A simple, color-coded GGUF workflow for running LTXV-2 in ComfyUI.
Designed to be straightforward and lightweight.

Common Issues

Error: LTXVEmptyLatentAudio – AttributeError

Update Kijai Node Pack to v1.2.8

Checkerboard / patterned noise output

Update all nodes + ComfyUI
(Outdated GGUF loader or ComfyUI build)

Required Node Packs

ComfyUI-GGUF
https://github.com/city96/ComfyUI-GGUF

ComfyUI-KJNodes
https://github.com/kijai/ComfyUI-KJNodes (install & update it to nightly)

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:

• VAE (audio + video)

• Distilled LoRA (REQUIRED)

• Text Projection (embedding connector)

• Other required components

🧠 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

✍️ 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• Most issues = outdated nodes or ComfyUI
