Minimax Hailuo 02 Fast API Documentation
Playground
Try it on WaveSpeedAI!Hailuo 02 Fast is a minimax image-to-video model that creates high-quality 6s and 10s clips at 512p for creators and marketers. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.
Features
Hailuo 02 Fast is the speed/throughput variant of the Hailuo 02 engine. It animates a single image into a smooth clip in 6s or 10s, with prompt-aware motion, strong physics, and a cost optimized for rapid iteration and batch A/B testing.
Why it’s useful
- Built for iteration — quick turnarounds for story beats, drafts, and explorations.
- Physics-aware motion — debris, cloth, snow, and handheld shake feel believable.
- Stable temporal flow — fewer flickers; cleaner camera moves.
- Creator-friendly — low cost, predictable results, simple controls.
Parameters
| Name | Description |
|---|---|
| image* | Starting frame (JPG/PNG). Required. |
| prompt | Optional scene/camera/motion description to guide animation. |
| duration | 6s or 10s. |
| enable_prompt_expansion | Auto-refines prompt + safety check. |
| go_fast | Prioritize speed with a moderate quality trade-off (recommended ON). |
How to use (short)
- Upload image (clear subject, good composition).
- Add a concise prompt (camera + lighting + motion).
- Pick duration (6s / 10s), keep go_fast on.
- (Optional) enable prompt expansion.
- Run → review → tweak prompt/seed → re-run.
Pricing
| Duration | Cost per job |
|---|---|
| 6 s | $0.10 |
| 10 s | $0.15 |
Example prompt
A top snowboarder launches off a massive kicker on a cliff’s edge; drone follows, powdered snow billows in bright sunlight; fast shutter, cinematic grade.

Task Submission Parameters
Request Parameters
| Parameter | Type | Required | Default | Range | Description |
|---|---|---|---|---|---|
| image | string | Yes | - | The model generates video with the picture passed in as the first frame.Base64 encoded strings in data:image/jpeg; base64,{data} format for incoming images, or URLs accessible via the public network. The uploaded image needs to meet the following conditions: Format is JPG/JPEG/PNG; The aspect ratio is greater than 2:5 and less than 5:2; Short side pixels greater than 300px; The image file size cannot exceed 20MB. | |
| prompt | string | No | - | The positive prompt for the generation. | |
| duration | integer | No | 6 | 6, 10 | The duration of the generated media in seconds. |
| enable_prompt_expansion | boolean | No | true | - | The model automatically optimizes incoming prompts to enhance output quality. This also activates the safety checker, which ensures content safety by detecting and filtering potential risks. |
| go_fast | boolean | No | true | - | Prioritize faster video generation speed with a moderate trade-off in visual quality |
