One Model.Every Signal.
MiniMax H3 brings text, image, video, and audio references into one creative context. This guide turns the launch into a practical workflow—without the hype.

From separate inputs to one direction.
Unified multimodal understanding
H3 is announced as reading text, images, video, and audio as one shared context—useful when a creative brief depends on identity, motion, sound, and direction at the same time.
Video with native sound
The launch describes clips up to 15 seconds at 2K with stereo audio generated as part of the same result. Provider-specific settings may differ.
Reference-led direction
Use references as roles: an image for a subject, a video for motion, an audio clip for voice, and text for the final instruction. Clear role assignment reduces ambiguity.
In-context regeneration
MiniMax presents H3 as supporting generation and targeted editing within one model. For practical work, state both the requested change and the elements that must stay stable.

Direct the outcome, not just the frame.
Brand films
Coordinate product appearance, typography, camera movement, music, and voice around one campaign direction.
Product stories
Use image references for product identity and explicit shot timing for reveals, demonstrations, and transitions.
Motion transfer
Describe how movement from a video reference should be applied, then name the subject and background elements that should remain consistent.
UI & game concepts
Prototype interface motion, world transitions, VFX beats, and audiovisual pacing before committing to a full production pipeline.
03 / Workflow
Brief like a director.
H3’s value is not “more inputs.” It is the ability to give each input a job, then describe how those signals should meet in the final shot.
Define the invariant
Name the identity, product, logo, palette, or spatial relationship that cannot drift between frames.
Assign every reference
State what to borrow from each image, video, or audio file. Avoid leaving the relationship between references implicit.
Block the shot in time
Write the opening, middle beat, and ending. Include camera movement, subject action, transition, and sound cues in sequence.
Revise one variable
When iterating, identify one intended change and repeat the preservation constraints. This makes edits easier to evaluate.
04 / Prompt blueprint
Build the shot.
Use this production-neutral structure as a starting point. Replace the bracketed fields and adapt the wording to the interface or API provider you are using.
Best practice: say what changes, what moves, what sounds, and what must remain unchanged.
SUBJECT: [identity, clothing, product details] ACTION: [one clear physical action] ENVIRONMENT: [location, lighting, weather, atmosphere] CAMERA: [shot size, lens feel, movement] TIMING: [opening → middle beat → final frame] AUDIO: [dialogue, ambience, music, stereo position] REFERENCES: - Image 1 provides [identity / product / style] - Video 1 provides [motion / camera / timing] - Audio 1 provides [voice / rhythm / ambience] PRESERVE: [face, logo, colors, layout, background] AVOID: [unwanted changes or artifacts]
Interface syntax and reference limits can vary. Treat this as a briefing framework, not a provider-specific API schema.
05 / FAQ
What people are asking.
What is MiniMax H3?
MiniMax describes H3 as a general-purpose multimodal generation model that understands text, images, video, and audio in a unified context. It is positioned for generation, references, and editing across creative video workflows.
What can MiniMax H3 generate?
The launch announcement describes video generation up to 15 seconds at 2K resolution with native stereo sound. It also highlights instruction following, text and brand rendering, and video-to-video motion transfer. Exact modes and limits may vary by provider.
Is MiniMax H3 open source?
MiniMax announced plans to release model weights, subject to applicable laws and regulations. Because release status and license terms can change quickly, verify the official ModelScope listing and MiniMax announcement before downloading or deploying.
Is there a MiniMax H3 API?
Third-party model platforms have announced hosted H3 endpoints. This independent guide does not provide an API and does not guarantee any provider’s uptime, pricing, regional access, or parameter support. Confirm details on the provider’s current documentation.
How should I prompt MiniMax H3?
Use a structured brief: subject, action, environment, camera, timing, audio, reference roles, preservation constraints, and unwanted changes. For multi-reference work, explicitly say what each file contributes.
Can MiniMax H3 run locally?
Local requirements depend on the final released weights, precision, runtime, and community optimizations. Avoid relying on speculative VRAM claims; check the official model card and supported workflows once the weights and license are available.
Source discipline
Verify before you build.
H3 is new and availability is moving fast. Product claims on this page are limited to the launch announcement and clearly labeled provider information.
