DeepSeek is a Hangzhou artificial-intelligence company, owned by the hedge fund High-Flyer, that releases open-weight large language models.
DeepSeek is a Chinese AI company founded on 17 July 2023 by Liang Wenfeng and backed by High-Flyer, the Hangzhou hedge fund he also co-founded.1 It develops open-weight large language models and an eponymous chatbot.1 The January 2025 release of DeepSeek-R1 made the company a global reference point for low-cost reasoning models.1 Later press reports of fundraising and valuation are recorded as reported, not as audited capitalization.
History
Liang Wenfeng co-founded High-Flyer in 2015 and later built GPU clusters used for quantitative trading.1 High-Flyer announced an AGI lab in April 2023 and spun it out as DeepSeek on 17 July 2023.1 The company released models through 2024 and a widely discussed R1 reasoning model in January 2025.1 Wikipedia later recorded reports of a 2026 financing process and IPO preparation; those items remain press-reported.
Open weights
DeepSeek's public models share parameters (open weights) but do not necessarily share training data under an open license.1 Cloud providers including Microsoft Azure and Perplexity have hosted DeepSeek models.1 Independent researchers should distinguish weights, data, and evaluation claims when citing the company.
