ByteDance Seedance series video generation model launched B.AI API

On October 28, B.AI announced that ByteDance's Seedance series video generation models have been integrated into the API, with official support for full access. A total of four models have been launched, covering different tiers from flagship to lightweight.

Seedance 2.5 focuses on multimodal audio-visual joint generation, with a maximum single duration of 30 seconds, up to 1080p 10-bit, supporting up to 50 reference materials and targeted timestamp editing; Seedance 2.0 emphasizes high-quality output, supporting up to 4K 10-bit with audio-visual synchronization, and allows control of the first and last frames as well as extensions before and after; Seedance 2.0 Fast balances speed and cost, providing quick generation at 480p/720p, suitable for advertising variants and storyboard iterations; Seedance 2.0 Mini meets budget-sensitive creative and prompt testing needs at a lower unit price. Developers can now call the above models through the B.AI API, and are welcome to log in to chat.b.ai/chat to experience it.
