MiniMax H3Open Weights
Multimodal AI Video with Native Stereo Audio

MiniMax H3 is a general-purpose multimodal AI video generation model from MiniMax. It understands text, images, video, and audio in one context and can generate clips up to 15 seconds at 2K resolution with synchronized native stereo audio.

MiniMax H3 is the official model name. Some users search for Hailuo 3.0 or Hailuo H3 because Hailuo is MiniMax's consumer video product, but MiniMax's launch post and official model repository call the model MiniMax H3.

MiniMax publishes the complete H3-Base weights and describes the release as open source. More precisely, H3 is an open-weight model distributed under the MiniMax H3 Community License rather than a standard permissive license such as Apache 2.0 or MIT. Review the current license before commercial deployment or redistribution.

The official MiniMaxAI MiniMax-H3 repository on Hugging Face provides the model index and FL2VA and Ref2VA checkpoints. MiniMax also documents inference through Diffusers, SGLang, vLLM, and ComfyUI. The model files are large, so local deployment requires substantial compatible hardware.

The official local H3-Base workflow validates 768p output. MiniMax's full 2K workflow combines a locally deployed H3-Base service with official H3-Context-IR and H3-Regenerate-2K API stages. Fully local H3-Base and the complete API-backed 2K workflow are therefore not identical.

Yes. H3 jointly predicts video and audio and decodes native stereo sound, including voice, ambience, effects, and music. MiniMax designed these audio types to be modeled together instead of splitting them into separate generation systems.

H3 supports text instructions plus reference images, videos, and audio. Official checkpoints cover text-to-audio-video, first-or-last-frame-to-audio-video, and reference-to-audio-video workflows, while the broader system supports multimodal reference and editing relationships expressed in natural language.

Describe the subject, action, camera movement, shot sequence, lighting, visual style, dialogue, ambience, sound effects, music, and the role of every reference. H3 is designed to understand relationships among inputs, so explain what to borrow from each image, video, or audio asset.

Yes. MiniMax H3 is available through VisionStory’s AI video tools, alongside the other cinematic video models. MiniMax built H3 — VisionStory provides the workflow around it, not the model itself.

MiniMax H3, ByteDance Seedance, and Kuaishou Kling are multimodal video models with overlapping text-to-video and image-to-video capabilities. H3 is especially differentiated by its released H3-Base weights, generalized reference-and-editing design, 2K pipeline, and native stereo audio. The best choice depends on the desired motion, reference control, audio workflow, deployment needs, and current product availability.
