minimax-h3/v1/videos/generationsminimax/minimax-h3hailuo-3minimax/hailuo-3Live pay-as-you-go rates from the EmpirioLabs catalog. You are billed only for what you use, with no monthly minimum.
MiniMax H3 runs through POST /v1/videos/generations. The request returns a job_id right away; poll GET /v1/jobs/{job_id} until the job completes and read the output URLs from the result. Get an API key from the EmpirioLabs dashboard.

time.sleep(5)Request parameters supported by the MiniMax H3 API on EmpirioLabs. Defaults apply when a field is omitted.
| Parameter | Type | Default | Range / values | Description |
|---|---|---|---|---|
| prompt | string | - | - | Scene description, up to 7000 characters. Can describe action, camera work, dialogue, sound effects, and on-screen text. |
| mode | enum | auto | auto, t2v, i2v, flf, r2v, regenerate | auto: detect from the inputs. t2v: text-to-video. i2v: animate one image as the opening frame. flf: transition from a first frame to a last frame. r2v:... |
| resolution | enum | 768p | 768p, 2k | Output resolution. 2K is billed at a higher per-second rate than 768p. |
| aspect_ratio | enum | adaptive | adaptive, 21:9, 16:9, 4:3, 1:1, 3:4, 9:16 | Output aspect ratio. Adaptive follows the supplied input media. |
| duration | number | 6 | 4 to 15 | Clip length in seconds, whole numbers only. |
| image | string | - | - | Image URL. One opening frame for image-to-video, or up to 9 reference images for reference-to-video. |
| last_frame | string | - | - | Closing frame image URL. Supplying it selects first and last frame mode. |
| video | string | - | - | Reference video URL, up to 3 clips of 2 to 15 seconds each. Reference video is billed for its own duration in addition to the generated clip. |
| audio | string | - | - | Reference audio URL, up to 3 clips of 2 to 15 seconds each. Requires an accompanying reference image or video. |
| base_video | string | - | - | A 768p clip previously generated by this model, to re-render at 2K. Supplying it selects regeneration, which is billed at its own lower per-second rate on the source... |
| watermark | boolean | false | - | Add the AI-generated content watermark to the output. |
| enhance_prompt | boolean | false | - | Expand your brief into a full prompt before rendering, adding shot structure, camera work and a soundscape. Any reference media you attach informs the expansion.... |
MiniMax H3 generates 4 to 15 second clips at 24 fps in 768p or 2K, each with a native stereo audio track.
Set enhance_prompt to true and the model first rewrites your brief into a full prompt, adding shot-by-shot structure, camera moves, lighting and a soundscape, then renders from that. Any reference media you attach informs the expansion. It adds a per-token charge on top of the per-second video cost, and is skipped for regeneration because that path reproduces the original request.
On EmpirioLabs, MiniMax H3 is billed pay as you go: 768p $0.18 per second; 2K $0.26 per second; 2K regeneration $0.10 per second. The live rate card on this page always matches what the API charges.
MiniMax H3 is served through POST /v1/videos/generations on api.empiriolabs.ai with standard bearer-token authentication.
Yes. The EmpirioLabs playground runs MiniMax H3 in the browser with the same parameters the API exposes, so you can test prompts before writing code.
Create an EmpirioLabs account, then generate a key under API Keys in the dashboard. Billing is pay-as-you-go credits, so you only pay for the requests you make.
