What is DeepSeek? The $6M AI That Shook Silicon Valley in 2025

When a Chinese AI startup released a model that matched OpenAI’s performance at less than 6% of the training cost in January 2025, it sent shockwaves through the tech industry. Nvidia’s stock plummeted 18%, ChatGPT was dethroned from the App Store’s top spot, and AI leaders worldwide scrambled to understand one question: What is DeepSeek AI, and how did they pull this off?

What is DeepSeek? Quick Answer

DeepSeek is a Chinese artificial intelligence company that develops open-source large language models (LLMs) with performance comparable to GPT-4 and Claude, but at dramatically lower costs. Founded in July 2023 by Liang Wenfeng, DeepSeek AI gained global attention when their DeepSeek-R1 model topped app stores worldwide in January 2025, proving that frontier AI doesn’t require Silicon Valley-sized budgets.

The DeepSeek Company: Who Created DeepSeek?

DeepSeek (officially Hangzhou DeepSeek Artificial Intelligence Basic Technology Research Co., Ltd.) was created by Liang Wenfeng, who also co-founded the hedge fund High-Flyer that backs the venture. Unlike many AI startups chasing venture capital, the DeepSeek company operates with the analytical precision of a quantitative trading firm.

Who developed DeepSeek? A team of AI researchers and engineers based in Hangzhou, China, with backgrounds in quantitative finance and machine learning. Who is behind DeepSeek? The company is primarily funded by High-Flyer, giving it unique independence from traditional VC pressures.
