This model was converted using mlx-vlm from the pc/fix-qwen35-predicate branch, which includes fixes for Qwen3.5 model support (proper handling of MoE gate layers, shared_expert_gate, and A_log casting).

Conversion command:

bash

python3 -m mlx_vlm convert \
  --hf-path "Qwen/Qwen3.5-9B" \
  --mlx-path "./mlx_models/Qwen3.5-9B-MLX-bf16"

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.
