Yingke has learned that Nanjing Silicon Intelligence Technology Group Co., Ltd. (hereinafter referred to as "Silicon Intelligence"), an AIGC unicorn, recently completed hundreds of millions of yuan in Series D financing. The investor is the Industrial Fund of Jiaxing High - tech Zone (Xiuzhou District, Jiaxing). The funds from this round will be mainly used for R & D innovation investment, promoting the implementation of technologies, and accelerating the market - oriented application of products.

Since its establishment in 2017, "Silicon Intelligence" has completed more than one billion yuan in 10 rounds of financing. Its investors include Tencent, Sequoia Capital China, CMBC International, Zhongcai Qihoo, Haisong Capital, etc. The company focuses on the R & D and commercial application of AIGC digital human technology. It proposes to take silicon - based labor as the core and has built four product lines: the DUIX intelligent interaction platform, the virtual live - streaming platform, the video production platform, and the intelligent customer service.

With the rapid development of technologies such as large AI models, computer vision, and speech synthesis, the digital human industry has risen rapidly in China. The virtual avatars generated through AI technology can simulate human appearance, voice, and expressions and have interactive capabilities. They are widely used in fields such as live - streaming, customer service, education, and entertainment.

According to a report by iResearch, the market size of digital humans in China exceeded 10 billion yuan in 2023 and is expected to reach 30 billion yuan in 2025, with a compound annual growth rate of over 50%.

Currently, a large number of AI Agents have emerged in the market. As the inference cost of large models continues to decline, the technical threshold and commercial barriers of simply providing logic and process automation capabilities will quickly disappear. "Purely instrumental Agents will definitely end up in a fierce price war," Sima Huapeng, the founder of "Silicon Intelligence", told Yingke.

Sima Huapeng pointed out that the intelligentization level of many industries still remains in the primary stage. In fact, there is a widespread demand for high - quality Agents. AI naturally has the ability of a thinking chain based on logical reasoning and can solve problems in an absolutely rational way. On this basis, the digital human intelligent agents derived from it have also begun to enter more scenarios that require in - depth reasoning.

"For example, a doctor's inference of a disease is essentially a process of using professional knowledge to conduct a thinking - chain derivation based on information such as the evidence chain and patient characteristics," Sima Huapeng said. "There are a large number of thinking - chain application nodes in all industries. In the future, these nodes may gradually be taken over by AI, forming a 'human - machine collaboration' work model. That is, AI processes standardized links with thinking - chain logic, while humans focus on more core areas such as creative decision - making and emotional interaction."

The algorithm technology platform is the underlying support for the digital human product system of "Silicon Intelligence". In November 2024, "Silicon Intelligence" launched the new - generation multimodal large model DUIX ONE in the form of an API. This model integrates core algorithm capabilities such as speech recognition, speech synthesis, NLP, and computer vision and can provide multimodal capabilities such as seeing, listening, speaking, high emotional intelligence, and having a real - time human image.

Its advantage lies in greatly enhancing the sense of reality in interaction and effectively solving the problem of traditional digital humans being "similar in appearance but different in essence". At the same time, it also has stronger universality and application potential when entering the market - oriented implementation stage.

In terms of speech technology, DUIX ONE can accurately recognize speech content with different accents and speaking speeds and ensure stable operation in noisy environments. It has high accuracy and strong anti - noise ability. Then it can generate natural, smooth, and emotional human voices, achieving an effect close to that of real human voices.

In terms of digital human image construction, "Silicon Intelligence" can quickly and accurately create highly realistic face models through complete face modeling technology. The virtual image driving algorithm can drive the facial expressions and body movements of digital humans in real - time based on inputs such as speech and text, ensuring the vividness and naturalness of their actions.

In the interaction environment, DUIX ONE can deeply understand the semantics and emotions behind human language and provide functions such as intelligent dialogue, text classification, and knowledge Q&A. During this period, the digital human will generate replies with rigorous logic and rich content according to the dialogue scenario and user needs.

In terms of commercialization, "Silicon Intelligence" adopts a differentiated product strategy and provides customized service solutions for enterprise customers and individual users. For the enterprise market (2B field), the company focuses on serving customers such as operators, e - commerce platforms, and media institutions. Through standardized API interface services, it realizes the modular output of AI capabilities, significantly reducing the technical application threshold for enterprises.

Taking the e - commerce live - streaming scenario as an example, enterprise customers can quickly complete the personalized customization of a digital human anchor on the AI training platform by providing about 5 minutes of video material. The platform supports full - dimensional feature modeling of appearance, voice, and language style, highly restoring the characteristics of real human anchors. The generated digital human anchor also has real - time intelligent interaction ability, can accurately understand the questions from the audience, and respond according to the comments, enhancing the interactivity in the live - streaming room and increasing the audience retention rate.

The implementation and application of Silicon digital humans in various industries

Currently, the revenue of "Silicon Intelligence"'s digital human business has reached hundreds of millions of yuan. It has provided digital human anchor solutions for more than 5,000 cooperative brands, helping merchants reduce costs by about 80%. In the financial industry, it has cooperated with more than 30 banks and insurance companies and deployed intelligent customer service digital humans. It has also cooperated with mainstream TV stations to develop virtual hosts, etc.

For C - end users, "Silicon Intelligence" has launched a digital human "cloning" service to help users create their own digital avatars and achieve personalized functions such as virtual image customization and intelligent companionship. At the same time, on the DUIX intelligent interaction platform and video production platform, ordinary users can easily complete professional - level creations such as "digital human video generation" and "digital human real - time interaction", further lowering the threshold for digital content creation.

Yingke has learned that "Silicon Intelligence" has reduced the price of the digital human cloning service to several thousand yuan. The production process uses a fully automated process. With just 1 second of video, it can complete the cloning of the image and voice. While ensuring quick delivery within 1 working day, it also significantly reduces the technical application cost.

The latest official data shows that the "Silicon Intelligence" platform serves more than 500,000 users. The daily user - generated content exceeds 500,000 pieces, and the cumulative AIGC live - streaming duration is over tens of millions of hours. Through the in - depth application of digital human technology in scenarios such as short - videos and live - streaming, more and more ordinary users are changing from passive content consumers to active content creators.

To further promote the popularization of AIGC technology, "Silicon Intelligence" has fully open - sourced the core technology of the DUIX platform. The currently released DUIX - Mobile version supports Android and iOS platforms. It provides a minimalist integration solution for developers. By simply calling three lines of core code, they can quickly embed digital human functions into their own product systems, shortening the development cycle and accelerating the large - scale implementation of digital humans in more industries such as entertainment, law, finance, education, and healthcare.

As digital humans that integrate the capabilities of AI multimodal large models and can have real - time conversations gradually penetrate into more fields and enter people's lives, this is not only a technological advancement but also redefines the way of emotional transmission. "Digital immortality" is expected to move from concept to reality. When human emotions and memories are preserved across time and space through digital human technology, it also expands a new dimension for the form of life.
