About
Hy4 is Tencent Hy's flagship large language model, released November 4, 2026 as the successor to Hy4 preview. It is the first Hy model with vision input, and Tencent serves it on Tencent Cloud, OpenRouter and in its CodeBuddy, WorkBuddy, Yuanbao and ima products. Tencent says it plans to open-source the weights, with vLLM and SGLang support and a system card at that time; as of release the model is API-only.
