Ying He
Ying He is an artificial intelligence researcher at DeepSeek, the Hangzhou-based team behind the DeepSeek language models. They were among the authors of DeepSeek LLM in January 2024, DeepSeek-V2 in May 2024 and the DeepSeek-V3 Technical Report in December 2024, which presented a model with 671B total parameters. Their 2025 work included the DeepSeek-R1 paper, which Nature published in September 2025, and Insights into DeepSeek-V3, a May 2025 study of hardware-aware model co-design. They also co-authored DeepSeek-V3.2 in December 2025 and the DeepSeek-V4 preview in April 2026. In September 2026, they were among the authors of the DeepSeek-V4.1-Flash and DSec reports.
