DeepSeek has just participated in a strategic placement of YuTree Technology with approximately 141 million yuan. The head of the Harness team, Cui Tianyi, subsequently publicly criticized the description of DeepSeek in the related IPO materials. The materials claim that DeepSeek V4 "ranks among the top tier globally in performance, with programming capability only 0.3% weaker than Claude flagship." Cui Tianyi pointed out that in the V4 paper, only one SWE Verified score is close to Opus 4.6, with scores of 80.6 and 80.8 respectively, which cannot be directly generalized to mean that the overall programming capability is only 0.3% weaker. He sarcastically stated that such writing is hard not to be considered "pure fabrication." However, the criticism was aimed at the exaggerated statements in the intermediary materials.
