Grok Imagine Video from xAI and Seedance v1 Pro from ByteDance represent two different approaches to AI video generation. xAI's #1 ranked video model with native audio, fast generation, and cinematic quality. On the other side, byteDance's video model with up to 1080p resolution and 12s duration.
Both models cost 80 credits per generation, so the decision comes down to capabilities rather than budget.
