## 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:
- Payments & pricing, 30 against 20
- Transparency & trust, 72 against 53

Also in its favour:
- Runs on your own machine
- No incidents deducted, where Runway API loses 3 points for them

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

### Runway API (C)

Good for: Agents that want one key for Runway's own editing models (Aleph 2.0, Act-Two) and a menu of third-party models with one billing system.

Ahead on:
- Schema & documentation, 93 against 86
- Security & auth, 51 against 41
- Maintenance & community, 62 against 48

Watch for: Gen-3 Alpha Turbo and Gen-4 Aleph were removed on 2026-07-30 with no prior notice in the changelog

## 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.

**Runway API.** OpenAPI 3.1, llms.txt and Markdown copies of every docs page. Gen-3 Alpha Turbo and Gen-4 Aleph were removed on 2026-07-30 with no prior notice in the changelog.

## 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

### Runway API

1. Send `X-Runway-Version: 2024-11-06` on every request or it fails
2. Use the SDK's wait-for-output helper or poll GET /v1/tasks/{id} until SUCCEEDED or FAILED
3. Don't retry a SAFETY.* failure unchanged. It's moderation, not an outage
4. Take model IDs from the models page, not memory. Two were removed without notice on 2026-07-30
5. Copy outputs to your own storage. URLs expire within 24 to 48 hours
