Qwen3.5 for ComfyUI

Qwen3.5 for ComfyUI

Repackaged Qwen3.5 2B, 4B and 9B model files for ComfyUI's text encoder folder, in bf16 and two quantized styles for the 9B size. For ComfyUI users who need a Qwen3.5 text encoder.

Made by Comfy-Org on Hugging Face. These notes are Mindket's, written from its model page and model card; the model's own files and license are on Hugging Face.

About

What it is: These are Qwen3.5 model files repackaged for ComfyUI. They come in 2B, 4B and 9B sizes, with extra quantized files for the 9B model, and they belong in the text_encoders folder. The card is short and does not say which workflows use them. The originals are the Qwen3.5 models from Qwen.

Who it suits: It suits ComfyUI users whose workflow asks for a Qwen3.5 text encoder and who want a ready file in the right format.

Industry | Who uses it | How they use it | Example
Design and art | ComfyUI artists | Load a Qwen3.5 text encoder for a workflow that needs one | They pick the 2B file in the encoder node
Software development | Developers who build ComfyUI pipelines | Swap between sizes in a workflow | They try the 9B file in place of the 4B file
Local AI hobby | Users with limited memory | Choose a smaller precision of the 9B model | They try the int8 or w4a8 file

You can skip it if you do not use ComfyUI, or if your workflow does not call for a Qwen3.5 text encoder.

Where to use it:

• ComfyUI, on Windows, macOS or Linux
• The text_encoders folder under ComfyUI/models
• Python with the Hugging Face tools, to download the files

Use case | Who | What they get back
Provide a text encoder | ComfyUI users | A Qwen3.5 file the workflow can load
Try a smaller file | Users with limited memory | A quantized copy of the 9B model
Compare sizes | Pipeline developers | 2B, 4B and 9B files side by side

How to set it up: You need ComfyUI and a place for the downloaded files.

• A working ComfyUI install
• Python with the huggingface_hub package
• Disk space for the files you choose to keep

1. Install the Hugging Face tools with Python.
2. Download the repository files with the second command below.
3. Place the files you want in the text_encoders folder under ComfyUI/models.
4. Restart ComfyUI if it was open, then pick the file in your workflow.

pip install -U huggingface_hub
hf download Comfy-Org/Qwen3.5

Title: The five files, all for the text_encoders folder
Model size | Precision | File
2B | bf16 | qwen3.5_2b_bf16.safetensors
4B | bf16 | qwen3.5_4b_bf16.safetensors
9B | bf16 | qwen3.5_9b_bf16.safetensors
9B | int8 convrot | qwen3.5_9b_int8_convrot.safetensors
9B | w4a8 gptq | qwen3.5_9b_w4a8_gptq.safetensors

How to use it: The card gives no command and names no workflow. After the files are in place, choose one in a ComfyUI node that loads a text encoder, and check that workflow's own notes for the file it expects.

Tool | What it does
text_encoders folder | Where ComfyUI looks for these Qwen3.5 files
Hugging Face download command | Fetches every file in the repository

Example: You place the 2B bf16 file in the text_encoders folder and select it in a workflow that asks for a text encoder. The workflow then reads your prompt through that encoder. The card does not describe the workflow itself.

For newcomers and experts: Think of these as the language-reading part that some ComfyUI workflows need. A first small try is to download one file, place it in the folder and select it in a workflow that asks for it.

The file names show three model sizes and three precision styles: bf16 for all sizes, plus int8 convrot and w4a8 gptq for the 9B model. The card does not compare them, so check your workflow's notes before choosing. Smaller precisions usually trade some accuracy for less memory, but the card gives no measurements.

Place one in ComfyUI/models/text_encoders

Run the workflow that uses it

Good to know:

• Repackaged files: they are Qwen3.5 weights arranged for ComfyUI, and the originals are Qwen's 2B, 4B and 9B models
• Short card: there is no workflow list, so check each workflow's own notes
• Other versions: other people have published 2 quantized versions
• License: Apache 2.0
• Cost to run: none named
• Data it reaches: the files you download and the prompts you run in ComfyUI
• Not for: use outside ComfyUI, since the files are repackaged for it
