VisionStory’s native character model turns one image plus text or audio into an identity-consistent performance with natural expression, gestures, and lip-sync.
- Text or recorded audio
- 720p, 1080p, or 2K
- Up to 10 minutes

Model selection guide
Start from the job, then choose the ID.
The best model is the smallest reliable choice for your quality, control, duration, and cost requirements.
Talking avatar video
Recommended
vs_character_v4Use V-Character 4.0 for talking-avatar video. It supports 720p, 1080p, and 2K output with stable motion and natural lip-sync.
Frontier AI video
Recommended
seedance-2.5Use Seedance 2.5 for clips up to 30 seconds, Wan for image/video/audio references, or Kling 3.0 for 4K. Compare per-model limits and credit costs before submitting.
AI image generation
Recommended
seedream-5.0-liteChoose Seedream for 2K or 4K options, Nano Banana for instruction-following edits, or GPT Image for generation and editing through the API. Read each model's live limits and resolution pricing before submitting.
Text to speech
Recommended
Automatic selectionThe TTS endpoint selects the synthesis strategy for the chosen public or cloned voice and input language; you do not pass a public model ID.
VisionStory workspace
A broader model catalog for creative work.
These model profiles are available in the VisionStory creative workspace. A profile name is not automatically a public API model ID.
Developer rule
Only send model IDs returned by the three public model-list endpoints. Do not derive an API ID from a workspace model name.

Let the API tell you what is available.
Model catalogs evolve without changing the endpoint contract. Fetch the catalog when your application starts, validate user choices against the response, and store the returned stable ID with each generation job.
- Accepted aspect ratios, resolutions, and durations
- Reference-media limits and model defaults
- Image credit cost and current availability
