ByteDance

The Chinese company behind TikTok, and the AI video tool Seedance.

ByteDance is the Chinese technology company best known as the owner of TikTok. It also operates a large artificial-intelligence effort, including generative tools for images and video.

Its Seedance video model has become a flashpoint in the entertainment industry: some Hollywood studios have sought to block it while quietly tolerating its use in practice. That tension captures a wider dilemma around AI-generated video, the technology is good enough to be genuinely useful, and controversial enough that companies are wary of admitting they rely on it.

ByteDance’s scale and consumer reach make it a significant player in how AI-generated media spreads to everyday audiences.
