What LTX 2.3 generates

Native vertical for social

Generates 9:16 directly at up to 1080x1920, no cropping a wide frame. The right shape for TikTok, Reels, and Shorts from the first render.

Synced sound in one pass

Video and audio generate together, so dialogue, SFX, and ambience stay in lockstep with the motion instead of being added later.

Audio-to-video

Feed a track and generate matching visuals. Made for music-led content, ads keyed to a song, and dialogue-driven creative.

Up to 4K and 50 fps

A high resolution and frame-rate ceiling for an open model, so output stays sharp and smooth even at larger sizes.

FAQs

What is the LTX 2.3 AI video generator?
LTX 2.3 is Lightricks' open audio-visual video model. It generates video and sound together in a single pass, so dialogue, effects, and ambience stay locked to the on-screen action. Its standout trait is native vertical output, generated as 9:16 rather than cropped from a wide frame.
Does LTX 2.3 generate audio with the video?
Yes. Video and audio are produced jointly in one pass, so SFX, ambience, and dialogue land in lockstep with the motion instead of being layered on afterward. It also has an audio-to-video mode: feed a track and generate matching visuals.
Is LTX 2.3 good for TikTok and Reels?
Yes. It generates 9:16 directly at up to 1080x1920, so vertical clips are the native shape, not a cropped widescreen frame. That makes it a fit for TikTok, Reels, Shorts, and any social-first, sound-on content.
What resolution and frame rate does LTX 2.3 output?
It reaches up to 4K resolution and up to 50 fps, a higher ceiling than most open video models, with clips up to around 20 seconds. That headroom keeps output sharp and smooth at larger sizes.
Can I use the LTX 2.3 AI video generator online?
Yes. LTX 2.3 has open weights, but you do not need to run it yourself. Morphic hosts it in the browser, so you type a prompt, generate, and the render lands on your Canvas from any laptop, including machines with no GPU.
Is the LTX 2.3 AI video generator free?
Morphic offers a free tier so you can start generating video right away, no payment required. For higher volume or commercial use, paid plans are available.
Can I use LTX 2.3 on Morphic?
Yes. LTX 2.3 is live on Morphic, so you can generate with it right now, alongside other video models like Kling 3.0, Veo 3.1, and Seedance 2.0, all in one workspace.
