Questions

Lucy Edit Pro, answered

What is Lucy Edit Pro?
Lucy Edit Pro is a video editing model from Decart. Changes one thing in a video from a prompt (an outfit, an object, a product, the background) and keeps the rest as filmed. It is new on Leap and in preview: it works, and it may still change. On Leap it runs in one studio beside every other top model, with one account.
What do I give Lucy Edit Pro?
Lucy Edit Pro starts from words or a video.
How is it different from Lucy Restyle?
Lucy Edit Pro: Changes one thing in a video from a prompt (an outfit, an object, a product, the background) and keeps the rest as filmed. Lucy Restyle: Redraws a whole video in the style you describe while the motion stays as filmed, at a cent a second. They all run in the same studio, so you can try one prompt on each.
How much does a run cost?
It costs $0.20 a second of your video. You see the exact price before you press go, and a run that fails costs nothing.
Is Lucy Edit Pro free to try?
No. There is no free credit: you add credit from $5, and your first top-up has no card fee. It costs $0.20 a second of your video. You pay per run, in dollars, with no subscription.
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 decart/lucy-edit-pro, 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 Decart account?
No. Leap sends your request to Decart's model and gives you what it makes. One Leap account runs Lucy Edit Pro and every other model, in the studio, through the API and from your agents.

Your idea, Lucy Edit Pro.

Every run shows its price before it starts, and one that fails costs nothing.

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.
