Direct answer
Seedance 2.0 is ByteDance's multimodal audio-video generation model. It accepts text, image, audio and video references and is designed for generation, extension and editing.
The official launch describes up to 15-second audio-video output and combined references. Practical uses include storyboards, ads, explainers and scenes where motion and sound must be planned together.
This page answers the search question “what is seedance 2.0” with current, source-linked information and a practical check you can repeat.
What the official pages establish
- seed.bytedance.com: ByteDance's launch page documents Seedance 2.0's text, image, audio and video inputs, up to 15-second audio-video output, and reference and editing capabilities.
- docs.byteplus.com: BytePlus documents usage-based Seedance 2.0 API pricing. Cost changes with resolution, duration and whether the request contains video input; its calculator or returned token usage is the reliable estimate.
- yeha.ai: yeha.ai currently lists Seedance 2.5, Seedance 2.0 and Seedance 2.0 Fast in its video workspace. The selected model and settings determine the credit quote shown before generation.
How to make the decision
Choose 2.0 when its input mix or documented API fits the job. Choose another version when you need a different duration, price or platform workflow.
A useful rule: Treat a model announcement, a platform listing and access in your own account as three separate checks. The account screen and pre-generation quote are the final operational evidence.
Practical next steps
- Confirm the exact model version in the selector.
- Review duration, resolution, references and audio options before generating.
- Read the displayed credit quote before submitting the job.
- Keep the prompt, inputs and settings so a result can be reproduced or diagnosed.
Open the yeha.ai creative workspace and check the current video model selector. If pricing determines the decision, read the current pricing page before submitting a generation.
What to avoid
Do not confuse Seedance 2.0 with ByteDance's general Seed 2.0 language-model family.
