LTX-2.3

This is an updated version of the LTX-2 model, developed by Lightricks for synchronized video and audio generation within a single model. It is based on the DiT architecture and integrates key components of modern video generation systems. The model delivers improved audio and visual quality, as well as increased text prompt accuracy.

Key Features:

• Audiovisual content generation based on text, images, video, or audio.
• Supported tasks: Image-to-Video, Text-to-Video, Video-to-Video, Audio-to-Video, Text-to-Audio, and others.
• Built-in audio-video synchronization.
• Limitations:
  • Not designed to provide factual information.
  • Frame size must be divisible by 32; number of frames must be divisible by 8+1.
  • Audio without speech may have low quality.
  • Prompt execution accuracy depends on the writing style. For details, see the Prompting guide.
  • The model is distributed with a warning about the potential generation of inappropriate or offensive content.

For local running, NVIDIA recommends using 24GB+ GPU to generate a 4-second video at 720p24 resolution (with 20 steps).

Use our pre-built public endpoints for free to test inference and explore LTX-2.3 capabilities. You can obtain an API access token on the token management page after registration and verification.

Rent your own physically dedicated instance with hourly or long-term monthly billing.

We recommend deploying private instances in the following scenarios:

• maximize endpoint performance,
• enable full context for long sequences,
• ensure top-tier security for data processing in an isolated, dedicated environment,
• use custom weights, such as fine-tuned models or LoRA adapters.
