MiniMax H3
MiniMax H3 is an audio-video generation system that can combine text, images, video, and audio references to produce short video clips with synchronized stereo sound.
MiniMax has released the H3-Base weights, code, example assets, and local deployment guidance for 768p output. Its hybrid 2K workflow combines a local H3-Base deployment with two hosted MiniMax components, while the direct MiniMax API offers a separate fully hosted route at 768P or 2K. Use this as a first read, not a recommendation. Open the original project before trusting details like terms, limits, privacy, cost, setup, or safety.
What it is
One model for video and stereo audio
H3-Base jointly generates video and audio instead of adding a separate soundtrack afterward. It supports text-to-video, first-and-last-frame control, and reference-driven generation from images, video, and audio.
Why it stands out
Mixed references shape the same clip
The reference workflow can combine up to nine images, three video clips, and three audio clips within the documented limits. That lets a creator carry a subject, motion, camera move, visual style, or voice into one generated result.
Availability
Local, hybrid, and hosted routes
The official repository includes public H3-Base weights, SGLang examples, Diffusers support, and ComfyUI workflows for local 768p generation. A hybrid 2K workflow combines local H3-Base with hosted Context-IR and Regenerate-2K APIs, while MiniMax also offers direct hosted generation at 768P or 2K.
Why it matters
What makes it useful
Creative video workflows often split prompting, reference handling, motion, dialogue, sound effects, and music across several tools. H3 brings those inputs and outputs into one generation system, so creators can test whether a voice, movement, subject, and scene direction stay connected inside the same short clip.
What to know
Where it fits
Open it when comparing short-form video models that use more than a text prompt. It is especially relevant for text-to-video, image animation, first-and-last-frame control, reference-based character or style work, and clips where generated sound is part of the scene.
Notable points
What stands out
This is a new release, and its performance claims and example outputs are MiniMax-published materials. The public H3-Base release covers local 768p generation. Reproducing MiniMax's documented 2K pipeline with a local base deployment still requires its hosted Context-IR and Regenerate-2K APIs; direct API generation is a separate fully hosted route.
Before using
What to review
Read the MiniMax H3 Community License before downloading or deploying the weights. Its defined Applicable Territory excludes the European Union, United Kingdom, Republic of Korea, and United States, and the agreement restricts using, displaying, or distributing the model works and their outputs or results outside that territory.
Choose between local H3-Base, the hybrid 2K workflow, or the direct MiniMax API. The official SGLang examples use four GPUs; ComfyUI offers separate text-to-video, image-to-video, and reference-to-video workflows that use pruned INT8 diffusion-model files and an NVFP4-AWQ text encoder.
Expect a capability difference between the public base model and the documented hybrid 2K workflow: 2K regeneration and MiniMax's Context-IR processing are not included in the current public release.
Check the current API price, account, moderation, data-handling, and regional availability terms before sending private or rights-sensitive reference media to a hosted service.
Confirm that you have permission to use the people, voices, music, brands, images, and video supplied as references, and label generated public media where the applicable terms or local rules require it.
Reader fit
Who may find it relevant
Creators and builders testing short video with synchronized dialogue, effects, ambience, or music.
Technical users comparing text-to-video, frame-guided video, and mixed-reference generation in one model family.
Teams deciding among local 768p control, a hybrid 2K pipeline, and direct hosted generation.
Less relevant for readers seeking a simple lightweight editor, long-form video generation, or a permissively licensed model available for unrestricted use in every region.
Editorial note
Why LifeHubber lists it
LifeHubber lists MiniMax H3 because its public base weights can generate video and stereo audio from mixed references, while the higher-resolution routes make the service dependency visible. Readers can compare local 768p control, a hybrid 2K workflow, direct hosted generation, hardware demands, and license limits before choosing a path.

Before relying on this entry
LifeHubber lists entries to help readers inspect AI projects, not to endorse them or prove they are safe, suitable, accurate, maintained, or right for a specific use. We do not verify every entry in depth. Before relying on anything listed, review the original materials, terms, privacy practices, limits, and risks that matter for your situation.
What to explore next
Compare short audio-video clips with longer dance generation.
MiniMax H3 combines mixed references and generated stereo audio in clips up to 15 seconds. Wan-Dancer shifts the question toward carrying music and choreography across a longer performance.
