NetHack transpiler contest: serteal first to hit 100% on all public test sessions
davidbau · x · 2026-11-14
David Bau reports that Alex Serrano (serteal) has become the first NetHack transpiler contest entrant to pass 11,405/11,405 public sessions and 10,424/11,265 held-out ones, proving the transpiler approach generalizes rather than overfits. Bau interviewed him in Berkeley and handed over an unofficial mimic trophy. Key caveat: Phase 1 faithful-imitation is only a qualifier — December's Phase 2 will reward maintainable JavaScript that can absorb updated specs, where a transpiled C state machine may struggle. Runner-up NoahBPeterson sits at 99.9% PRNG/screen match with six screens to go. The contest remains wide open.
