TikTok Symphony Avatar virtual try-on: two Sume Formats

TikTok's July 28 2026 product preview says the upgraded Symphony Avatar "brings voiceover, product demos, and virtual try-on into one workflow". On Sume there is no single avatar tool for all three; two catalog Formats cover the visual parts, sume-virtual-try-on and sume-product-usage-demo.

TikTok's text is from its Q3 product preview, read 2026-09-30. Format names are from the Format catalog.

What did TikTok announce for Symphony Avatar?

In Symphony Creative Studio, the upgrade is for more expressive, on-brand UGC-style content that narrates, demonstrates and showcases products with less production lift, without new shoots or reshoots. The snapshot does not list supported garment types or markets.

Which Sume Formats map to it?

Both slugs are on the catalog's callable list. The try-on recipe starts from a garment still and creates a 9:16 video of a creator changing into the garment, preserving the same face, body, room and camera angle. The usage demo recipe creates a 9:16 casual product-usage demo from a packshot.

What do I send?

Read the Format first with GET /v1/formats/sume/{slug}; its io profile says what input shape it expects, for example url_to_video. Then call POST /v1/formats/sume/{slug}/runs with the garment or packshot as an image attachment and your instruction. Try-on output depends on the garment and reference photos you provide, so review each result before it goes into an ad.

Where is a Shopify version of this?
