Three years ago, Liang Wenfeng’s quantitative hedge fund firm apologised profusely to investors for losing money during a tumultuous period for China’s stock market.
It was a surprising stumble for Zhejiang High-Flyer Asset Management, which used artificial intelligence to pick stocks and had grown rapidly to become one of the country’s largest quant funds. As the firm navigated through that crisis and its assets shrunk by more than a third from a peak of more than US$12-billion, behind the scenes Liang was laying the groundwork for a new AI start-up, DeepSeek.
DeepSeek, which grew out of High-Flyer, is now threatening to upend the global AI supply chain and challenge the seemingly-unassailable US lead in critical frontier AI technologies. The sudden popularity of the 20-month-old firm’s breakthrough technology and its namesake app sparked a massive US and European stock rout on Monday, wiping out close to $1-trillion in combined market value from chip giant Nvidia and peers.
It has also drawn shock and awe over how Liang, an engineering graduate who has never studied or worked outside of mainland China, pulled off such a feat. He has demonstrated that with local AI engineers, constrained access to the latest semiconductor technologies and limited resources, it is possible to match — and even surpass — the best in the field.
“Every country in the world could have that kind of a project going on, if they can acquire the talent and be able to work on it, of course. The rest of the industry is going to learn from this,” said Shuman Ghosemajumder, co-founder and CEO of Reken, a San Francisco-based AI start-up.
The question now gripping investors, companies and policymakers is whether AI requires hundreds of billions of dollars in capital expenditure to come up with the latest innovations and vanguard AI models — and whether export controls can hold off Chinese competition.
‘China’s Sam Altman’
Liang has been compared to OpenAI founder Sam Altman, but the Chinese citizen keeps a much lower profile and seldom speaks publicly. “OpenAI is not a god and cannot always be at the forefront,” Liang told Chinese media outlet 36Kr in July 2024.
The previous year, Liang said more investment doesn’t necessarily lead to more innovation. He has also opined on how Chinese companies have long been mostly followers as opposed to technology innovators. The problem has been a “lack of confidence and not knowing how to organise high-density talent to achieve effective innovation”, he was quoted as saying.

Liang was born in 1985 in Zhanjiang, an economically poor city in China’s southern Guangdong province. His father was an elementary school teacher. He studied electronic engineering at Zhejiang University, a prestigious college in the city of Hangzhou, and also earned a master’s degree in information and communication engineering there.
High-Flyer was as much an outlier in China’s quant industry as DeepSeek is to the global AI industry.
Liang and two of his former university classmates started dabbling in domestic stocks in 2008. Unlike the founders of most Chinese quant funds, none of them had overseas or institutional trading experience.
The trio tried different strategies from discretionary trading to arbitrage, before settling on using a systematic approach to implement trading ideas in 2015, the year they set up High-Flyer. They initially built a model based on price-and-volume factors, before trying machine learning in 2016.
The new tool allowed the firm to dig deeper to find new factors and identify “non-lineal” connections between factors, its CEO Simon Lu said in an interview in 2020. The founders integrated machine learning into High-Flyer products in 2018.
AI allowed High-Flyer to achieve “a lot of innovations” and develop a multi-strategy, multi-cycle investment model to “pile up” returns from different sources of returns, according to a 2020 brochure for the firm. Its flagship product benchmarked against the CSI 500 Index integrated low-risk strategies like intraday trading, allowing it to beat the gauge by a combined 120 percentage points in the previous three years, it showed.
High-Flyer grew assets quickly as a result, reaching more than C¥90-billion in 2021 before it stumbled later that year.
In December 2021, after experiencing record drawdowns at some funds, High-Flyer said its AI mistimed some trades and performed poorly during periods of large stock swings. “We feel deeply guilty,” it told investors. The firm also stopped accepting fresh inflows and said it would reduce its assets under management and adjust its strategies.
Three months later, its marketing head warned that certain volatility-sensitive clients should redeem their money — a highly unusual move.
Last year, High-Flyer said it would wind down products that had made two-way bets on the markets, and focus on “long-only” strategies in which it took only bullish positions on stocks. Its assets under management have dropped to around C¥60-billion.
Nvidia GPUs
DeepSeek’s research was funded by High-Flyer’s R&D budget, Liang said previously. It drew computing resources from the quant fund, which had amassed 10 000 Nvidia GPUs in 2021, prior to US bans on exports of sophisticated Nvidia chips and other graphics processing units.
Liang recruited engineering talent almost exclusively from China. Many were fresh out of top universities, interns in their final leg of doctoral studies and Olympiad medal holders.
“He’s a nerd but nerd in this context is not a negative,” said Zihan Wang, a PhD student at Northwestern University who did a six-month internship at DeepSeek in 2024.

Wang said Liang ran many experiments on his own, and DeepSeek operated much like a research lab. “It started small, but as they got real progress, they started to get excited,” he said.
The start-up began periodically releasing models, seemingly impervious to — even stirred up by — the US ban on exports of cutting-edge AI accelerator chips.
DeepSeek released its R1 advanced AI reasoning model on 20 January, the same day Donald Trump was sworn in as America’s 47th president.
Earlier that Monday, Liang attended a closed-door business symposium in Beijing that was hosted by Chinese Premier Li Qiang. There, experts in technology, science, education and other fields offered their opinions and suggestions for a draft government work report, according to the official Xinhua news agency. Video footage on YouTube shows Liang sitting across the table from Li and speaking, with the Chinese leader nodding attentively.
Significantly, DeepSeek open sourced its R1, allowing researchers and developers to freely use, modify and commercialise the model. That sent a signal that it wants to collaborate and innovate with others in the global AI community.
Liang stands out among Chinese entrepreneurs because of that non-commercial goal, his laser-focus on research and the realisation of artificial general intelligence, said Thomas Qitong Cao, assistant professor of technology policy at Tufts University in Medford, Massachusetts.
Liang is assumed to own 51% of High-Flyer. That would give him a stake worth $71-million based on a comparative analysis. If DeepSeek reaches the same potential as OpenAI, valued at roughly $150-billion, the founder could potentially be in line for a massive windfall.
Some have questioned whether Liang’s DeepSeek is as promising as it appears. Shortcomings include the start-up’s infrastructure’s ability to handle global traffic waiting to try its service, or the app’s handling of sensitive subjects such as the 1989 protests in Tiananmen Square and queries on Chinese leader Xi Jinping.
Experts have also questioned the assumption that DeepSeek was building with 10 000 A100 Nvidia chips, with analysts like Dylan Patel speculating that DeepSeek needs at least 50 000 of Nvidia’s far-more powerful chips, the H100s. Meta Platforms, for instance, operates the equivalent of 600 000 Nvidia H100s.

Still, Liang is prompting a rethink and re-calibration in the global AI ecosystem. It’s made it obvious that the “AI race won’t be won by creating the most sophisticated model; it’ll be won by embedding AI into business systems to generate tangible economic value”, said Mike Capone, chief executive officer of Qlik, a data analytics and artificial intelligence platform. — (c) 2025 Bloomberg LP
