Laguna-XS-2.1 (MLX, 6bit)

Converted from poolside/Laguna-XS-2.1 to MLX format, quantized to 6 bits (group size 64, 6.501 bpw effective).

Notes

Works with mlx-vlm and oMLX (forcing the model's vlm mode). mlx-lm doesn't support the laguna architecture yet — there's an open PR: mlx-lm#1223.
Sometimes I got an empty </think> tag at the start of responses, which isn't that common. It won't affect anything tho.

Performance

Measured with oMLX's benchmark harness on a Macbook Pro M5 Max 128GB 40 GPU (single request, 128 generated tokens):
