Bytedance is dropping the best video gen model in the world in early July: Seedance 2.5!
The video below (audio on) is the launch video from their Volcano Engine conference this week. It cements China's absolute dominance in video.
- 2x'd generation length of all previous models to 30s, with audio + 4k video
- >5x'd reference images / audio / video to 50
- Allows localized editing (specific characters, closing, detail), will come with copyright filter
Seedance 2 is already the #1 video model and does a whopping $2B in ARR, in a mere 4.5mos! At the current pricing of $2.5/15s, that implies >3.3M hours of video (!) have been generated. That's 3x every feature film ever made and dozens of Netflixes. Only 3 US AI startups make more revenue.
