LTX-2.3 is a video generation AI that can create videos with voiceovers and background music. It has gained popularity because its AI model is publicly available for free and can be run locally on a personal PC using tools like ComfyUI .

LTX-2.3 allows you to control the art style and easily depict specific people or characters using LoRA and IC-LoRA. While LoRA could be created using the official LoRA development tool, LTX Trainer, it previously required building custom code for each application. With this update, you can now create LoRA and IC-LoRA for a variety of purposes, such as 'generating video from text (T2V)', 'generating video from images (I2V)', 'generating video from audio (A2V)', 'generating video from video (V2V)', 'video extension', 'inpainting', and 'outpainting', simply by rewriting a single configuration file.

Additionally, a SKILL.md file has been released to instruct an AI agent to create LoRA data using LTX Trainer, making it easy for even those unfamiliar with video generation AI to create LoRA data by instructing agents such as Claude Code. However, LoRA training using LTX Trainer requires an NVIDIA GPU with 80GB or more of VRAM. Even when using memory-saving features, a GPU with 32GB or more of VRAM, such as a GeForce RTX 5090, is essential.

Several LoRA demo videos created using the LTX Trainer have also been released. Below is a LoRA example that can generate a consistent video by inputting character images.




LoRA converts videos taken during daylight hours into videos taken at night.




There's also LoRA, which converts black and white videos into color videos.




The example LoRA is available at the following link.
