Summary
New in LTX-2.5 are open weights for video, audio, and world simulation. Lightricks describes a 22-billion-parameter diffusion core and a Gemma4-12B text encoder; video and audio are generated in sync across several local execution modes.
The API groups text-to-video, image-to-video, and audio-to-video under ltx-2-5-fast and ltx-2-5-pro. Fast reaches 4K, while Pro offers 720p and 1080p. Both are serving modes of one family.

Video sample from our test
This video exists as a documented run for the exact model version. Playback is muted.
Motion and physical consistency
This sample tests Anatomy, object consistency, camera tracking, rain, and reflections.
Prompt and settings
Generate exactly one continuous five-second 16:9 cinematic video. A fictional bicycle courier in a mustard-yellow raincoat rides a red city bicycle from left to right across a rain-wet Hamburg street at blue hour for the entire clip. The camera tracks her smoothly at waist height. Both hands remain visible on the handlebars, the bicycle geometry stays physically correct, and a transparent umbrella fixed to the bicycle moves naturally in the wind. Wet-street reflections and raindrops follow realistic physics. No cuts, no slow motion, no text, no logos, no subtitles, and no audio.
