Seedance 2 Fast — Next-Gen Video by ByteDance
Seedance 2 Fast is ByteDance's most advanced video generation model. It accepts text prompts and reference images, generates video with native built-in audio, and can pull live context from the web — producing richer, more accurate results than any previous generation.
Text and image input. Use both at once.
Seedance 2 Fast accepts text prompts and reference images simultaneously. Write a description and upload a photo — the model anchors the visual style to your image while following the motion described in your text. More control, more predictable output.
Image for style. Text for motion. One generation.
Audio built in. Not an afterthought.
Every Seedance 2 Fast generation includes native audio — ambient sound, dialogue, music, and effects are created alongside the video frames. No separate audio tool. No post-sync. The sound matches what's on screen because both were generated together.
Audio and video from the same model. No separate step.
Web-connected. Prompts that know what's current.
Seedance 2 Fast can search the web to enrich your prompts with live context. Reference recent events, real products, or current trends. Most AI video models are frozen in time — Seedance 2 isn't.
Generate videos about things that just happened.
