Hugging Face uses small open models to reverse engineer a game binary byte-for-byte

yb2698 · x · 2026-10-26

Hugging Face researchers gave small, local open models a stripped game binary — no source, no symbols, no docs — and had them rebuild every function in Python until the port matched byte-for-byte on every tick. A lead agent coordinated small workers and, notably, rewrote their harness mid-run when workers kept repeating mistakes. The experiment builds on the viral Reverse Engineer Anything (REA) repo (370k+ GitHub stars), which the community has used to reimplement Adobe products and more. The write-up also covers what structural info can be extracted from compiled binaries.
