Seedance 2.5

Seedance 2.5 is ByteDance's video generation model, launched 31 July 2026 inside Jimeng AI and Doubao Pro. It generates clips up to 30 seconds at 4K in a single run, producing video and audio together in one pass rather than dubbing audio afterwards, and supports multi-turn extension for longer sequences. Its distinguishing feature is an input system accepting up to 50 multimodal references at once — images, text descriptions, style frames, character references and scene direction — used to steer character and style consistency across a shot. API access is stated to be coming via Volcano Engine's Ark platform.
