Liang Wenfeng represents DeepSeek, and he represents himself.

At the World Internet Conference in Wuzhen, Zhejiang, the highly anticipated "Six Rising Stars of Hangzhou" made their debut on the same stage for the first time.

Academician Wang Jian, the founder of Alibaba Cloud, presided over the event. Xingxing Wang, the founder and CEO of Unitree; Bicheng Han, the founder and CEO of BrainCo; Xiaohuang Huang, the founder and chairman of Coohom; Ji Feng, the founder and CEO of Game Science and the producer of "Black Myth: Wukong"; Qiuguo Zhu, the founder and CEO of DeepRobotics... all took their seats.

Among the "Six Rising Stars of Hangzhou", DeepSeek, which attracted the most attention, saw its founder and CEO, Wenfeng Liang, still absent. Instead, it was —

Deli Chen, a researcher at DeepSeek.

Wenfeng Liang represents DeepSeek, and Deli Chen represents Wenfeng Liang.

But the question is, who is Deli Chen?

The New "Spokesperson for DeepSeek"

Only at the World Internet Conference in Wuzhen can we catch a glimpse of the latest thoughts within DeepSeek.

However, this time, it was not the founder Wenfeng Liang who took the stage to represent DeepSeek, but a researcher from DeepSeek — Deli Chen.

When asked how DeepSeek's success and its open - source model will drive the development of AI, this researcher representing DeepSeek and Wenfeng Liang first expressed optimism:

In the next three to five years, humans and AI will be in a honeymoon period, and the progress of AI can greatly assist humans.

But then, Deli Chen changed the subject and expressed his concerns about the continuous progress of AI:

Ten years from now, AI may replace the vast majority of jobs, and society will face huge challenges.

He emphasized that this is by no means alarmist. This round of AI revolution is fundamentally different from the previous two industrial revolutions.

In Deli Chen's view, no matter how advanced past technologies were, new inventions were always just "tools" dominated by humans; and humans, with their wisdom and creativity, always had the upper hand in the relationship between humans and technology.

However, the emergence of AI is rewriting this pattern — for the first time, technology begins to have autonomous "intelligence" and even surpasses humans in some aspects.

In this context, while AI replaces human jobs, it may not create new jobs as it did in the past. This will have an unprecedented impact on the existing social order and economic structure.

I am very optimistic about AI, but I think it may have a negative impact on society in the long run. At that time, technology companies need to play the role of "guardians".

His words were concise but profound, quickly sparking heated discussions.

It was even once interpreted that DeepSeek had joined the "camp of AGI pessimists". This seems to be a contrast when compared with other technology companies that prefer an optimistic narrative.

But "those who understand me know that I am worried". If we take a closer look at DeepSeek and Deli Chen, such thoughts are not surprising.

Deli Chen is an AI scientist and researcher. In his limited public sharing, he also represents DeepSeek in continuously sharing the alignment of AI values.

Who is Deli Chen?

Deli Chen joined DeepSeek in 2023 as a researcher, mainly responsible for core areas such as language models, alignment mechanisms, training strategies, and model generalization ability.

In the past two years, his name can be found in almost all of DeepSeek's important research achievements — whether it's V2, V3, or R1.

Google Scholar shows that Deli Chen's current citation count has exceeded 13,000, and this number has increased significantly this year.

2024 was a crucial year for DeepSeek to officially enter the LLM field. The team completed three major version iterations from V1 to V3 in just one year.

Therefore, at NVIDIA's annual GTC 2024 conference, it was no surprise that DeepSeek was invited to the stage for the third consecutive time to share their latest thoughts on cutting - edge AI.

It was also at this event that Deli Chen first appeared as a "researcher at Magic Square AI and DeepSeek" and gave an online speech titled "Harmony without Uniformity: Decoupling the Value Alignment of Large Language Models".

Deli Chen pointed out in his speech that once the values of traditional large models are written into the parameters, they almost become unchangeable stereotypes and are difficult to adapt to the diversity of human society.

To this end, DeepSeek proposed a new idea — "decoupling value alignment".

Simply put, it means splitting alignment into two parts: core values must be unified and adhere to the bottom line; diverse values are left to users for free customization. In this way, both safety can be ensured, and true "beauty in one's own way" can be achieved.

Simply put, it is — harmony without uniformity.

However, this speech also became DeepSeek's "swan song" on the GTC stage — the company did not attend NVIDIA's GTC conference in 2025.

After this appearance, Deli Chen disappeared for nearly two years. Except for Wenfeng Liang himself, DeepSeek has not sent any other team members to such public occasions.

Since then, Deli Chen has almost disappeared from the public eye, with no news for nearly two years.

Meanwhile, except for Wenfeng Liang himself, DeepSeek no longer sends any team members to similar public occasions.

Deli Chen graduated from Peking University with a major in Information Management and Information Systems.

In 2018, he was recommended to pursue a postgraduate degree at his alma mater with excellent grades. He entered the School of Electronics Engineering and Computer Science (EECS) at Peking University, officially stepping into the forefront of AI research.

During his master's studies, Deli Chen completed two important internships:

In November 2018, he went to the electronic trading department of Mizuho Securities in Tokyo, Japan, as a research intern for three months.

This experience related to quantitative research also laid the foundation for his later entry into Magic Square Quantitative.

In June 2019, Deli Chen joined Tencent's WeChat AI team for a three - month summer internship, mainly engaged in research on language understanding and graph neural networks.

In 2020, the Peking University laboratory where Deli Chen was located jointly published a research paper on graph neural networks (GNN) with WeChat AI, and Deli Chen was the first author.

In this paper, the team revealed the cause of the "over - smoothing" problem in GNN and proposed a verifiable mitigation solution.

As of now, this paper has been cited more than 1,500 times on Google Scholar.

In 2021, Deli Chen graduated with a master's degree and officially joined WeChat AI.

Two years later, he left Tencent and became a member of DeepSeek with his unique resume of "quantitative + AI".

"Spokesperson for Wenfeng Liang"

It can be said that Deli Chen's speech at the World Internet Conference in Wuzhen, Zhejiang, made him the second "spokesperson for DeepSeek" in public after Wenfeng Liang.

What makes Deli Chen's attendance even more eye - catching is —

Among the "Six Rising Stars" guests on the same stage, the large - screen introductions of the other five all carried the titles of "founder" or "CEO":

The founder, CEO, and CTO of "Unitree", Xingxing Wang.

The founder and CEO of "BrainCo", Bicheng Han.

The co - founder and chairman of "Coohom", Xiaohuang Huang.

The founder, CEO, and producer of "Black Myth: Wukong" of "Game Science", Ji Feng.

The founder and CEO of "DeepRobotics", Qiuguo Zhu.

So, in a sense, compared with the "spokesperson for DeepSeek" —

"Spokesperson for Wenfeng Liang" may be a more appropriate label for Deli Chen.

Wenfeng Liang represents DeepSeek, and Deli Chen represents Wenfeng Liang.
