Struct AttentionMasks

Source

pub struct AttentionMasks {
    pub full: Tensor,
    pub sliding: Tensor,
}

Expand description

Additive attention masks: 0 where attention is allowed, -inf elsewhere.

Mirrors upstream’s boolean masks, which MLX’s SDPA turns into exactly this.

Fields§

§full: Tensor

(batch, 1, 1, seq) — key validity.

§sliding: Tensor

(batch, 1, seq, seq) — key validity intersected with the local window.

Implementations§

Source §

impl AttentionMasks

Source

pub fn build( attention_mask: &Tensor, window: usize, dtype: DType, ) -> Result<Self>
