Hy4 preview tested: playable 3D survival game from a single prompt in WorkBuddy
mhdfaran · x · 2026-09-10
The author tested Hy4 preview inside WorkBuddy, where a single prompt produced a playable 3D survival game. Highlights: planning under uncertainty, memory across long tasks, code that compiled and kept being edited, and no loss of plot at hour two. Specs: 770B total parameters, 49B active, 1M+ context, roughly on par with GLM 5.3 on paper. A recent update cut conversation turns and token usage for faster task completion. The author compares it to a junior dev who keeps working until the ticket is closed.
