Tencent Hy4 now available on Vercel AI Gateway
Tencent's Hy4 model is now available on Vercel AI Gateway under the model name tencent/hy4, at 50% off through December 31, 2026. Hy4 supports reasoning, tool calling, structured outputs, and image input, with a 1M-token context window.
Why it matters
Builders can call Hy4 through a single AI Gateway API with usage and cost tracking, retries, and failover, at provider pricing with no markup or platform fee on inference, including BYOK requests. The 1M-token context window and vision input are relevant for codebase and multi-document work.
Who should care
Developers building AI agents, coding tools, document-processing pipelines, and applications that need vision or long-context models.
What you can do
Call the model with tencent/hy4 through AI Gateway, or run the latest Vercel CLI setup to use it in Claude Code, Codex, or Cursor.
