In January 2025, Chinese company DeepSeek caused shock in technology world. DeepSeek-R1 model showed results comparable to GPT-4 and Claude, but spent $6 million on development versus OpenAI's $500 million. Within days, the app became most downloaded in American App Store, surpassing ChatGPT.

On January 27, NVIDIA shares fell 17%, losing nearly $600 billion in market cap—largest single-day loss in American stock market history. Many call DeepSeek's release a "Sputnik moment," undermining confidence in US technological superiority.

In this guide, we'll break down what DeepSeek is, how Chinese startup achieved such results with limited access to advanced chips, whether it's safe to use the model, and what this means for global AI competition.

What Is DeepSeek

DeepSeek is Chinese artificial intelligence development company founded in late 2023. Company creates open large language models for natural language processing, code generation and mathematical reasoning. In short time, DeepSeek transformed from unknown startup to serious player on global AI arena.

Flagship model DeepSeek-R1 uses Mixture-of-Experts architecture with 671 billion parameters. This architecture allows model to activate only necessary parts when responding to query, saving computational resources. Tests show DeepSeek-R1 surpasses Llama 3.1 and Qwen 2.5, while being comparable to GPT-4o and Claude 3.5 Sonnet.

Key DeepSeek Features:

  • Fully open source—available for free use

  • Publication of detailed methodology for all research

  • Development cost $6M vs $500M for competitors

  • Mixture-of-Experts architecture for efficient resource use

  • Support for 338 programming languages in Coder-V2 version

  • Context window up to 128,000 tokens for large inputs

Who's Behind DeepSeek

DeepSeek founded in 2023 by Liang Wenfeng—Chinese entrepreneur and mathematical prodigy born in 1985 in Guangdong province. Before launching DeepSeek, he created High-Flyer, a hedge fund that now finances company. By end of 2017, most of High-Flyer's trading operations managed by AI systems.

Foreseeing AI's importance, Liang began accumulating NVIDIA GPUs in 2021—before US government imposed restrictions on chip sales to China. This allowed gathering about 10,000 NVIDIA A100 GPUs, laying hardware foundation. First breakthrough came in May 2024 with DeepSeek-V2 release, which launched price war among Chinese tech giants.

Key DeepSeek Development Milestones:

  • February 2016: Liang Wenfeng founded High-Flyer hedge fund

  • 2021: Started accumulating NVIDIA A100 GPUs (about 10,000 units)

  • July 2023: Official registration of DeepSeek as separate company

  • May 2024: DeepSeek-V2 release, launching price war in China

  • December 2024: DeepSeek-V3 release with 671B parameters

  • January 2025: DeepSeek-R1 release, entering international market
