Static WEIGHTS_BYTES 

static WEIGHTS_BYTES: &[u8]

Bundled sparse-linear projection weights for BGE-M3 sparse embedding.

Provenance

Extracted from the fastembed-rs crate (v4) which bundles the same file from the BAAI/bge-m3 checkpoint. The weights implement the sparse-linear layer described in the BGE-M3 paper: a single linear projection hidden_size → 1 that maps each token’s 1024-d hidden state to a scalar relevance score, followed by ReLU activation and max-pooling by vocab ID.
