AI short drama & video creation

Short dramas and story videos need several kinds of model working together: a text model to break the script down, an image model for characters and keyframes, a video model to animate each shot, and voice or music on top. BigModel.io serves all of them with one key and one USD balance, and adds a workflow API that chains them for you.

Five steps, one request

1. 01Find the charactersCharacters and their look, from the script.
2. 02Write the storyboardScenes cut into 4–15 second shots.
3. 03Character sheetsOne reference image per character keeps them consistent.
4. 04First framesAn image model draws each shot's first frame.
5. 05Video clipsA video model animates each frame, with native audio.

What you can build

The multimodal lineup

From script to clips in one call

POST /v1/workflows/short-drama takes a script and returns a workflow ID right away. The workflow extracts the characters and draws a reference image for each, writes a storyboard, renders a first frame per segment, then animates every frame into a clip. Poll GET /v1/workflows/{id} to read the characters with their images, the storyboard, and each segment with its frame and video URLs as they finish.

curl https://bigmodel.io/v1/workflows/short-drama \
  -H "Authorization: Bearer $BIGMODEL_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Idempotency-Key: episode-1" \
  -d '{
    "script": "A courier finds a letter addressed to herself, dated ten years from now...",
    "style": "cinematic, warm evening light",
    "aspect_ratio": "9:16",
    "max_segments": 6
  }'

# Poll until status is succeeded; cancel with POST …/cancel
curl https://bigmodel.io/v1/workflows/WORKFLOW_ID \
  -H "Authorization: Bearer $BIGMODEL_API_KEY"

• Every step is billed at the listed price of the model it uses; failed steps are not charged. Use dry_run for an estimate first.
• Send an Idempotency-Key header: retrying with the same key returns the same workflow instead of starting a new one.
• Cancel a running workflow with POST /v1/workflows/{id}/cancel. Steps already finished stay billed.
