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.

What LTX-2.5 can do

“n/a” means the provider does not state it or we have not sourced it yet. That is not a “no”.

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.

Independent evaluation. WorldGuide Bench Table 2, exact model row "LTX-2.5-22B"; unstarred baseline is given the complete ground-truth action plan and generates the procedure step by step. The score is the paper's video-judged task-success rate.
Context
These are end-to-end procedural video-task baseline results under the stated conditioning, not an autonomous agent-system result or an unconditional generic video-quality score. The paper gives model labels and relevant task conditions, but no immutable serving/checkpoint digest or confidence interval. A per-model valid denominator is omitted where the paper does not state it.
