Where to put it

Put the file in ComfyUI/models/text_encoders/ (in the portable version: ComfyUI_windows_portable/ComfyUI/models/text_encoders/). Older guides say models/clip: that folder still works. Then press R in ComfyUI, or restart it, so the file shows up in a text-encoder loader: Load CLIP (CLIPLoader) for one encoder, DualCLIPLoader when the model takes two (FLUX.1: CLIP-L + T5-XXL).

If a workflow says “Value not in list” for this node, the file name in the workflow is different from yours, or the file is in another folder. Click the node and pick the file from the list.

What it does

A text encoder turns your prompt into numbers the model understands. It runs once per prompt, then ComfyUI can move it out of VRAM to make room for the image model — so it costs load time and system RAM more than speed.

This is a smaller NVFP4 version. It loads faster and needs about half the RAM of the 16-bit file; the difference in the pictures is usually hard to see. It is the version this site lists by default.

FP4 needs an RTX 50 (Blackwell) card to run at full speed; on older cards take another version.
