The emergence of a small Chinese artificial intelligence (AI) company called DeepSeek initially put a giant hole in the U.S. stock market. Tech stocks -- particularly those connected to the AI trend -- got crushed,

DeepSeek stunned the tech world with the release of its R1 "reasoning" model, matching or exceeding OpenAI's reasoning model for a fraction of the cost.

DeepSeek has launched an AI model that was reportedly developed with significantly less computational power than traditional methods. Shares of Nvidia are under pressure amid concerns that DeepSeek's methods may undermine demand for its high-performance GPUs.

One of the biggest stories from last week underscores just how critical AI has become—not just for Silicon Valley, but for America’s national security.

The chip maker's shares were falling with the wider market after the U.S. president said he intends to impose levies on imported semiconductors.

Chinese startup DeepSeek said it trained its AI model for less than $6 million, compared to the billions of dollars U.S. tech companies are spending. Nvidia stock plummeted in one trading session on concern that certain customers may opt for cheaper AI chips.
