According to CoinMeta, DeepSeek just participated in the strategic placement of Yushu Technology with approximately 141 million yuan. Cui Tianyi, the person in charge of the Harness team, subsequently publicly criticized the description of IPO materials regarding DeepSeek, stating that it was exaggerated. The materials claimed that DeepSeek's performance ranked among the top tier in the world, with its programming ability only 0.3% behind that of Claude's flagship product. Cui Tianyi pointed out that there was only one benchmark test score in the v4 paper that was close to Opus's score of 4.6, which were 80.6 and 80.8 respectively, and that this could not be directly used to conclude that the overall programming ability was only 0.3% lower. He sarcastically said that such a writing style was hardly not "pure fabrication." However, his criticism was directed at the exaggerated statements in the intermediary materials, and not at denying DeepSeek's investment and cooperation with Yushu.
