Recently, Kuaishou introduced the "AI Play Review" feature, which uses its self-developed large model "KeTu" to generate comment illustrations in short video comment sections. This provides users with a simple and quick entry point to AI drawing tools, adding interactive fun. The article also explores potential applications of AI in social media scenarios, including the creation of virtual characters and virtual assistants. However, it is important to note that the "AI Play Review" feature faces copyright ownership issues, and an independent AI painting product may be launched in the future. Kuaishou's innovative AI applications showcase the creativity of AIGC in user interaction and social patterns, promising to unlock greater practical value and creative potential.
