Quick answer
Seedance 2 vs Seedance 2.5 (Spicy): both are ByteDance models — Seedance 2.0 (February 2026) and Seedance 2.5 (July 2026) — and Kenerate runs Spicy image-to-video versions of each for adults 18+. Seedance 2.5 Spicy makes 4–30 second clips; Seedance 2 Spicy, 2 Fast Spicy and 2 Mini Spicy make 4–15 seconds. All four go up to 4K, generate sound with the clip and take an end frame. Pick 2.5 for length, 2 Fast for quicker renders, 2 Mini for the compact tier. Like every Spicy model they're image to video only, and video needs a credit pack.
