Qwen3.6-27B — GGUF Quantizations (VLM)

Quantized GGUF versions of Qwen/Qwen3.6-27B

This is a Vision-Language Model (VLM) — it can understand both text and images.

Works with llama.cpp · LM Studio · Jan · Ollama

Quantized by Dhptl on June 16, 2026 using quant-kit

[!IMPORTANT] This VLM requires TWO files — a text backbone GGUF and the mmproj vision encoder GGUF. Download one text backbone (e.g. Q4_K_M) and the mmproj file. Both must be in the same folder.

📦 Available Files

🔤 Text Backbone (quantized — pick ONE)

Filename	Size	RAM Required	Quant	Quality	Best For
`Qwen3.6-27B-Q2_K.gguf`	0.98 GB	~2.5 GB	`Q2_K`	⭐	Extreme compression, significant quality loss.
`Qwen3.6-27B-Q3_K_L.gguf`	13.56 GB	~15.1 GB	`Q3_K_L`	⭐⭐⭐	Slightly better than Q3_K_M, still a compromise.
`Qwen3.6-27B-Q3_K_M.gguf`	12.57 GB	~14.1 GB	`Q3_K_M`	⭐⭐⭐	Very small file. Quality drop noticeable.
`Qwen3.6-27B-Q3_K_S.gguf`	11.41 GB	~12.9 GB	`Q3_K_S`	⭐⭐	Very high compression, high quality loss.
`Qwen3.6-27B-Q4_K_M.gguf`	15.66 GB	~17.2 GB	`Q4_K_M` ✅ Recommended	⭐⭐⭐⭐	Best balance of size and quality. Recommended for most users.
`Qwen3.6-27B-Q4_K_S.gguf`	14.74 GB	~16.2 GB	`Q4_K_S`	⭐⭐⭐½	Good speed/size balance, slight quality loss.
`Qwen3.6-27B-Q5_K_M.gguf`	18.19 GB	~19.7 GB	`Q5_K_M`	⭐⭐⭐⭐½	Better quality than Q4, slightly larger. Great if you have the RAM.
`Qwen3.6-27B-Q5_K_S.gguf`	17.67 GB	~19.2 GB	`Q5_K_S`	⭐⭐⭐⭐	Large but accurate.
`Qwen3.6-27B-Q6_K.gguf`	20.89 GB	~22.4 GB	`Q6_K`	⭐⭐⭐⭐⭐	Near-perfect quality, very large.
`Qwen3.6-27B-Q8_0.gguf`	27.05 GB	~28.6 GB	`Q8_0`	⭐⭐⭐⭐⭐	Closest to original quality. Use when RAM is not a concern.

🖼️ Vision Encoder — mmproj (always required, always F16)

Filename	Size	Notes
`Qwen3.6-27B-mmproj-f16.gguf`	0.86 GB	Always F16 — vision encoder is not quantized

⚠️ You need BOTH files — one text backbone + the mmproj — to run this VLM.

🚀 How to Use

LM Studio (Easiest — GUI)

Search for Dhptl/Qwen3.6-27B in LM Studio
Download the Q4_K_M text file and the mmproj file
Load the model — LM Studio automatically uses both files

Ollama

ollama run dhptl/qwen3.6-27b

llama.cpp CLI — Text + Image

bash

# Download both files to the same directory, then:
./llama-llava-cli \
  -m Qwen3.6-27B-Q4_K_M.gguf \
  --mmproj Qwen3.6-27B-mmproj-f16.gguf \
  --image /path/to/your/image.jpg \
  -p "Describe this image in detail." \
  -n 512

llama.cpp CLI — Text only (no image)

bash

./llama-cli \
  -m Qwen3.6-27B-Q4_K_M.gguf \
  -p "You are a helpful assistant." \
  --conversation

Python — llama-cpp-python

python

from llama_cpp import Llama
from llama_cpp.llama_chat_format import Llava16ChatHandler

# Load VLM with mmproj
chat_handler = Llava16ChatHandler(clip_model_path="./Qwen3.6-27B-mmproj-f16.gguf")
llm = Llama(
    model_path="./Qwen3.6-27B-Q4_K_M.gguf",
    chat_handler=chat_handler,
    n_gpu_layers=-1,
    n_ctx=4096,
    logits_all=True,
)

# Text + image inference
response = llm.create_chat_completion(
    messages=[
        {
            "role": "user",
            "content": [
                {"type": "image_url", "image_url": {"url": "https://example.com/image.jpg"}},
                {"type": "text",      "text":      "What do you see in this image?"}
            ]
        }
    ]
)
print(response["choices"][0]["message"]["content"])

🔍 VLM Architecture

This model uses a two-component architecture:

Component	File	Purpose
Text Backbone	`Qwen3.6-27B-Q4_K_M.gguf`	Language understanding & generation
Vision Encoder (mmproj)	`Qwen3.6-27B-mmproj-f16.gguf`	Image feature extraction (always F16)

Why is mmproj always F16? The vision encoder maps image pixels to token embeddings. Quantizing it causes visible visual artifacts and degraded image understanding. It stays at F16 (half precision) which is already very efficient at ~1-2GB for most models.
