Researcher

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.

Timeline

  1. January 2024

    The DeepSeek LLM paper

    In January 2024, they are among the authors of DeepSeek LLM: Scaling Open-Source Language Models with Longtermism, a study of scaling laws for open-source language models in 7B and 67B configurations.

  2. May 2024

    The DeepSeek-V2 model

    In May 2024, they are among the authors of DeepSeek-V2, a Mixture-of-Experts language model with 236B total parameters, 21B of them activated for each token, and a context length of 128K tokens.

  3. December 2024

    The DeepSeek-V3 report

    In December 2024, they are among the authors of the DeepSeek-V3 Technical Report, which presents a Mixture-of-Experts model with 671B total parameters and 37B activated for each token.

  4. January 2025–September 2025

    DeepSeek-R1 in Nature

    They are among the authors of DeepSeek-R1, posted on arXiv in January 2025 as a study of incentivizing reasoning in LLMs via reinforcement learning. Nature publishes the paper in September 2025 with the DeepSeek-AI Team in Hangzhou, China.

  5. May 2025

    Insights into DeepSeek-V3

    In May 2025, they co-author Insights into DeepSeek-V3: Scaling Challenges and Reflections on Hardware for AI Architectures. The paper uses DeepSeek-V3, trained on 2,048 NVIDIA H800 GPUs, to show how hardware-aware model co-design enables cost-efficient training and inference.

  6. December 2025

    DeepSeek-V3.2 with sparse attention

    In December 2025, they are among the authors of DeepSeek-V3.2, which introduces DeepSeek Sparse Attention (DSA), an attention mechanism that reduces computational complexity in long-context scenarios.

  7. April 2026

    DeepSeek-V4 preview models

    In April 2026, they are among the authors of the DeepSeek-V4 preview: DeepSeek-V4-Pro with 1.6T parameters and DeepSeek-V4-Flash with 284B parameters, both supporting a context length of one million tokens.

  8. As of October 2026

    Researcher at DeepSeek

    They are an artificial intelligence researcher at DeepSeek. In September 2026, they are among the authors of the DeepSeek-V4.1-Flash report on KV cache compression and of the DeepSeek Elastic Compute (DSec) report on a sandbox platform for agentic training.
