ByteDance Seedance Series Video Generation Models Launch on B.AI API

B.AI announced that ByteDance's Seedance series of video generation models is now accessible via API, with full access supported by the official team. This launch introduces four models spanning tiers from flagship to lightweight: Seedance 2.5 focuses on multimodal audio-video co-generation, supporting sequences up to 30 seconds long at up to 1080p 10-bit, and allows up to 50 reference assets alongside targeted timestamp editing; Seedance 2.0 prioritizes high-fidelity output, supporting up to 4K 10-bit with synchronized audio, and enables control over start and end frames as well as forward and backward extension; Seedance 2.0 Fast strikes a balance between speed and cost, delivering rapid 480p/720p generation suited for ad variations and storyboard iteration; Seedance 2.0 Mini offers a lower unit price tailored for budget-conscious creation and prompt experimentation. Developers can now invoke these models via the B.AI API. Visit chat.b.ai/chat to experience them.
