Qwen3.5-9B-MLX-4bit#
This is a quantized MLX version of Qwen/Qwen3.5-9B for Apple Silicon.
Model Details#
Original Model: Qwen/Qwen3.5-9B Quantization: 4-bit (~5.059 bits per weight)Group Size: 64Format: MLX SafeTensorsFramework: mlx-vlm
Conversion Details#
This model was converted using mlx-vlm with 4-bit quantization.
Conversion command:
python3 -m mlx_vlm convert \
--hf-path "Qwen/Qwen3.5-9B" \
--mlx-path "./mlx_models/Qwen3.5-9B-MLX-4bit" \
-q --q-bits 4 --q-group-size 64 Copy
Important Note#
A better, more optimized conversion may be available from @Prince (@Blaizzy ) in the MLX VLM community. Check the mlx-community organization for updated versions as official Qwen3.5 support is merged into the main mlx-vlm branch.
Usage#
from mlx_vlm import load, generate
model, processor = load("mlx-community/Qwen3.5-9B-MLX-4bit")
output = generate(
model,
processor,
prompt="Describe this image in detail",
image="path/to/image.jpg",
max_tokens=200
)
print(output) Copy
Or from the command line:
mlx_vlm generate \
--model mlx-community/Qwen3.5-9B-MLX-4bit \
--prompt "Describe this image" \
--image path/to/image.jpg \
--max-tokens 200 Copy
Disk Size: ~5.6 GBRuns efficiently on Apple Silicon Macs (M1/M2/M3/M4) Lower memory footprint compared to 8-bit quantization
