Guide to Downloading and Setting Up Text Encoder Models for ComfyUI

If you've previously downloaded Flux (Unet), setting up the new model is easier than ever! You only need to download the model and the CLIP_G file, then place them in the clip folder to run, as they share the same set of files.

Step 1: Download the Text Encoder Files

First, ensure you have the necessary text encoder files from SD3, Flux, or other models. You’ll need the following files in your ComfyUI/models/clip/ directory:

• clip_l.safetensors
• clip_g.safetensors
• t5xxl

For the t5xxl file, if you have more than 32GB of RAM, I recommend using t5xxl_fp16.safetensors. If not, opt for t5xxl_fp8_e4m3fn_scaled.safetensors for optimal performance.

Step 2: Download the SD3.5 Model

Place the sd3.5_large.safetensors file in your ComfyUI/models/checkpoints/ directory. Note that this file does not contain text encoder/CLIP weights, so you'll need to load them separately. Here are the links for easy downloading:

• clip_g.safetensors: Download from Hugging Face
• clip_l.safetensors: Download from Hugging Face
• t5xxl_fp16.safetensors: Download from Hugging Face

Installation Directory

Make sure all the above files are placed in the correct ComfyUI/models/clip/ directory. For further reference, you can check here: Stable Diffusion 3.5 Large Directory.

Good luck with your installation, and enjoy it (or not)
