Tencent releases Hy4 model, now on TencentCloud, OpenRouter and Vercel AI Gateway

Tencent says its Hy4 model is available on TencentCloud and OpenRouter, and adds vision and computer use for the first time, along with stronger instruction following and long-context understanding.

Tencent's own announcement is the source for these capabilities. The report includes no independent testing or benchmark results.

Vercel says Hy4 is now on its AI Gateway at 50% off through December 31, 2026. Vercel describes Hy4 as adding image understanding and stronger agentic capabilities for long-running productivity tasks, a claim it makes without reported testing.
