Quickstart

uv pip install 'mlx-vlm==0.3.9'

python

from mlx_vlm import load, generate
from mlx_vlm.utils import load_image

model, processor = load("LiquidAI/LFM2.5-VL-450M-MLX-bf16")

image = load_image("photo.jpg")

# Apply chat template (required for LFM2.5-VL)
messages = [{"role": "user", "content": [
    {"type": "image"},
    {"type": "text", "text": "What do you see in this image?"},
]}]
prompt = processor.apply_chat_template(messages, add_generation_prompt=True)

result = generate(
    model,

    [image],
    temp=0.1,
    min_p=0.15,
    repetition_penalty=1.05,
    verbose=True,
)
print(result.text)
