LTX2 Distilled Refine LoRA

This repo contains the distilled LoRA used for LTX-2 two-stage refinement. FastVideo loads it only when ltx2_refine_enabled=True (or the equivalent refine flags). The base model repo can reference this LoRA via fastvideo_refine_lora_path in model_index.json, so users do not need to pass the LoRA path manually.

Contents

• ltx-2-19b-distilled-lora-384.safetensors — distilled LoRA weights for the stage-2 refine denoising pass.

Usage (FastVideo)

Use a distilled LTX-2 diffusers repo that includes fastvideo_refine_lora_path="FastVideo/LTX2-Distilled-LoRA" in its model_index.json. Then enable refinement:

from fastvideo import VideoGenerator

generator = VideoGenerator.from_pretrained(
    "FastVideo/LTX2-Distilled-Diffusers",
    ltx2_refine_enabled=True,
)

FastVideo will download this LoRA repo automatically only when refinement is enabled.
