DeepSeek

DeepSeek, also known as 深度求索, is an AI platform headquartered in China. It provides access to its artificial intelligence models through an API and a web-based interface. Users can leverage these models for various generative AI tasks.

The platform has experienced rapid growth in popularity, which contributed to its visibility before the 2025 incident. Its headquarters in China places it within the country's technology sector. The rapid growth suggests an expanding user base, though exact numbers are not provided.

DeepSeek specializes in generative AI services that can be integrated into applications via its API. The January 2025 incident revealed its susceptibility to large-scale distributed denial-of-service attacks targeting both API and web infrastructure. Additionally, the attack highlighted risks of model manipulation that could produce harmful outputs such as ransomware code and toxic content instructions, raising concerns about data exposure and the security of platform integrations.

Information about DeepSeek’s ownership, parent company, or subsidiary relationships is not explicitly provided in the available sources. Consequently, any details about its corporate structure remain unspecified based on the current material.

On January 3, 2025, a cyberattack forced the temporary suspension of new user registrations on DeepSeek’s service. The attack was attributed to a massive DDoS effort that overwhelmed its API and web systems, underscoring broader security challenges faced by widely adopted AI technologies amid their expanding adoption.
