ByteDance Launches Seedance 2.5 Flash: Twice the Speed, 34% Cheaper
On November 12, ByteDance officially released the video generation model Seedance 2.5 Flash, positioned as a cost-effective version for high-volume content production. The company says its quality is "closest" to the flagship Seedance 2.5, with roughly double the generation speed (about 2x faster) and a price cut of about 34%.
Confirmed
- Pricing: via Volcano Engine, 720p text-to-video/image-to-video costs about RMB 0.99 per second, roughly 34% lower than Seedance 2.5, or about RMB 9.9 for a 10-second clip (@Volcano Engine, @zhidx)
- International BytePlus pricing for 720p text-to-video/image-to-video is $0.152 per second (@aziz4ai, @matchaman11)
- Specs: supports 720p text-to-video and image-to-video, up to 30 seconds per clip, plus a 480p tier
- API opens on November 15 (Sunday) (@lyraxana)
- @zhidx tested the model and found it competitive, consistent with the official claim of quality "closest to Seedance 2.5"
Why it matters
Seedance 2.5 Flash doubles speed and cuts prices sharply while maintaining near-flagship quality, significantly lowering the unit cost of video generation. That directly boosts commercial adoption in scenarios like mass content production and advertising, and will intensify price competition in the video generation model market.
