ComfyUI Qwen3-VL GGUF (8B & 4B) โ€” Unified Hybrid & Split mmproj Editions

GGUF quantizations of Qwen3-VL extracted from Comfy-Org's Qwen3-VL repackaged weights.

This repository provides two distinct formats depending on your runtime:

  1. ๐Ÿ”ฅ NEW: Unified Single-File Hybrid GGUFs (*_vision_q8_0.gguf) โ€” Combines the K-quantized LLM backbone (Q4_K_M / Q5_K_M) and the Q8_0 Vision Tower + DeepStack Mergers + 5D Conv3d shape metadata (comfy.gguf.orig_shape) inside a single file.
  2. Split LLM + Standalone mmproj GGUFs โ€” Standard two-file format for llama.cpp, llama-server, Ollama, and split VLM loaders.

Model Overview

  • Original Weights Source: Comfy-Org/Qwen3-VL
  • Underlying Architecture: Alibaba Cloud Qwen3-VL (Qwen3VLForConditionalGeneration / qwen3vl)
  • Hybrid Format Vision Precision: Q8_0 Vision Tower & DeepStack Mergers + F32 LayerNorms/Biases + preserved 5D [1152, 3, 2, 16, 16] patch embedding metadata
  • Split Format Projector Precision: Standalone F16 GGUF (mmproj) preserving full vision patch fidelity
  • Quantization Engine: llama.cpp k-quants + custom ComfyUI-GGUF-Loader hybrid tensor packer

Available Files & Specifications

1. Unified Single-File Hybrid Series (Recommended for ComfyUI)

Contains both the Language Backbone (blk.*) and Vision Tower (model.visual.*) in a single GGUF file.

qwen3vl_8b_q4_k_m_vision_q8_0.gguf Q4_K_M Q8_0 / F32 5.62 GB All-in-one hybrid GGUF. Best speed/VRAM balance for ComfyUI-GGUF-Loader (no external mmproj needed).
qwen3vl_8b_q5_k_m_vision_q8_0.gguf Q5_K_M Q8_0 / F32 ~6.39 GB All-in-one hybrid GGUF. Higher-precision text backbone paired with Q8_0 vision & DeepStack mergers.

2. Split 8B Series (LLM + Standalone mmproj)

For llama.cpp, llama-server, or split-loader workflows.

File Name Precision File Size Description
mmproj-qwen3vl-8b-f16.gguf F16 1.08 GB Standalone multimodal vision projector (pair with split 8B files below)
qwen3vl-8b-Q4_K_M.gguf Q4_K_M 4.68 GB Optimal balance of generation speed, memory, and accuracy
qwen3vl-8b-Q5_K_M.gguf Q5_K_M 5.45 GB Balanced higher-precision text backbone
qwen3vl-8b-Q6_K.gguf Q6_K 6.26 GB Near-lossless language reasoning and instruction following

3. Split 4B Series (LLM + Standalone mmproj)

File Name Precision File Size Description
mmproj-qwen3vl-4b-f16.gguf F16 0.78 GB Standalone 4B Multimodal vision projector
qwen3vl-4b-Q4_K_M.gguf Q4_K_M 2.33 GB Ultra-lightweight edge quant for low-memory environments
qwen3vl-4b-Q5_K_M.gguf Q5_K_M 2.69 GB Higher-precision 4B variant

Quickstart & Usage

Option A: Unified Single-File Setup

  1. Download either qwen3vl_8b_q4_k_m_vision_q8_0.gguf or qwen3vl_8b_q5_k_m_vision_q8_0.gguf and place it into:
    ComfyUI/models/text_encoders/
    # or
    ComfyUI/models/clip/
    
  2. Load it directly inside ComfyUI using the CLIPLoader (GGUF) node

Option B: Split Two-File Setup (llama.cpp / Split ComfyUI Loaders)

  1. Place your desired language GGUF (e.g., qwen3vl-8b-Q4_K_M.gguf) into:
    ComfyUI/models/unet/
    # or
    ComfyUI/models/text_encoders/
    
  2. Place the matching projector (e.g., mmproj-qwen3vl-8b-f16.gguf) into:
    ComfyUI/models/clip_vision/
    
  3. Load the model using your split GGUF loader or via llama.cpp CLI/Server:
    llama-server -m qwen3vl-8b-Q4_K_M.gguf --mmproj mmproj-qwen3vl-8b-f16.gguf
    

Technical Verification (Hybrid Series)

Both qwen3vl_8b_q4_k_m_vision_q8_0.gguf and qwen3vl_8b_q5_k_m_vision_q8_0.gguf have been validated end-to-end:

  • 750 Total Tensors: 399 LLM tensors (Q4_K_M or Q5_K_M) + 351 Vision tensors (Q8_0 weights + F32 norms/biases).
  • 5D Patch Embedding Metadata: Includes comfy.gguf.orig_shape.model.visual.patch_embed.proj.weight = [1152, 3, 2, 16, 16] for 3D temporal-spatial patch projection.
  • DeepStack Mergers: All 3 DeepStack spatial mergers ([4096, 4608]) and final vision-to-LLM merger verified with zero NaN/Inf values during multimodal forward passes.
