MiniMax H3 Max
MiniMax H3 Max is a post-trained variant of MiniMax's H3 video model, tuned for stronger prompt adherence and aesthetics while running at higher throughput. It produces 480p or 768p native clips, plus a 1080p latent refinement of a 768p source, at 5–15 seconds with native stereo audio, text-to-video and image-to-video with optional first-to-last frame control, and six aspect ratios from 21:9 to 9:16. Ideal for cinematic storytelling and social content when you want H3 quality at a lower resolution and cost.

FAQ
How much does MiniMax H3 Max cost? Is it free?+
How does Layer's pricing work?+
There are no seat fees, feature gates, or plans on Layer. Instead, our platform uses a consumption based system with Creative Units (CUs) with a flexible monthly subscription. Every generation on Layer (image, video, 3D, or audio) consumes a Creative Unit, and you only pay for what you create.
