Chinese AI startup DeepSec has temporarily restricted new user registrations after facing cyberattacks triggered by its sudden rise to fame. The company, which recently launched a low-cost AI assistant, had previously suffered a website shutdown when its application became the top-rated free app on Apple’s US App Store.
According to DeepSec’s status page, the company has since resolved issues with its API and website logins. However, Monday’s **extended outage—the longest in nearly 90 days—**coincided with a surge in its popularity.
DeepSec’s AI Model Disrupts the Market
Last week, DeepSec introduced a free AI assistant that operates with lower data usage and significantly reduced costs, making it a game-changer in the AI industry. The DeepSec-V3 model, described by its creators as a leading open-source AI that rivals top closed-source models, has gained significant traction among US users since its January 10 release, according to data from Sensor Tower.
DeepSec’s rise has challenged long-standing perceptions of American dominance in artificial intelligence, especially amid Washington’s export controls aimed at restricting China’s access to advanced AI chips.
Stock Market Reaction: US Tech Giants Take a Hit
The Nasdaq tumbled 2.7% on Monday, as global investors reacted to the emergence of DeepSec’s cost-effective AI model. Major US tech players—**Meta, Microsoft, and Alphabet (Google’s parent company)—**all saw their shares decline.
One of the most significant impacts was felt by Nvidia, whose stock plunged over 11%, erasing nearly $400 billion in market value. This signals growing concerns about competition from DeepSec, which has managed to develop a highly competitive AI model with just $5.6 million in investment—a fraction of the billions spent by American AI firms.
China’s AI Challenge: A ‘Sputnik Moment’ for the US?
Kathleen Brooks, Research Director at XTB, notes that China is increasingly challenging US technological supremacy. The question now is whether China can develop AI faster, cheaper, and more efficiently than its American counterparts—and potentially win the AI race.
As leading US tech firms Meta and Microsoft prepare to release earnings reports this week, analysts expect them to address DeepSec’s disruptive entry into the market. Venture capitalist Marc Andreessen compared DeepSec’s rise to the “Sputnik moment”—recalling the Soviet Union’s 1957 launch of a satellite, which stunned Washington and accelerated the space race.
DeepSec’s Future and Global AI Competition
DeepSec’s unexpected success has shaken the AI landscape and posed a direct challenge to Silicon Valley. With its AI assistant now ranked as the top free app on Apple’s US App Store, the company has proven that China is no longer just following in AI innovation—it’s now leading the charge.
As the global AI arms race intensifies, DeepSec’s next moves will be closely watched—not just by the tech industry, but by investors, policymakers, and AI researchers worldwide.
