. It became the second of the group to list publicly when it floated in Hong Kong in January, following Z.AI1

1

. Competition among Chinese video-model developers has intensified since ByteDance released Seedance 2.0 earlier this year, drawing widespread attention for its ability to produce sophisticated clips from combinations of text, images, audio and video1
