MiniMax H3
MiniMax H3 costs $0.072/sec on FairStack · a text to video model for 2K or 4K delivery from a single generation, Video that needs sound without a separate audio pass, Ultrawide 21:9 framing. No subscription required. Pay per generation with full REST API access. FairStack applies a transparent 20% margin on infrastructure cost so you always see the real price.
What is MiniMax H3?
MiniMax H3 is the frontier video model that H3 Max is a post-trained variant of. Audio is generated in the same pass as the picture, so dialogue, music and effects arrive already in sync. Where H3 Max trades resolution for speed and stops at 768P, base H3 adds 2K and 4K tiers (both upscale a 768P base result). Four tiers in all — 480p, 768p, 2K, 4K — across six aspect ratios including 21:9, at any duration from 5 to 15 seconds. Billing is per second of output and rises with the tier, at the model's cost plus a flat 20% platform fee, shown before you spend. Pick base H3 when you want 2K or 4K delivery from one generation; pick H3 Max when turnaround matters more than resolution.
