Frequently asked questions
What ByteDance models can I run on ModelRunner?
The catalog has 28 public ByteDance models: LatentSync 1.0, Seedance 2.5 Video to Video, Seedance 2.5 Reference to Video and 25 more. They cover image-to-video, text-to-video, image-to-image, text-to-image and 1 more. Each one has its own page with a free playground, the full input schema, and copy-paste code.
How much do ByteDance models cost?
Pay-per-use, with no subscription: the 18 ByteDance models billed per second of video start at $0.014, and every page publishes its own rate — some are tiered, so a lower resolution or a shorter clip costs less per run. You buy credits and pay only for what you generate.
How do I call a ByteDance model from the API?
POST to https://queue.modelrunner.run/bytedance/latentsync with an Authorization: Key header and the input fields as the top-level JSON body (no wrapper object), then poll the returned status_url and fetch the result from response_url. The JavaScript SDK (@modelrunner/client) wraps that in a single subscribe() call, which is the one place an { input } object is used.
Can I run ByteDance models from Claude or Cursor?
Yes. Connect the ModelRunner MCP server (https://mcp.modelrunner.run/mcp) once and all 28 ByteDance models become tools your assistant can call with run_model — authorized over OAuth 2.1, so no API key goes into a config file. Results come back as hosted URLs in the conversation.
Where is the source code or paper for ByteDance models?
2 of the 28 ByteDance models in the catalog link their own upstream sources — LatentSync 1.0 and SDXL Lightning 4-step — covering some combination of code repository, paper, weights and licence. The links are listed on this page and on each model's own page.
