spicyneuron/Qwen3.5-35B-A3B-MLX-4.9bit-vision

Qwen3.5-35B-A3B optimized for MLX. This quant supports image input and requires a vision-enabled MLX server.

For the non-vision model: https://huggingface.co/spicyneuron/Qwen3.5-35B-A3B-MLX-4.8bit

EDIT: Updated chat template to enable better prompt caching.

Usage

# Start server at http://localhost:8080/chat/completions
uvx --from mlx-vlm --with torchvision \
  mlx_vlm.server \
  --host 127.0.0.1 \
  --port 8080 \
  --model spicyneuron/Qwen3.5-35B-A3B-MLX-4.9bit-vision

Methodology

Quantized using a custom script inspired by Unsloth/AesSedai/ubergarm style mixed-precision GGUFs. MLX quantization options differ than llama.cpp, but the principles are the same:

• Sensitive layers like MoE routing, attention, and output embeddings get higher precision
• More tolerant layers like MoE experts get lower precision
