About
Walter J. Troiani Vargas — computer and data scientist. I care about language models, world models, and the infrastructure that makes them cheap enough to iterate on.
I have worked on LLVM / OpenMP at BSC, research computing at CERN, and GPU platforms at Multiverse. On the side I am building Troiani, an open sub-billion model family from scratch, and a World Model Platform that is supposed to run a full train–serve loop.
This site is the notebook: writing first, then a library of LLMs, world models, and AI infra.
The previous version is still up — a Windows 2002 desktop.
