Tencent's 770B Hy4 preview builds a playable 3D game from one prompt in agent test
HeyToha · x · 2026-09-05
Blogger @HeyToha tested Tencent's Hy4 preview inside WorkBuddy with a single instruction: "build me a playable 3D game from scratch."
- The model planned the game structure, generated code across files, built UI and interactions, debugged, and iterated while keeping context;
- Specs: 770B total parameters, 49B active, 1M-token context window;
- Positioned for coding agents, game development, tool use, and other long-horizon workflows;
- Free to try in WorkBuddy until September 10.
Note the promotional tone — treat as an anecdotal demo rather than a rigorous benchmark.
