DeepSeek AI has rapidly gained attention as a powerful and cost-effective artificial intelligence model. However, there are several critical considerations to keep in mind before deciding to use this platform:
DeepSeek's data collection policies state that user information, including text or audio inputs, uploaded files, and chat histories, is stored on servers located in the People's Republic of China. This raises significant privacy issues, especially for users handling sensitive information, as the data could be subject to Chinese government access.
TIME.COM
The platform employs censorship mechanisms that restrict discussions on topics deemed politically sensitive by the Chinese government. For instance, inquiries about events like the 1989 Tiananmen Square massacre or issues related to Taiwan are either deflected or met with non-informative responses. This limitation can hinder open discourse and access to comprehensive information.
EN.WIKIPEDIA.ORG
Recent evaluations have revealed that DeepSeek's AI model, R1, failed to detect or block malicious prompts in security tests. Researchers from Cisco and the University of Pennsylvania conducted tests using prompts designed to elicit harmful content, achieving a 100% success rate in bypassing the system's safety measures.
