MiniMax H3 Singularity LoRA API

Introduction

MiniMax H3 Singularity LoRA Reference to video builds one shot from your reference material on Singularity, the community's HDR-trained fine-tune of the open-weights MiniMax H3, with up to three of your own H3 LoRAs loaded. Send up to nine images, three clips and three audio clips, name them by number in the prompt, and get 3 to 15 seconds at 480p to 1080p with a stereo soundtrack in one of seven aspect ratios.

Key features

Choreography from a clip, identity from stills

A reference clip hands over the movement and camera, and still images pin the face and the costume. Singularity's training on fast, high-dynamic-range action keeps that borrowed motion sharp instead of smeared.

Standard H3 LoRAs on a sharper base

Any LoRA trained for MiniMax H3 loads here unchanged. Pair a character LoRA with stills of the same person for the firmest identity hold.

Pricing

Prices are in credits, the same credits you use on the website (1 credit = $0.01). The hold is taken when the task is accepted and settled to the actual charge when it finishes; failed tasks are refunded.

For an exact number before you run, send the same body to POST /jobs/quote.

Use cases

Restage a routine with a new performer

Send the routine as Video 1 and the new performer as Picture 1, then describe the setting. The move carries over; the person and the place are yours.

Consistent fighters across a sequence

Keep each fighter's stills and LoRA fixed and change only the beat you describe. Wide shots keep their faces better on this fine-tune than on the regular model.

Music-driven cuts

Add the track as Audio 1 and ask for movement on the beat. Combined with a reference clip of the dance, the result follows both the rhythm and the choreography.

Prompt guide & pro tips

Keep reference clips short and clean

Trim away the run-up and the landing you do not need, and prefer a locked-off camera in the reference so the model reads the body movement rather than the operator's.

Give each still a single job

One image for the face, one for the outfit, one for the room. Then write the prompt in beats: Picture 1 enters, copies the spin from Video 1, lands facing the camera, with the drum hit from Audio 1 on the landing.

Plan for the render time

Singularity renders more slowly than the regular MiniMax H3 LoRA family; our five-second 480p reference shot took about 80 seconds. Settle the choreography at 480p before stepping up to 1080p.

API quick start

Call the MiniMax H3 Singularity LoRA API in three steps

1. Create an API key. Sign in to PopNow and create a key in the API console. Keys start with sk-popnow- and use the same credits as the website.
2. Send the request. POST /jobs/createTask with model minimax/h3-singularity-lora/reference-to-video and an input object that follows the parameter table. The response returns a task ID straight away.
3. Get the result. Poll GET /jobs/recordInfo with the task ID, or pass a callBackUrl and we post the result to it. Download the output links when the task succeeds.

# 1. Create the task. Keep the Idempotency-Key if you retry after a network error.
export IDEMPOTENCY_KEY="$(uuidgen)"
curl -X POST https://api.popnow.ai/api/v1/jobs/createTask \
  -H "Authorization: Bearer $POPNOW_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: $IDEMPOTENCY_KEY" \
  -d '{
  "model": "minimax/h3-singularity-lora/reference-to-video",
  "input": {
    "prompt": "A slow aerial shot drifting over a misty pine forest at sunrise",
    "reference_image_urls": [
      "https://media.popnow.ai/influencer/examples/ava.webp"
    ],
    "aspect_ratio": "16:9",
    "resolution": "480p",
    "duration_seconds": 5
  }
}'

# 2. Copy data.taskId from the response, then poll until state is succeeded, failed, canceled or expired.
TASK_ID="TASK_ID_FROM_RESPONSE"
curl "https://api.popnow.ai/api/v1/jobs/recordInfo?taskId=$TASK_ID" \
  -H "Authorization: Bearer $POPNOW_API_KEY"

Replace the prompt and any links with your own. The API tab has the response, polling and callback reference.

The regular MiniMax H3 LoRA is quicker and cheaper for calm, slow shots and adds text-to-video. Switch to Singularity when a fight, a dance or a whip pan starts to smear.
