MiniMax's new open general-purpose multimodal video model, Hailuo H3, is now live on HopBase through an official direct connection. Sign up and start calling it self-serve. The cover of this post is the untouched first frame of a real H3 output (2K text-to-video).
What it does
- Three workflows: text-to-video, image-to-video (first / last frame anchoring), and multimodal reference — images, video clips and audio jointly steer subject, motion and rhythm.
- 4-15 second clips at 768P or 2K, aspect ratios from 21:9 to 9:16, 24 FPS.
- Native stereo audio on every clip, with in-model dialogue and voice-over via TTS covering 11 languages — no separate dubbing pass.
- Billed only on completed clips: failed or safety-filtered generations are never charged.
Pricing: 85% of official list
