# SF grids

The 27 Gaussian VQ codebook grids used by the published SF model maps.

Binary format: `[uint32 n][uint32 d][float64 distortion]` followed by `n*d` float32 centroid values.

Model-specific weight and KV sensitivity maps are published separately as `dlab-cmu/sf-map-<model-name>` and collected in **SF grids and maps**.
