Nemotron-Mini-4B-Instruct-nvfp4-4bit-mlx

This model was converted from nvidia/Nemotron-Mini-4B-Instruct to MLX format for use on Apple Silicon.

Quantization: 4-bit nvfp4 quantization

Usage

from mlx_lm import load, generate

model, tokenizer = load("mlx-community/Nemotron-Mini-4B-Instruct-nvfp4-4bit-mlx")

prompt = (
    "<extra_id_0>System\n"
    "You are a helpful, honest AI assistant.\n\n"
    "<extra_id_1>User\n"
    "Who are you?\n"
    "<extra_id_1>Assistant\n"
)

print(generate(model, tokenizer, prompt, max_tokens=256))
