Tencent Hunyuan Hy4 Preview Is Now Available on ApiHub

Another major Chinese AI model just joined ApiHub: Hunyuan Hy4 Preview.

Hy4 Preview is Tencent’s new-generation MoE flagship model with:

• 770B total parameters

• 49B activated parameters per token

• 1M context length

But the interesting part isn’t just the size.

Hy4 Preview is built heavily around Agents, Coding, and productivity — with stronger capabilities for understanding complex tasks, planning multiple steps, using tools, and continuing execution over longer workflows.

Tencent says the new generation makes meaningful progress in real-world work such as software engineering, document and spreadsheet analysis, game development, and scientific research. It’s also designed to handle long-horizon development tasks with better planning, debugging, verification, and context continuity.

We’ve now added Hy4 Preview to ApiHub, so developers can access it through the same API alongside DeepSeek, Qwen, GLM, MiniMax, and other models.

No need to maintain another separate provider integration — just switch models and start testing.

What would you try first with Hy4 Preview: coding, agents, long-context tasks, or productivity workflows?
