K3 Autonomously Builds Web DOS Emulator
teortaxesTex · x · 2026-07-17
The author shared an extreme test result: a model/agent codenamed K3 ran continuously for several hours on a target task, hitting the roughly 1 million context limit twice, and managed to keep progressing after automatic compression.
It ultimately built a DOS emulator on the web, capable of directly running the ROM for Legend of Sword and Fairy (仙剑奇侠传). The process involved no third-party libraries; the model hand-wrote the implementation and adapted the disassembly itself. It only paused once for human assistance to test keyboard input and cross-checked against DOSBox, requiring almost zero human intervention.
