What this site does
We explain Utopai X — the video model Utopai Studios launched inside its PAI platform on September 30, 2026 — and we host the closest publicly available base to it: MiniMax H3, the model Utopai X is post-trained on.
The studio on this site turns text prompts, first and last frames, and reference media into 2K clips of 5–15 seconds. New accounts receive welcome credits, so a first clip needs no subscription.
The model behind it
MiniMax H3 is an open video generation model. It accepts text, up to nine reference images, three video clips and three audio clips, and renders at 2K in six aspect ratios. Utopai Studios announced Utopai X as post-trained on MiniMax H3, which is why it powers this site.
