# deepseek

a sourced history of deepseek, the open-weights ai lab, its founder liang wenfeng, and high-flyer, the hedge fund behind it.

deepseek looks like it appeared in january 2025, when r1 took the top of the app store and ~$589b off nvidia in a day. it didn't — it is the research arm of high-flyer, a hangzhou quant fund that spent a decade building an ai trading firm and bought ~10,000 nvidia a100s before the export controls arrived. this is the record of the whale behind the lab: the classmates who automated trading from their dorms, the fund's peak and public apology, the fire-flyer clusters, the open-weights doctrine, the shock, the scrutiny, and the first raise that made the disruptor an incumbent.

  - [the lab](https://hraness.com/deepseek/history#lab): 2023–2024 — incorporation, the release ladder, grpo, the v2 price war, and v3's 2.788m-gpu-hour run.
