Built an FPS Game with Tencent Hunyuan Hy4, Testing Long-Horizon Coding Loops
techNmak · x · 2026-08-29
The author built an FPS game using Tencent's Hunyuan Hy4 Preview (770B params, 49B active, 1M context) inside WorkBuddy. The model targets long-horizon software work, handling large context spread across files and repeated iteration cycles—understanding, planning, debugging, and checking. Game development serves as a visible benchmark for this loop, evolving from a prompt to a playable prototype over multiple turns.
