ByteDance Models API - Access Seedream and Seedance via AIsa

AIsa routes ByteDance Seedream and Dreamina Seedance models through BytePlus, ByteDance’s official international enterprise platform. Use one AIsa API key for Seedream image models and Seedance video models. seedream-5-0-260128 uses POST /v1/images/generations and is billed per request. Dreamina Seedance video models are asynchronous through POST /v1/video/generations.

Supported ByteDance models

Model ID	Context	Capabilities	Best for
`seedream-5-0-260128`	262,144	Image, Vision	Newer Seedream image route
`dreamina-seedance-2-0-260128`	—	Video	Dreamina Seedance video generation
`dreamina-seedance-2-0-fast-260128`	—	Video	Faster, lower-cost Seedance video route
`dreamina-seedance-2-5`	—	Video	Newer Dreamina Seedance video route

Current prices for these models are on aisa.one/models. The date suffix in each model string is a release/version stamp in YYMMDD format, useful when pinning a production route. Dreamina Seedance video models are asynchronous: submit the job to POST /v1/video/generations, then poll /v1/video/generations/{task_id}. A — in the Context column means the current gateway metadata does not publish that model’s context window.
