DeepSeek releases R1, an open-source reasoning model that shocks global markets
事件摘要
On January 20, 2025, Chinese AI lab DeepSeek released R1, an open-source reasoning model matching OpenAI's o1 on key benchmarks at a fraction of the training cost. Using Mixture-of-Experts architecture and Group Relative Policy Optimization, R1 achieved o1-level reasoning for approximately 1/20th of the training compute. On January 27, the release triggered a global stock market selloff that erased $593 billion from Nvidia's market cap — the largest single-day value loss in history — and DeepSeek became the most-downloaded free app on the US iOS App Store.
