DeepSeek

DeepSeek is a Chinese artificial intelligence company that gained global attention by releasing high-performance large language models at a fraction of the cost typically associated with frontier AI development. Founded out of the quantitative trading firm High-Flyer, the company operates as an AI research lab focused on building and open-sourcing models competitive with leading Western systems.

DeepSeek drew widespread notice when its models demonstrated strong benchmark performance while reportedly requiring significantly less compute and training expenditure than comparable models from U.S. companies. This challenged prevailing assumptions about the hardware investment needed to reach the frontier, amplified debate over chip export controls, and rattled confidence in Silicon Valley's dominance of advanced AI.

In its first external funding round, DeepSeek raised approximately $7.4 billion at a valuation of around $50 billion, making it China's most valuable AI startup. The raise signals sustained investor confidence in DeepSeek's efficiency-focused approach and positions the company as a long-term rival to both U.S. AI labs and the cloud providers that distribute their models.
