Hailuo 2.3 Fast is a speed-optimized variant of MiniMax's Hailuo 2.3 video generation model. It is primarily oriented toward image-to-video workflows, taking a reference image with text prompts to animate it into video output. It retains the realistic motion, human physics, and character consistency of the standard Hailuo 2.3 while delivering roughly 2.5x faster generation and about half the cost, making trade-offs in model size and feature scope for rapid turnaround. It is suited for quick previews, prototyping, social clips, and large-scale batch production.
