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.
