What is Seedance 2.0 and who developed it?

Seedance 2.0 is an AI video generation model developed by ByteDance — the company behind TikTok. It can create high-quality videos from text prompts (text-to-video) or from uploaded images (image-to-video). Seedance 2.0 is available on PicX Studio in two variants: Seedance 2.0 Pro for maximum cinematic quality, and Seedance 2.0 Fast for quicker video generation. It supports durations from 4 to 15 seconds across six aspect ratios.
