Questions
HiDream-I1 Full, answered
- What is HiDream-I1 Full?
- HiDream-I1 Full is an image model from HiDream. A 17B open-weight image model with strong detail. 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 resolution and sizes does it make?
- 1:1, 3:4, 9:16, 4:3 or 16:9.
- How much does a run cost?
- An image costs $0.068. You see the exact price before you press go, and a run that fails costs nothing.
- Is HiDream-I1 Full free to try?
- No. There is no free credit: you add credit from $5, and your first top-up has no card fee. The cheapest run is $0.068 (an image), so $5 covers 73 of those. 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 hidream/hidream-i1-full, 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 HiDream account?
- No. Leap sends your request to HiDream's model and gives you what it makes. One Leap account runs HiDream-I1 Full and every other model, in the studio, through the API and from your agents.
Your idea, HiDream-I1 Full.
Every run shows its price before it starts, and one that fails costs nothing.

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. Agents can call it through the MCP server at app.tryleap.ai/api/mcp.
