Hailuo AI is MiniMax's browser-based video and image generator, currently centred on the MiniMax H3 family. The generator form exposes 2K output, 5-second clips, an Omni Reference field accepting up to 12 reference images and a 21:9 aspect ratio option. Official pages state that new users receive free credits on sign-up, and a homepage banner advertises 3,000 free credits for downloading the companion MiniMax Design app; Hailuo also runs a survey task that awards credits. No per-credit or per-second price list was retrievable from the official pages.

Official homepage states new users receive free credits and a banner advertises 3,000 free credits with the MiniMax Design download, but no USD value or per-credit rate is published, so no dollar figure is set (checked 2026-09-16).
