TikTok integrates ByteDance Seedance 2.0 AI video model into Symphony ad suite

TikTok integrated ByteDance's Dreamina Seedance 2.0 AI video model into its Symphony Creative Studio ad suite, available to all paid advertisers globally. The model generates branded video with synchronized audio in a single pass from text, image, or reference-video inputs, improving product consistency across video segments and producing more natural motion. Every output includes AI labels, invisible watermarking, and C2PA Content Credentials by default. Symphony compresses ad creation timelines from weeks to hours. This positions TikTok to compete directly with Meta's AI ad tools and represents a significant step in automated creative production at scale. Seedance 2.0 was previously benchmarked as competitive with OpenAI Sora.
