Synthesized from 4 Yomimono stories · updated Oct 9

MiniMax H3 arrived as an announced model from Chinese AI firm MiniMax, generating up to 15 seconds of audio-synced video from text, images, or voice at 768p or 2K resolution, with support for multiple simultaneous media inputs. In a blind test by Artificial Analysis, it ranked second for text-to-video, behind Gemini Omni Flash and ahead of Seedance 2.0. It was available via API at announcement, with open weights planned.

By August 9, MiniMax had released H3 as an open video generation model that matched ByteDance's Seedance 2.0 in cloud performance. Its Omni Reference feature accepts up to nine images, three videos, and three audio tracks, and it runs on a local PC with an RTX 4090. ASCII.jp tested it with live-action and anime-style prompts.

On the cloud side, fal developed MiniMax H3 Max, which generates 15-second videos in about 13 seconds while maintaining quality. That service offers 5-second videos free up to five times daily, supports Japanese prompts, and costs $0.08 per second at 768p, with a 50% off sale until September 1.

The fastest local results came from a single RTX 5090 running H3, where a 5-second image-to-video clip dropped from 193.5 seconds to 31.6 seconds over 41 days. That 6.12x gain used a 20-step baseline, the official Turbo 8-step LoRA, Hao AI Lab's FastH3 4-step, a community-converted TaoMate 3-step LoRA, INT8 attention, and sparse attention. H3 Max weights have not been released 28 days after fal said on X that it would publish them.
