With the rapid development of artificial intelligence technology, the application of AI-generated texts, images, and videos has matured across various fields. However, this has also been accompanied by a trust crisis, as the spread of misinformation poses a potential threat to society. To address this challenge, Tencent recently launched a brand new AI generated content detection tool aimed at 'countering fake AI' through AI technology. Developed by Tencent's Zhuque Laboratory, the tool consists of two systems: AI-generated text detection and AI-generated image detection.
