来源：information      （大白话就是DS看着质谱上市捞钱，他坐不住了。融资74亿）Up until two months ago, DeepSeek, the three-year-old Chinese AI lab, was an anomaly in the increasingly costly global AI battle. It had relied entirely on CEO Liang Wenfeng’s personal wealth and never raised outside money.       That changed in the middle of this month, when DeepSeek completed a $7.4 billion fundraising that valued the startup at more than $50 billion, the biggest ever first-time fundraising by a Chinese startup. The change of heart was prompted, say three people familiar with the CEO’s thinking, by Anthropic’s release in April of a preview of Mythos, a new model that the U.S. company said was so powerful that it can find and exploit software vulnerabilities, opening the door to potential chaos and misuse.    After seeing how Mythos achieved strong capabilities from training on enormous amounts of compute and data, Liang realized DeepSeek couldn’t compete without a massive warchest. Now the firm, which currently has a staff of around 300, is expanding both its workforce and its computing capacity.       In a rare public announcement, DeepSeek on Thursday said it is planning to “at least double” the headcount in all of its departments, including AI system development, infrastructure, product development and deep learning research. The DeepSeek Harness team, which works on transforming DeepSeek AI models into autonomous AI agents, is interviewing candidates every day, team leader Tianyi Cui, who joined the company from Jane Street in March, said on X earlier this month.        The company is also intensifying its efforts to adapt to Huawei chips, in light of U.S. export controls, while continuing to train its models on Nvidia chips stockpiled via the black market.
