Quick take
Alibaba's unified video family for creating short clips with sound from text, a starting image, or a reference video.
The endpoints, accepted references, and defaults are not identical. Check watermark settings, content rules, live per-second pricing, and continuity across each shot before planning a campaign.
LTX's speed-optimized video model for text, image, or audio input, native sound, automatic duration, and output up to 4K.
Fast does not mean every 4K job finishes instantly. Price grows from $0.09 to $0.30 per generated second, and permitted duration depends on resolution and frame rate.
