H3 Max Turbo is a speed-focused version of MiniMax H3. A five-second clip at 768p renders in roughly a second and a half, and the site states it costs about half as much as H3 Max while keeping similar prompt adherence.
You can start from a prompt or a starting frame, choose 480p or 768p, and create clips up to 15 seconds. It suits marketers who want to test many variations quickly.
