## Questions

### How much does the Sync 3 API cost?

Sync's published list rate for Sync 3 is $0.134 per second of video (checked 2026-10-05). The provider account you connect bills you at the rate on that account, so a negotiated rate replaces the list rate. INFRO adds 0% to model spend.

### Which providers serve Sync 3?

In INFRO's provider registry, Sync 3 can be served by fal.ai and Sync. You connect your own account with any of them, and INFRO routes and fails over between the ones you connect.

### What is the Sync 3 model ID?

Request it from INFRO as "sync/sync-3". INFRO sends each provider its own id: fal.ai "fal-ai/sync-lipsync/v3", Sync "sync-3".

### How do I call Sync 3 through an OpenAI-compatible API?

Point an OpenAI SDK, or any HTTP client, at https://api.infro.io/v1 with an INFRO gateway key and send model "sync/sync-3" to POST /v1/videos. INFRO runs the request on a provider account you connected and returns the provider's response with an estimated cost.

### Does INFRO mark up Sync 3 usage?

No. Sync or the provider you connect bills model usage to your own account. INFRO charges a software subscription for routing, failover, observability, budgets and policy, and takes 0% of model spend.
