Tencent Releases Open-Source AI Model for Coding and Research
Tencent has released an early version of a new computer program called Hy4.
It is designed to help with coding, research, and financial analysis.
The program is open-source, meaning people can inspect and use its model under its release terms.
Hy4 has many computer-learning parameters, but it uses only some of them for each question.
Tencent says it may add Hy4 to its CodeBuddy and WorkBuddy products.
Because this is an early version, it can sometimes take too long to solve difficult questions.
It may also check its answers more than necessary.
The release comes as Tencent is investing more in artificial intelligence.
Tencent previously released Hunyuan 3.0 and hired former OpenAI researcher Yao Shunyu to lead AI platform development.
Tencent released a preview of its Hy4 open-source AI model on Hugging Face.
Hy4 targets software engineering, research, and financial analysis tasks.
The model has 770 billion total parameters, with about 49 billion used per request.
Tencent plans to integrate Hy4 with CodeBuddy and WorkBuddy.
Tencent warned that Hy4 may overwork complex questions and over-verify answers.
