Hy4 preview from @TencentHunyuan is here—and it’s now available on WorkBuddy.

We tested it inside real agent workflows across research, Office tasks, frontend development, and game development.

A few highlights:

→ Strong performance on research tasks that require finding, organizing, and synthesizing information
→ More capable Office workflows, from cross-file analysis to Excel accuracy and PPT visual layout
→ Better frontend execution, with stronger visual quality and interaction design
→ More capable game development, including building playable prototypes from natural-language instructions

What stands out most is how well Hy4 preview fits into end-to-end agent workflows — not just answering questions, but actually completing multi-step productivity tasks.

Hy4 preview is FREE to use on WorkBuddy for the next 2 weeks.

And Hy3 will remain FREE through the end of September.

Try Hy4 preview on WorkBuddy with your own real-world tasks and see how it performs.
