Hy4 Preview from Tencent is now available on AI Gateway.
Tencent's Hy4 Preview is now available on AI Gateway, the unified model API from Vercel. It's an open-source Mixture-of-Experts model with 770B total parameters and 49B active per token, serving a 1M token context window and aimed at long-horizon coding, document analysis, game development, and scientific reasoning.
To use it, set the model to tencent/hy4-preview in the AI SDK, or run vercel ai-gateway coding-agents setup to select it inside coding agents such as Claude Code, Codex, OpenCode, Cursor, and Pi. It can also be tried in the model playground.
AI Gateway reflects provider pricing with no markup and charges no platform fee on inference, including on Bring Your Own Key requests.
