HydraHead: From Head-Level Functional Heterogeneity to Specialized Attention Hybridization (from the Qwen team)
The quadratic complexity of attention poses a critical bottleneck for long-context processing, spurring interest in hybrid attention designs. Most open-source hybrid models adopt a layer-wise strategy. Yet, prior work has noted the inherent difficulty of integrating Linear Attention (LA) with Full Attention (FA), sugge
