What is sync-3 Lipsync?

Is sync-3 Lipsync free to try?

Can I use what I make commercially?
Yes. You own what you make on Leap, so you can use it commercially, and we never train AI on it. The people and brands shown in a result can still have rights in it; the Terms say more.
Is there an API?
Yes. Leap's REST API runs it as sync/lipsync-3, at the same price per run as the studio, and agents can call it through Leap's MCP server. The request is at the bottom of this page.
Do I need a Sync Labs account?
No. Leap sends your request to Sync Labs' model and gives you what it makes. One Leap account runs sync-3 Lipsync and every other model, in the studio, through the API and from your agents.

The request

The same envelope for every model; only the model and its input change. With prefer: wait=60 the answer holds the result when the run finishes within a minute; a longer one is read again by its ID. A file input takes the ID that POST /v1/files returns for your upload. Agents can call it through the MCP server at app.tryleap.ai/api/mcp.
