5-bit (group size 64, 5.636 bits/weight) MLX quantization of deepreinforce-ai/Ornith-1.0-35B, produced with mlx-vlm 0.6.3. Full multimodal: the vision encoder is preserved and quantized alongside the language model. For Apple Silicon. Runs in mlx-vlm or any MLX app.

Conversion note (MoE expert fusion)

Ornith stores its 256 MoE experts unfused (per-expert), but mlx-vlm's qwen3_5_moe loader expects them fused/batched. A sanitize monkeypatch was required to stack the experts before conversion; without it the conversion failed. This is a standard mlx-vlm 5-bit quant.

Usage

bash

uvx --from mlx-vlm mlx_vlm.generate \
  --model mlx-community/Ornith-1.0-35B-5bit --image image.png \
  --prompt "Describe this image." --max-tokens 512

python

from mlx_vlm import load, generate
model, processor = load("mlx-community/Ornith-1.0-35B-5bit")

Conversion check

Smoke-tested after conversion (mlx_vlm.generate on an image): coherent — correctly read an evaluation bar chart, no repetition loop. 107.7 tok/s generation, 987.5 tok/s prompt, peak 26.8 GB on a Macbook Pro M5 Max 128GB 40 GPU.
