Pixverse v5.6 is the previous-generation Pixverse video model — still production-grade for text-to-video and image-to-video work. Use Pixverse V6 when you want the latest features (multi-clip transitions, six style presets); use v5.6 when you want a stable, predictable workhorse with consistent motion characteristics.
Quality tiers from 360p (cheap iteration) through 1080p (production hero), six aspect ratios covering cinematic through vertical, durations from 5 seconds, optional synced audio generation, and seed pinning for reproducibility.
