What changed: TikTok integrated Symphony Agent, part of Symphony Creative Studio, with the Dreamina Seedance 2.5 AI model: video generation now supports up to 30 seconds, up from a previous 15-second maximum, and advertisers can upload up to 50 multimodal references (images, videos, audio), up from 9 previously, plus timestamp-specific creative direction. Symphony API now also includes Dreamina Seedance models, Symphony Agent, Trends Library, and video editing/extension tools. Starting November 9, advertisers outside North America can connect a BytePlus account within Symphony and purchase BytePlus tokens to access these models.
Who is affected
Businesses, agencies, and brands advertising via TikTok Ads Manager are affected; the BytePlus token purchase option applies to advertisers outside North America (the source excludes the United States).
What it means for your business
For businesses using TikTok advertising, this means longer and more detailed AI-generated product videos, and, outside North America, the option to buy extra BytePlus tokens to scale video production.
What to do
Log into Symphony with your TikTok Ads Manager account to try Symphony Agent and the expanded reference/duration features; if you're outside North America, consider connecting a BytePlus account and purchasing tokens as needed.
When it takes effect
BytePlus token purchasing started November 9; the other Symphony updates were announced on November 8, 2026.
