TikTok Symphony Agent: the same flow through one Sume API run

Symphony Agent, announced June 22 2026, lets an advertiser upload a product image, pick a TikTok trend or a custom reference video, and walk through a brief, an insight report, a storyboard and a final video. On Sume the reference-to-video part is one run of the sume-recreate Format, called with a product image and a pasted reference.

Symphony facts are from TikTok's Symphony Agent post, read 2026-09-30. Sume facts are from the Format catalog and Create a run.

How does Symphony Agent work, per TikTok?

A prompt box on the home page takes a product image and a trend (a template, a top ad trend, or a custom reference video). The workflow creates a product brief, an insight report (for top ad trends or uploaded references), a storyboard and the video, and you can give feedback in the prompt box at each step.

What does sume-recreate do?

The Format's instruction says to recreate the structure of a pasted TikTok or Instagram URL or an attached clip: keep its scene order, beat timing, caption rhythm and music-or-voice choice, cast a new presenter, and generate every still, clip, audio track and caption from scratch. It is one of the callable catalog slugs at the sume handle.

How do I call it?

POST /v1/formats/sume/sume-recreate/runs with a key that carries formats:write, an Idempotency-Key header, your instruction and attachments. The catalog Format stays shared; the run and its spend belong to your key. You can bound spend with generation_spend_cap_usd, up to the platform maximum of $500.

Is it the same output as Symphony Agent?
