DeepSeek — Headcount: 150

NoteThe source directly states that DeepSeek's V3 technical report is attributed to 'a team of 150 Chinese researchers and engineers.' This matches the claimed exact stored value of 150 employees as of mid-2024. The source article is dated January 2025 but references the V3 model released December 26, 2024, and discusses the team composition at that time. The claim specifies 'as of 2024-06' (June 2024), while the source discusses the team in late 2024/early 2025. However, the source explicitly confirms the 150-person figure for the core research team. The additional context about flat hierarchy and collaboration is consistent with the source's description of the company's approach. The 31-person data automation team is separate from the 150 core researchers, so the 150 figure is confirmed.
