Rainforest at Golden Hour

An aerial shot drifts over a dense rainforest at golden hour, with mist rising from the canopy and a waterfall cascading into a dark green pool.

“A wide aerial shot slowly drifts over a dense rainforest at golden hour. Thick mist rises from the canopy as shafts of warm orange light pierce through the trees. A winding river reflects the fading sky below. The camera tilts down gradually, revealing a waterfall cascading into a dark green pool. Ambient sounds of water and distant birds fill the scene.”

Competitive Cyclist - 1

Competitive Cyclist

A side-tracking shot follows a competitive cyclist in a red, white and blue racing kit powering along a wet road at full speed. He is crouched low over the handlebars in an aggressive aero position, legs driving the pedals in a fast, powerful cadence. The camera tracks him at pace from the left, keeping him centered in frame. Trees and guardrails blur into streaks of green and grey behind him. Rain mist rises off the road surface. His jersey ripples in the wind. The sound of spinning wheels, fast breathing, and wet road noise fill the audio. The camera slowly pushes in toward his focused expression as he accelerates.

LTX-2.3 is a 22 billion parameter DiT-based audio-video foundation model by Lightricks, released on March 5, 2026. It features a completely rebuilt VAE for sharper textures, faces, hair, and text rendering, a 4x larger text connector for better prompt adherence, native 9:16 portrait support, LoRA adapter support, and a new HiFi-GAN vocoder for cleaner audio. It is open-source under Apache 2.0.
LTX-2.3 introduces several major upgrades: the VAE has been completely rebuilt for dramatically sharper fine details. The text connector is 4x larger, resulting in much better prompt adherence. Image-to-video generation has been improved with less Ken Burns effect and less freezing. Audio quality is cleaner thanks to a new HiFi-GAN vocoder. It also adds native 9:16 portrait video support and LoRA adapter support for customization.
LTX-2.3 generates videos from 480p up to 1080p natively, with upscaling support to 4K. It supports both landscape (16:9) and portrait (9:16) aspect ratios, with portrait mode supporting up to 1080x1920 resolution. Video duration ranges from 5 to 20 seconds, with frame rate options of 24 or 48 FPS.
LTX-2.3 supports up to 3 simultaneous LoRA (Low-Rank Adaptation) adapters that can be applied to customize the model's output. LoRAs can be used to maintain consistent character appearances, apply specific artistic styles, or control motion patterns. This allows for brand-specific customization and specialized creative workflows without retraining the full model.
LTX-2.3 generates synchronized audio-video content using a new HiFi-GAN vocoder that produces cleaner, higher-fidelity audio compared to LTX-2. The model generates contextually appropriate sound effects, ambient audio, and dialogue that naturally matches the visual content. Audio generation can be toggled on or off depending on your needs.
Yes, LTX-2.3 is released under the Apache 2.0 license, which is one of the most permissive open-source licenses available. The full model weights and training code are publicly accessible, allowing developers to build custom applications, fine-tune for specific use cases, or integrate the model directly into production pipelines for both personal and commercial use.
