## Which one, for what

### Replicate video models (B)

Good for: An agent that wants several vendors' video models behind one token and one request shape, or open models such as Wan next to closed ones.

Ahead on:
- Reliability, 75 against 36
- Schema & documentation, 86 against 61
- Payments & pricing, 30 against 20
- Transparency & trust, 72 against 63

Also in its favour:
- Runs on your own machine

Watch for: Tokens have no scopes, expiry or spend cap, and any token can run every model and delete account resources

### Seedance on BytePlus ModelArk (C)

Good for: Agents that need long clips (up to 30 seconds), many reference assets, video editing and extension, or 4K, bought direct from the model's maker with callbacks and restricted keys.

Ahead on:
- Agent ergonomics, 85 against 72
- Security & auth, 79 against 41
- Maintenance & community, 75 against 48

Watch for: No status page was found on byteplus.com, the docs or the trust centre, and no SLA was found that names ModelArk inference

## Verdicts

**Replicate video models.** One bearer token reaches more than twenty official video models at published per-second prices, each with a typed input schema, and failed runs aren't charged. Tokens have no scopes or spend cap, no SLA is published, and the terms let Replicate withdraw any model without notice.

**Seedance on BytePlus ModelArk.** The video task API documents limits, error codes and per-model parameters in detail, with callbacks, a filterable task list and API keys restrictable by model and IP address. No status page, OpenAPI file or free video quota was found, the newest models need a USD 30 balance, and BytePlus model services are not sold in the United States.

## Before you call either

### Replicate video models

1. Call official models at `POST /v1/models/{owner}/{name}/predictions` with no version, then poll `GET /v1/predictions/{id}` or pass `webhook`. Video jobs usually outlast the 60-second `Prefer: wait` window
2. Download the output file within the hour. API predictions lose inputs, outputs and logs after 60 minutes
3. Read the model's price tiers before setting `resolution`, `mode` or `generate_audio`. Kling 3.0 runs from $0.168 to $0.42 a second and Veo 3.1 doubles with audio
4. Send `Cancel-After` on every create. There is no idempotency key, so a blind retry is a second paid video
5. Keep credit above $20 or enable auto-reload. Low balances are throttled, and granted credit with no card is held to 6 requests a minute

### Seedance on BytePlus ModelArk

1. POST to `/api/v3/contents/generations/tasks` on ark.ap-southeast.bytepluses.com, then poll GET `/contents/generations/tasks/{id}` or pass `callback_url`. Callbacks need an answer within 5 seconds
2. Download the result at once. Video URLs last 24 hours, task records 7 days, and a Seedance 2.5 URL allows 100 downloads
3. Pass `resolution`, `ratio` and `duration` in the request body. Parameters appended to the prompt as `--rs` or `--dur` are weakly validated and may be ignored
4. On Seedance 2.5 set `omni_reference_task_type` to `edit` or `extend` so constraint errors arrive at submission. With `auto` they arrive after the task leaves the queue
5. Do not send reference images or video with real human faces to Seedance 2.5 or 2.0. Only a queued task can be cancelled with DELETE
