New VAE Architecture
Sharper Fine Details Than Ever
LTX-2.3 introduces a new VAE that produces noticeably sharper output. Textures, facial features, and small objects retain clarity across the full frame. The improvement is especially visible at higher resolutions where previous versions softened details.
Native Audio
Cleaner Sound, Built In
Generate audio natively alongside video with improved clarity in 2.3. Sound effects, ambient noise, and dialogue are synchronized from generation. A dedicated audio-to-video endpoint lets you provide an audio clip and generate matching visuals.
Flexible Workflows
Every Mode You Need
Text-to-video, image-to-video, audio-to-video, extend, and retake. Fast variants for text-to-video and image-to-video when speed matters. Portrait 9:16 support, 24/48 FPS options, and LoRA fine-tuning across the board.
