About RelayDance

RelayDance (relaydance.com) is an AI video generation platform. It relays the ByteDance Seedance model family (Seedance 2.0 from 480p to native 4K, Fast and Mini variants, Seedance 1.5 Pro), HappyHorse video models, gpt-image-2 image generation and Seedance super-resolution through one OpenAI-compatible API and a web console.

The platform is built for developers and studios that want production video generation without enterprise onboarding: no queue, no BytePlus enterprise account and no KYC, with asynchronous tasks, webhook callbacks, multi-reference fusion and per-second billing where failed requests are never charged.

The service is operated by a Cayman Islands exempted company, as set out in the Terms of Service. Upstream inference runs on BytePlus (the international arm of ByteDance) infrastructure, and generated output is delivered from BytePlus object storage.

Live model list and rates are on the models page; integration guides are in the documentation. For anything else, see the contact page.
