DeepSeek, a Chinese AI startup, has made headlines with its R1 model, causing significant interest. The company claims to have developed an efficient, low-cost AI rivaling leading models, prompting investors to question US tech giants’ spending. However, DeepSeek’s transparency, self-censorship, and China-only registration restrictions have surfaced as key challenges.
The company was eventually forced to limit signups to those with mainland China telephone numbers — but claimed the move was the result of “large-scale malicious attacks” on its services. The startup’s work “illustrates how new models can be created” using a technique known as test time scaling, the company said.
