What it is

LTX-2.3 is Lightricks' open-weight video model, run here as the 22B dev checkpoint with its distilled LoRA on top. It is the alternative to MiniMax H3 in Create Video and Animate Image: a different look, resolution presets from SD to 2K, and a negative prompt, which MiniMax does not have.

Clips default to eight seconds at 30 fps. Above Full HD the app drops the frame rate to 30 and the length to ten seconds to keep the job inside the worker's memory.
