TikTok has built Seedance 2.0, ByteDance's video generator, into Symphony, the suite of generative tools it offers brands for advertising content. Symphony launched in 2024 and has gained features steadily since.
ByteDance pitches the model as producing polished clips with synced sound and more natural camera moves than earlier generators, and tells advertisers it has been tested against brand-safety standards.
The integration arrives as OpenAI's Sora falters, and marks a faster push of AI video into TikTok's ad business after a cautious start.
