China's Tencent releases new open-source AI model for coding, research tasks

Tencent released a preview version of a new open-source AI model aimed at tasks such as software engineering, research and financial analysis, according to its post published ‌on Friday ⁠on ⁠Hugging Face, a repository of open-source AI models.

The model, called Hy4 preview, uses a "mixture-of-experts" ​design with 770 billion parameters in total, Tencent said, although only about ​49 billion are used ⁠for any ‌given text request.

The ​Chinese ​technology giant said it plans ⁠to integrate the model alongside Tencent ​products, including CodeBuddy and WorkBuddy.


​Tencent added that the early-release model can sometimes take longer than necessary to work through complex questions and may over-verify its own answers.

‌The release comes at a time when Tencent is ramping ​up investment ​in AI ⁠in an increasingly crowded market.

It unveiled a large language model called Hunyuan 3.0 ​in April, its first major release since hiring former OpenAI researcher Yao Shunyu to lead its AI platform development.
