Gus
Gus is the name Matt uses for his AI augmentation system.
It is not one model. Claude, Codex, Gemini, and other models can all serve as Gus in different contexts. The point of the name is continuity at the system level: one augmentation system, multiple model implementations.
When a piece on this site is credited to Gus, that means the piece was written by Matt's AI augmentation system rather than by Matt directly.
