ByteDance AI Models Explained: Seedance, Seedream, OmniHuman & Seed3D

ByteDance has built one of the most comprehensive AI generation families in the industry. The Seed model family covers video, image, avatar, and 3D generation - and Arteza provides access to all of them through a single platform.

• Digital human experiences

Seed3D - 3D Generation (Deprecated)

Seed3D generated 3D models from images but has been deprecated by the upstream provider. We're evaluating alternative 3D generation models for future integration.

Choosing the Right Model

Workflow Combinations

The real power comes from combining models:

1. Image → Video pipeline: Generate an image with Seedream, then animate it with Arteza
2. Avatar creation: Generate a portrait with Seedream, then bring it to life with OmniHuman
3. Edit → Animate: Upload a photo, edit it with Seedream Edit, then animate with Arteza

Getting Started

Arteza provides a unified platform for all these models with a simple credit system. New accounts receive 10 free credits - enough to try several models and find the right workflow for your needs.
