD compute stack in ~12,000 lines. Powers comma.ai's openpilot on Snapdragon 845 GPU.
Open-source advanced driver-assistance system supporting 300+ car models. 60k+ GitHub stars. The leading open-source self-driving software, running on comma two, comma three, and comma 3X hardware devices.
$15,000 'luxury AI computer' with petaflop-class FP16 performance using six AMD GPUs. Designed to democratize access to AI training and inference by making local compute affordable for researchers and small teams.
Complete rewrite of the GPU compute stack for AMD hardware: custom driver, runtime, libraries, and emulator in ~12,000 lines of code, aiming to break NVIDIA's CUDA ecosystem lock-in.
In 2007 at age 17, became the first person to publicly carrier-unlock and jailbreak an iPhone, enabling third-party software installation and network carrier freedom.
Reverse-engineered the PS3's hypervisor and published exploits enabling homebrew software, leading to the landmark SCEA v. Hotz lawsuit and raising questions about digital ownership rights.
My central thesis about the world is there are things that centralize power and they're bad, and there are things that decentralize power and they're good. Everything I can do to help decentralize power I'd like to do.
CUDA isn't really the moat people think it is, it is just an early ecosystem.
AMD passed my cultural test. I now believe they aren't going to shoot themselves in the foot on software.
Will GPT-12 be AGI? My answer is no, of course not. Cross-entropy loss is never going to get you there. You probably need reinforcement learning in fancy environments to get something that would be considered AGI-like.
Hacking isn't about getting what you didn't pay for, it's about making sure you do get what you did.
Resigned from Twitter today. Appreciate the opportunity, but didn't think there was any real impact I could make there.
