Hybrid Attention
Mixes cheap linear-attention or state-space layers with a few full-attention layers.
Linear attention variants (Gated DeltaNet, Kimi Delta Attention, Lightning Attention) and state-space layers such as Mamba-2 keep a fixed-size recurrent state instead of a per-token KV cache, so their memory does not grow with context.
Because they are weaker at precise retrieval, hybrids interleave them with a smaller number of full-attention layers, for example three linear layers per full-attention layer in the Qwen pattern.
