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

On October 28, B.AI announced that ByteDance's Seedance series of video generation models have been integrated into the API, with official support for full-scale access. This release includes four models covering different tiers from flagship to lightweight: Seedance 2.5 focuses on multimodal audio-visual joint generation, supporting single runs up to 30 seconds and resolutions up to 1080p 10-bit, accommodating up to 50 reference assets and targeted timestamp editing; Seedance 2.0 emphasizes high-fidelity output, supporting up to 4K 10-bit and audio-video synchronization, while allowing control over start and end frames as well as forward and backward extension; Seedance 2.0 Fast strikes a balance between speed and cost, providing rapid generation at 480p/720p, ideal for ad variants and storyboard iteration; Seedance 2.0 Mini caters to budget-conscious creation and prompt experimentation needs with a lower unit price. Developers can now invoke the aforementioned models via the B.AI API. You are welcome to log in to chat.b.ai/chat to try it out.
