# henrybravo/NVIDIA-Nemotron-3-Nano-30B-A3B-8bit

This model is a clean republish of the verified local 8-bit MLX checkpoint for [nvidia/NVIDIA-Nemotron-3-Nano-30B-A3B-BF16](https://huggingface.co/nvidia/NVIDIA-Nemotron-3-Nano-30B-A3B-BF16).

Source checkpoint:

- original MLX repo: [mlx-community/NVIDIA-Nemotron-3-Nano-30B-A3B-MLX-8Bit](https://huggingface.co/mlx-community/NVIDIA-Nemotron-3-Nano-30B-A3B-MLX-8Bit)
- quantization: 8-bit affine, group size 64
- packaging cleanup: excluded `.cache/huggingface`, `blobs/`, `refs/`, and `snapshots/` from the publish folder because the top-level model assets were already complete
- strict JSON compatibility fix: removed the non-standard `time_step_limit: [0.0, Infinity]` field so `config.json` validates with standard JSON tooling while preserving upstream default behavior
- local validation stack: `mlx==0.31.0`, `mlx-lm==0.31.0`, `transformers==5.3.0`

## Use with mlx

```bash
pip install -U mlx==0.31.0 mlx-lm==0.31.0
```

For OpenAI-compatible local serving and routing on top of MLX models, see [`mlx-router`](https://github.com/henrybravo/mlx-router).

```python
from mlx_lm import load, generate

model, tokenizer = load("henrybravo/NVIDIA-Nemotron-3-Nano-30B-A3B-8bit")

prompt = "hello"

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

response = generate(model, tokenizer, prompt=prompt, verbose=True)
```
