Quick answer
MiniMax released MiniMax H3 on July 31, 2026. The model is also referred to as Hailuo H3 or Hailuo 3. According to MiniMax's launch announcement, H3 accepts text, image, video, and audio inputs, then generates video with native stereo audio at up to 2K resolution. The official video generation guide confirms text-to-video, first and last frame image-to-video, and multimodal reference generation.
You can access H3 through MiniMax's official platform and API. You can also use the independent MiniMax H3 generator on minimaxh3.tv, which currently offers text prompts, start and end frames, and reference-based generation. The two products do not expose every setting in the same way, so this guide keeps official model specifications separate from the options available on this site.
MiniMax H3 combines text, image, video, and audio context for video generation.
Release date and naming
MiniMax H3 launched on July 31, 2026. MiniMax uses the name MiniMax H3 in its announcement and developer documentation. Hailuo H3 and Hailuo 3 are alternate names people may encounter when searching for the same generation of the model.
The launch post describes H3 as a general-purpose, omni-modal generation model. In practical terms, it is designed to understand several input types within one generation workflow instead of treating text-to-video, image-to-video, and reference-guided creation as unrelated tools.
What MiniMax announced
The official launch material confirms four core points:
- Multimodal input: H3 can understand text, images, video, and audio.
- Video with sound: Output can include native stereo audio rather than requiring a separate audio pass.
- Resolution and length: The official API supports up to 2K output and clips from 4 to 15 seconds.
- Guided control: The supported workflows include first and last frames, visual references, video references, and audio references.
MiniMax also highlights instruction following, text and brand presentation, motion transfer, editing, and controllable generation. These are vendor claims from the July 31 launch material, not independent benchmark results. Exact quality still depends on the prompt, source material, selected workflow, and scene complexity.
Confirmed H3 workflows
Text to video
Text-to-video is the simplest H3 workflow. A prompt describes the subject, setting, action, camera behavior, visual style, and sound. The official API accepts prompts of up to 7,000 characters, although a clear, focused prompt is usually easier to control than a long list of competing instructions.
First and last frame image to video
H3 can animate from a starting image, or use both a starting and ending image to define the transition. This is useful when the opening composition and final composition matter more than a completely open-ended result.
Reference generation
Reference mode can use images, video, and audio as context. The official guide allows up to nine image references, up to three video references with a combined duration of no more than 15 seconds, and up to three audio references. Audio cannot be the only input. The request body limit is 64 MB.
Choose the workflow based on what you need to control: the idea, the transition, or the reference context.
Official H3 vs minimaxh3.tv current availability
| Area | Official MiniMax H3 documentation | Current minimaxh3.tv interface |
|---|---|---|
| Text prompts | Supported | Supported |
| Start frame | Supported | Supported |
| End frame | Supported | Supported |
| Image, video, and audio references | Supported through reference generation | Reference-based inputs are available; controls vary by mode |
| Resolution | Up to 2K | 2K option available |
| Duration | 4 to 15 seconds | 5 to 15 seconds |
| Native stereo audio | Confirmed model capability | No separate audio-generation control is currently exposed |
| API | Official V2 endpoint | The public page is a web generator, not the official MiniMax API |
This distinction matters. A capability listed in MiniMax's API documentation is not automatically a promise that every third-party interface exposes the same parameter or range.
What is not yet confirmed
MiniMax calls H3 an open model in its official documentation. The official pages used for this article do not provide enough detail to verify a specific downloadable weights package, license file, hardware requirement, or community mirror. Those questions should be checked against a current first-party repository or model card before downloading or deploying anything.
The sources also do not establish a universal frame rate, generation speed, success rate, free allowance, or regional availability. These details can change by platform, account, and product configuration, so they are not inferred here.
Where to try MiniMax H3
Developers who need the official API contract should start with MiniMax's Video Generation V2 endpoint. The model identifier is MiniMax-H3, and the request uses a content array to combine prompts and supported references.
For a browser-based workflow, open the MiniMax H3 video generator. You can also browse the video showcase before choosing a workflow. minimaxh3.tv is an independent website and is not affiliated with, endorsed by, or operated by MiniMax.
FAQ
When was MiniMax H3 released?
MiniMax H3 was released on July 31, 2026, according to MiniMax's official launch announcement.
Is Hailuo H3 the same as MiniMax H3?
Hailuo H3 and Hailuo 3 are alternate names used for the same H3 model generation. MiniMax H3 is the name used in the official API documentation.
Does MiniMax H3 generate audio?
Yes. MiniMax states that H3 can generate video with native stereo audio. A specific interface may expose fewer audio controls than the underlying model supports.
What video length does H3 support?
The official H3 API documentation lists 4 to 15 seconds. The current minimaxh3.tv interface offers 5 to 15 seconds.
Can I use images, video, and audio as references?
Yes, through the official reference-generation workflow. Limits and accepted combinations are defined in the current MiniMax video generation guide.
Sources and methodology
This article uses first-party product information checked on August 1, 2026: MiniMax's H3 launch announcement, the official video generation guide, and the official Video Generation V2 API reference. Current site availability was checked against the minimaxh3.tv H3 model page. Vendor capability statements are identified as such, and no independent benchmark claim is made.
