FAQs

What is LTX 2.3?
LTX 2.3 is Lightricks' open-source audio-visual video generation model. It generates synchronized video and audio in a single pass, supports native vertical output up to 4K, and runs at up to 50 fps.
How is LTX 2.3 different from earlier LTX versions?
2.3 ships a rebuilt variational autoencoder, a quadrupled text encoder built on Gemma 3 12B, and a gated-attention text connector for better prompt adherence. Resolution, frame rate, and audio quality all step up over LTX-2.
Does LTX 2.3 support vertical video?
Yes, natively. The model generates 9:16 directly at full resolution rather than cropping a horizontal frame, which keeps detail and composition right for vertical-first surfaces.
What does audio-to-video do?
Feed in an audio clip and LTX 2.3 generates matching visuals timed to the audio. Useful for music-driven content, ads keyed to a track, or dialogue-led shorts where the audio sets the pacing.
How do I use LTX 2.3 on Morphic?
Open Copilot, describe the shot or attach an audio track, and pick LTX 2.3. For vertical short-form, audio-led content, or anything that benefits from native sound generation, LTX 2.3 is the right pick.
Is LTX 2.3 really open weights?
Yes. Lightricks publishes the weights on Hugging Face under the LTX-2 Community License. On Morphic you use the hosted version, no infrastructure to manage, but the underlying model is openly available for local or on-prem use.
