Qwen3.8-27B-FP8 — GGUF Quantizations (VLM)




Quantized GGUF versions of Qwen/Qwen3.8-27B-FP8

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

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

Quantized by DhruvalLabs on August 28, 2026 using quant-kit

</div>

---

> [!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 |

|---|---|---|---|---|---|

| Qwen3.8-27B-FP8-Q4_K_M.gguf | 0.01 GB | ~1.5 GB | Q4_K_M ✅ Recommended | ⭐⭐⭐⭐ | Best balance of size and quality. Recommended for most users. |

| Qwen3.8-27B-FP8-Q5_K_M.gguf | 0.01 GB | ~1.5 GB | Q5_K_M | ⭐⭐⭐⭐½ | Better quality than Q4, slightly larger. Great if you have the RAM. |

| Qwen3.8-27B-FP8-Q8_0.gguf | 0.01 GB | ~1.5 GB | Q8_0 | ⭐⭐⭐⭐⭐ | Closest to original quality. Use when RAM is not a concern. |

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

| Filename | Size | Notes |

|---|---|---|

| Qwen3.8-27B-FP8-mmproj-f16.gguf | 0.00 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)

1. Search for DhruvalLabs/Qwen3.8-27B-FP8 in LM Studio
2. Download the Q4_K_M text file and the mmproj file
3. Load the model — LM Studio automatically uses both files

Ollama

ollama run dhruvallabs/qwen3.8-27b-fp8

llama.cpp CLI — Text + Image

# Download both files to the same directory, then:
./llama-llava-cli \
  -m Qwen3.8-27B-FP8-Q4_K_M.gguf \
  --mmproj Qwen3.8-27B-FP8-mmproj-f16.gguf \
  --image /path/to/your/image.jpg \
  -p "Describe this image in detail." \
  -n 512

llama.cpp CLI — Text only (no image)

./llama-cli \
  -m Qwen3.8-27B-FP8-Q4_K_M.gguf \
  -p "You are a helpful assistant." \
  --conversation

Python — llama-cpp-python

from llama_cpp import Llama
from llama_cpp.llama_chat_format import Llava16ChatHandler

# Load VLM with mmproj
chat_handler = Llava16ChatHandler(clip_model_path="./Qwen3.8-27B-FP8-mmproj-f16.gguf")
llm = Llama(
    model_path="./Qwen3.8-27B-FP8-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 | Qwen3.8-27B-FP8-Q4_K_M.gguf | Language understanding & generation |

| Vision Encoder (mmproj) | Qwen3.8-27B-FP8-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.
