Perhaps no stock was more profoundly affected by the news from DeepSeek than Nvidia (NVDA -3.67%). In a sense, DeepSeek validated its dominance by announcing its H800 accelerators

Here’s what you need to know about DeepSeek, the Chinese AI startup that rattled markets as its app dethroned OpenAI's as the most-downloaded free app in the U.S. on Apple.

Some AI researchers hailed DeepSeek’s R1 as a breakthrough on the same level as DeepMind’s AlphaZero, a 2017 model that became superhuman at the board games Chess and Go by purely playing against itself and improving, rather than observing any human games.
