Happy Horse 1.1 vs LTX 2.3 Pro
Use Happy Horse 1.1 when the story depends on native audio, lip-sync, dialogue, and reference characters in short marketing or UGC scenes. Use LTX 2.3 Pro when the project needs longer clips, higher-resolution delivery, 4K headroom, extension or retake workflows, and broader production finishing. This comparison helps separate an audio-first actor model from a more flexible production and editing model.
