Definition
Plain language
A well-known AI researcher whose small open-source training projects are widely used as starting points.
As stated in the literature
Andrej Karpathy; author of widely used minimal open training codebases (nanoGPT, nanochat) and open automated-research loops that serve as reference scaffolds in agent research.
Also called: Andrej Karpathy
Why it matters: Small, readable reference implementations lower the barrier to running real experiments, so more people can test ideas instead of just reading about them.
For example, a researcher wanting to test an idea about training small language models will often start from one of his compact open codebases rather than building from scratch.
