additional install via manager

📦 Downloads

🧩 Kijai’s Repo (ALL files except diffusion models — choose ONE LoRA)

https://huggingface.co/Kijai/LTX2.3_comfy/tree/main

Includes:

Distilled LoRA ( REQUIRED )

Text Projection (embedding connector)

🧠 Diffusion Models (GGUF)

https://huggingface.co/unsloth/LTX-2.3-GGUF/tree/main

Choose based on VRAM:

Q4_K_M → lower VRAM ( recommended )

Q8_0 → higher quality, more VRAM

⚠️ Very low quants = basically unusable

Includes:

VAE (audio + video)

GGUF models

✍️ Text Encoders ( REQUIRED )

Option 1 – Gemma (recommended for low VRAM)

https://huggingface.co/Comfy-Org/ltx-2/tree/main/split_files/text_encoders

Option 2 – Full version (higher VRAM, better quality)

➡️ You still ALSO need:

Text Projection (from Kijai’s repo)

🔍 Latent Upscaler

https://huggingface.co/Lightricks/LTX-2/tree/main/

Files:

ltx-2-spatial-upscaler-x2-1.0.safetensors

ltx-2-temporal-upscaler-x2-1.0.safetensors

⚠️ Important Notes

Use DEV GGUF diffusion models (no distilled base model yet)

Distilled LoRA is still REQUIRED

Most issues = outdated nodes or ComfyUI
