Output Schema
| Field | Type | Description |
|---|---|---|
id | string | Unique identifier for the generation task |
status | string | Task status: pending, running, completed, failed, timeout |
model | string | Model used for the generation |
outputs | array | Array of output items |

Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an
id - Poll — GET /v1/run/{id} until status is
completed,failed, ortimeout - Retrieve — Read
outputsfrom the completed response

AI Avatar Multi Text
AI Avatar Multi Text occupies the reference-led-video role in the model catalog for application builders. Its practical value is to separate this job from adjacent family routes: an upstream service can confirm that it has prompt, image, submit one well-scoped job, and receive a rendered video asset for downstream approval. This positioning explains when the exact sandbase-ai/ai-avatar-multi-text route belongs in an architecture without borrowing promises from another version, tier, or task variant.
A useful acceptance workflow begins by checking the request intent, asset eligibility, and downstream placement. The caller records required values separately from optional choices such as seed, voice1, voice2, resolution, first_text_input, second_text_input, runs a small representative sample, and stores the route name with the resulting artifact. Reviewers then compare that artifact with the agreed acceptance criteria, document any rejected setup, and promote only a successful request shape into larger batches. This workflow gives sandbase-ai/ai-avatar-multi-text measurable business context while leaving the Highlights section to explain model behavior.
Highlights
- Two written dialogue channels.
first_text_inputandsecond_text_inputprovide independent lines for the pictured participants. - Per-speaker voice selection.
voice1andvoice2assign distinct synthesized voices to the two text tracks. - Multi-person still-image animation. The required image establishes the participants and scene before their written dialogue is rendered.
- Resolution choice. The route exposes its declared resolution setting alongside dialogue and voice decisions.

When to Use
| Scenario | Why it fits |
|---|---|
| Choose AI Avatar Multi Text | Use it when the job specifically calls for ai avatar multi text and the route’s documented input contract matches assets already available in your workflow. |
| Keep the request reproducible | Use the required image, prompt explicitly, then record optional choices alongside the prompt for repeatable reruns. |
| Build controlled creative variations | Change one declared control at a time when comparing framing, format, duration, resolution, style, or other route-supported output decisions. |
| Integrate asynchronous delivery | Use this endpoint when an application can submit work, track completion, and collect the returned media URL instead of requiring an immediate inline artifact. |
| Validate before a large batch | Run representative prompts and source assets first, confirm the visual or audio behavior, then lock the successful request shape for scaled production. |
Prompt Guide
Lead with the subject or transformation, then add the composition, environment, style, lighting, motion, voice, or fidelity details relevant to this route. Keep every parameter inside the documented schema; the example below uses only fields declared for sandbase-ai/ai-avatar-multi-text.
