This model mlx-community/NVIDIA-Nemotron-3.5-Lightning-30B-A3B-4bit was converted to MLX format from nvidia/NVIDIA-Nemotron-3.5-Lightning-30B-A3B-BF16 using mlx-lm version 0.31.3 (4-bit, group size 64).
NVIDIA-Nemotron-3.5-Lightning-30B-A3B is a hybrid Mamba-2 / attention Mixture-of-Experts model (~31B total parameters, ~3B active per token).
Use with mlx#

if tokenizer.chat_template is not None:
messages = [{"role": "user", "content": prompt}]
prompt = tokenizer.apply_chat_template(
messages, add_generation_prompt=True
)
