# Tencent releases Hy4 as an open-weight model with vision and computer use, claiming top-tier status among Chinese open models

Tencent released its Hy4 foundation model with open weights on Nov 4, 2026, adding vision and computer use to the August preview; Bloomberg reports Tencent says it joins the top tier of Chinese open-weight AI for the first time, with a Flash version planned.

## Key facts
- Nov 9 (SCMP, per Techmeme headline; SCMP blocked for us): Tencent chief AI scientist Yao Shunyu said AI's biology abilities will soon make it 'possible to do harm' and that Anthropic has a 'strong argument' for closed models
- Adds vision and computer use (Pandaily)
- Flash version planned (Bloomberg)
- Hugging Face: no Hy4 repo under the tencent org yet when checked (Nov 4); only the Oct Hy4-preview derivatives by third parties
