About Hunyuan Motion

Published model facts and visible product behavior, without speed, quality, or production-readiness promises.

Fast and Standard models

Choose the 0.46B Fast model for lower-cost exploration or the 1B Standard model for a more expensive comparison pass.

Published action coverage

The HY-Motion 1.0 paper reports more than 200 motion categories across six major classes.

FBX and JSON downloads

Preview and download available outputs, then validate skeleton mapping, scale, axes, timing, and root motion in your own toolchain.

Clear model limits

The official model guidance focuses on one humanoid action in English and does not claim support for multi-person interaction, camera direction, non-humanoids, or seamless loops.

A safer three-step evaluation

Test one concrete action, compare models only when useful, and validate every downloaded file.

  1. Write one focused action — Use an English prompt under 60 words with one humanoid, an ordered movement, direction, tempo, and a clear ending pose.
  2. Start with the lower-cost pass — Use Fast to check whether the action is readable. Spend more on Standard only when the first result justifies a controlled comparison.
  3. Validate outside the browser — Preview the result, download FBX or JSON, and test retargeting, scale, axes, root motion, contacts, and cleanup time before adopting it.
