概要

このモデルについて

更新日: 2026年9月11日

Happy Horse 1.1 Image to Video animates a single start-frame image into a fluid, expressive video clip, at your choice of 720p or 1080p output resolution, with improved reliability over Happy Horse 1.0 via an automatic fallback provider path.

A single resolution parameter lets you draft cheaply at 720p and switch to 1080p for final output on the same endpoint.

よくある質問

FAQ

What is the cost of Happy Horse 1.1 Image to Video?

Happy Horse 1.1 Image to Video costs $0.14/sec at 720p (default) or $0.18/sec at 1080p on muapi. A 5-second 720p clip costs $0.70; the same clip at 1080p costs $0.90.

How is 1.1 different from Happy Horse 1.0?

1.1 is a newer generation with improved reliability (automatic fallback provider) and lower per-second pricing at both resolutions.

How do I choose the resolution?

Pass `resolution: "720p"` (default) or `resolution: "1080p"` in your request body — both are served by the same endpoint.

How many images can I provide?

Exactly one — `images_list` takes a single-element list, the start frame the video animates from.

What happened to the dedicated 720p/1080p endpoints?

They still work exactly as before, unchanged, for existing integrations. This unified endpoint is the new recommended way to access both resolutions through one integration.
