FOR TESTING ONLY

This is an experimental NVFP4 MLX build of Laguna XS 2.1, published for testing purposes only. It has not been validated for quality or correctness and is not an official release. Do not use it in production. For supported checkpoints, see the Laguna XS 2.1 model card and its variants.

Laguna XS 2.1-NVFP4-mlx

Laguna XS 2.1-NVFP4-mlx is an NVFP4 (4-bit) 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

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)
