Seedance 2.5 — Generate Videos Online

Seedance 2.5 is ByteDance’s newest AI video generation model, announced in June 2026. It extends the Seedance 2.0 family with native long-form clips (up to ~30 seconds of coherent story), stronger multi-shot consistency, and the same synchronized audio generation that made Seedance 2.0 a favorite for short-form creators.

CreateGlow gives you Seedance 2.5 and the whole Seedance 2.x family in one place — no API key, no queue-jumping Discord bots. Type a prompt or upload a first frame, pick a duration and aspect ratio, and generate.
