Flux 3, Seedance, MiniMax, and Grok: A Video Model Spec Showdown

eyishazyer · x · 2026-08-06

Tests on the same prompt reveal core differences among four major video models: Flux 3 (Black Forest Labs) is open-source, generating 20-second clips with synced audio in one pass; Seedance 2.5 (ByteDance) stretches to 30 seconds with 50 reference inputs for storyboard control.

MiniMax H3 features open-weights, 2K clips up to 15 seconds, and native stereo sound; meanwhile, Grok 1.5 Video (xAI) plays a different game, prioritizing dialogue sync and character expressiveness over raw specs.

In direct comparison, Flux 3 notably outperforms Seedance 2.0 in fluid aerial moves, real physics, and scene transitions, whereas Seedance's camera remains flatter and more locked.
