Cui Tianyi: DeepSeek IPO materials exaggerate the description of programming abilities

DeepSeek participated in the strategic placement of Yushu Technology for approximately 141 million yuan, and the head of Harness, Cui Tianyi, publicly questioned the description of DeepSeek V4's programming capabilities in the relevant IPO materials. The material states that DeepSeek V4's programming ability is only 0.3% weaker than Claude's flagship. Cui Tianyi pointed out that in the V4 paper, only the SWE Verified score is close to Opus 4.6, which cannot be summarized as an overall programming ability gap. He also claimed that this writing style is exaggerated.
