Tencent Releases Open-Source Hy4 AI Model for Coding
Tencent has shown a new AI model called Hy4.
The model is designed to help with computer programming and research.
It may also be useful for financial analysis.
Hy4 is open-source, which means people can access and study its model.
It has many parts, but only some are used for each question.
Tencent says it may add Hy4 to products such as CodeBuddy and WorkBuddy.
Because this is an early version, it can take too long to solve difficult questions.
It may also check its answers more than necessary.
The article’s caption mentions an earlier model called T1, while the main text identifies the new model as Hy4.
Tencent released a preview of Hy4, an open-source AI model for coding, research and financial analysis.
Hy4 uses a mixture-of-experts design with 770 billion total parameters.
About 49 billion parameters are used for each text request.
Tencent plans to integrate Hy4 with CodeBuddy, WorkBuddy and other products.
Tencent cautioned that the early model may overwork complex questions and over-verify answers.
