In Depth: How China’s Quant Funds Became AI Incubators

[para. 1] DeepSeek's launch of a low-cost, open-source AI large language model (LLM) in January marked a significant competitive movement against industry leader OpenAI. This development highlighted China's emerging leadership in AI, interestingly financed by a relatively obscure quantitative fund.[para. 2] Hangzhou-based High-Flyer Asset Management (Zhejiang) Co. Ltd., led by stock trader and AI enthusiast Liang Wenfeng, was the driving force behind DeepSeek. Their AI chatbot emerged from their use of AI algorithms for financial market strategies. [para. 3] Other quant funds like Ubiquant Investment and Beijing Renaissance Era Investment Management are also involved in AI and LLMs, with many actively recruiting to enhance their AI capabilities as market competition escalates.

[para. 4][para. 5] Ubiquant researchers co-authored a paper indicating they reproduced DeepSeek-R1, introducing a novel approach named "Logic-RL" for enhancing LLM reasoning through rule-based reinforcement learning (RL). This research demonstrates that complex reasoning capabilities can develop in LLMs through targeted RL, challenging previous assumptions and expanding the functional capabilities of AI models.

[para. 6] Various Chinese quant funds are deeply engaged in different stages of AI model training. While firms like High-Flyer and Ubiquant focus on high-cost pre-training of LLMs, others participate in post-training, refining LLMs for industry-specific applications, known as vertical fields. For example, Renaissance Era reports advancements in biomedicine via AI model collaboration with research institutions, with findings under peer review for Nature concerning a novel genetic hypothesis generated through AI.[para. 7] Baiont Quant focuses on AI developments in process management, production, and R&D for local businesses.

[para. 8] Comparing funding trajectories, the U.S. AI sector relies on tech giants, venture capital, and government grants, while Chinese tech firms like Alibaba and Tencent focus on their business models. However, Chinese quant funds have inadvertently supported AI model development, compensating for risk-averse VC and PE funds that shy away from high-risk AI investments.

[para. 9][para. 10] DeepSeek's introduction highlighted the pivotal role of Chinese quant funds in fostering AI innovation. A representative of a quant firm noted the contrasting investment philosophies; Chinese VC/PE investors favor straightforward business models, unlike U.S. backers of ventures like OpenAI.

[para. 11] Quant fund founders, viewing their firms as data-driven research entities, see the application of AI in quantitative trading as a natural progression. Quant trading's math and computation-heavy approach aligns seamlessly with AI research needs.

[para. 12] Many quant firms were established by individuals with scientific and technical academic backgrounds. Liang Wenfeng of High-Flyer applies his expertise in electronic and information engineering to financial markets, founding DeepSeek to focus on advanced AI models.

[para. 14] While DeepSeek and Ubiquant emphasize resource-heavy LLM pre-training, other AI endeavors in China focus on lower-cost post-training, enhancing models for particular tasks and refining through RL with feedback. These specialized AI tools, akin to app proliferation post-OS launches, represent potential broad industrial applications.[para. 15] China's LLM sector has matured into a comprehensive ecosystem from pre-training to specialized applications, signifying readiness for significant AI tools expansion.
