Create an AI spokesperson avatar from a prompt or photo
Sume Avatar 1.0 creates a reusable avatar at a flat $0.95 from a text prompt, a photo, or props. How to make one before you generate talking videos.
Create the spokesperson once with POST /v1/avatar-1.0/generate, then reuse its avatar_handle for every ad. Avatar creation is a flat $0.95 per avatar (list prices from Sume's catalog rate card (GET /v1/catalog), confirmed in the repo's catalog file read 2026-10-03). The input is a prompt, a photo, or props, per Avatar.
Input types
The Jobs docs show the prompt form as {"avatar_handle":"studio_presenter","input":{"type":"prompt","prompt":"Friendly studio presenter"}}. The Avatar doc covers the props type as well.
| Input type | Use when |
|---|---|
| prompt | You want a new presenter from a description |
| photo | You have a source face image |
| props | You want items in the presenter's hands or frame |
Retry safely
Send an Idempotency-Key on the submit. Sume's jobs docs say to reuse the same key only for the same operation and payload, so a network retry does not create a second avatar. See Jobs and results.
Then generate
Once the avatar is ready, generate avatar video takes avatar_handle plus a script or video_inputs. Billing for those videos is per second, separate from the $0.95 creation fee.
