# Laguna XS 2.1-NVFP4-mlx

Laguna XS 2.1-NVFP4-mlx is an NVFP4 (4-bit) [MLX](https://github.com/ml-explore/mlx) build of Laguna XS 2.1, a 33B total parameter Mixture-of-Experts model with 3B activated parameters per token designed for agentic coding and long-horizon work on a local machine. It uses Sliding Window Attention with per-head gating in 30 out of 40 layers for fast inference and low KV cache requirements.

## Usage

```python
from pathlib import Path
from mlx_lm import load, generate

MODEL_PATH = "poolside/Laguna-XS-2.1-NVFP4-mlx"

model, tokenizer, config = load(
    MODEL_PATH,
    tokenizer_config={"trust_remote_code": True},
    return_config=True,
)


prompt = "write go code to print the pascal triangle"
response = generate(model, tokenizer, prompt=prompt, verbose=True, max_tokens=256)
```
