- The N64 demo uses period-accurate GCC 2.7.2; displayed timing is simulated, but compiler scores are real.
Field notes
The workflow gives each agent a function's machine code, the strongest prior attempt, and notes from earlier contributors. The coordinator compiles submitted C with a pinned original compiler, compares the output, and shares discoveries through a common header. The page specifies a sandbox with no network, a 2 GB limit, and a 30-second limit; it also notes that the single-machine coordinator may sleep during the early build.
