› In short: Seedance 2.5 Flash is the faster version of ByteDance's Seedance 2.5.
› It makes 4 to 30 second clips at 480p or 720p with sound, from text, an image or references.
› ByteDance says results are close to the full model at roughly twice the speed.
› I ran three clips at 720p: each was ready in about 2.5 to 3 minutes.
