Aug 28 (Reuters) – 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.
