Start the MLX server
# Install MLX LM:
uv tool install mlx-lm
# Start a local OpenAI-compatible server:

GEV-26B-Decide-MLX-8bit

MLX conversion of autotrust/GEV-26B-Decide for mlx-vlm, with the System 1 LoRA merged and the decision head kept in float32. GEV is a decision model: it returns a probability for every option of a question in one forward pass and does not generate text.

GEV support is not yet in an mlx-vlm release:

pip install "git+https://github.com/Lazarus-931/mlx-vlm.git@feat/gev"
from mlx_vlm import load, predict

model, processor = load("nativ-community/GEV-26B-Decide-MLX-8bit")
result = predict(model, processor, "The parcel arrived damaged and I want my money back.", {
    "refund": {"type": "bool", "instructions": "Is the customer asking for a refund?"},
})
print(result["answers"]["refund"]["value"])
