Tencent Hy4 Preview on Vercel AI Gateway

What shipped? Tencent's Hy4 Preview is now callable through Vercel AI Gateway as tencent/hy4-preview, with no provider account required.

What changed? The model joins AI Gateway's model catalog alongside Muse Image, Ling 3.0 Flash Fin, and others that landed this week. You call it with a single API key through Vercel's unified gateway, which adds automatic retries, failover across providers, spend tracking, and traces on every request. AI Gateway passes through provider pricing with no markup and doesn't charge a platform fee on inference — including BYOK requests.

Coding agents like Claude Code, Codex, Cursor, OpenCode, and Pi can use it after running vercel ai-gateway coding-agents setup and selecting the model.

Why a builder cares? Hy4 expands the frontier-model tier available without a direct Tencent account. For teams routing through AI Gateway anyway, this is a new option with zero configuration overhead — just a model string swap.
