How we got this

Tencent is the maker of Hy4. We look at the gaps between its earlier versions (Hy3, 2026-04-22; Hy4, 2026-08-28) and project the next one. It is a guess from a pattern, not news: the maker has not said Hy4.1 exists. This page turns into the launch page, with price and facts, as soon as the model shows up on OpenRouter, Hugging Face or GitHub.
