About

LTX Trainer is the training and fine-tuning package in Lightricks' LTX-2 repository (packages/ltx-trainer). It is used to adapt the LTX audio-video diffusion model, for example by training LoRAs for specific characters, visual effects or styles.

According to creator coverage, it supports workflows such as video extension, inpainting/outpainting, audio, and video-to-video training. It sits alongside the repo's inference pipelines (distilled, DFR, retake and others) and the model weights hosted on Hugging Face.

It is run locally from the cloned repository (dependencies installed with uv), so it requires your own GPU hardware. The base model weights are large (the quick-start download is roughly 66 GiB) and are gated on Hugging Face, so the model terms must be accepted before download. The repository license was not shown in the provided material.
