Native Hybrid Attention for Efficient Sequence Modeling
This research introduces Native Hybrid Attention (NHA), a novel architecture that unifies linear and full attention within a single layer design. NHA efficiently handles long-term context via an RNN-updated key-value slot mechanism and short-term context from a sliding window, processing both with a single softmax operation. This approach dynamically assigns attention without extra parameters, improving performance on recall-intensive tasks. NHA's unique design also allows flexible inter-layer hybridization by adjusting window size, seamlessly transitioning between linear RNN and full attention modes without retraining. This offers a scalable and efficient solution for large language models, demonstrated by competitive accuracy and significant inference speed gains over existing Transformer and hybrid architectures.
Executive Impact & ROI
NHA delivers significant efficiency gains and superior performance on complex reasoning tasks, leading to substantial reductions in computational costs and enhanced LLM capabilities for enterprise applications. It offers a more adaptable and scalable architecture for future AI deployments.

Architecture Design
NHA introduces a unified layer design that natively integrates linear (RNN-based memory slots) and sparse (sliding window) attention mechanisms. This design allows for seamless intra-layer hybridization, processing both short-term precise tokens and long-term summarized information through a single, context-dependent softmax. The inter-layer hybridization is controlled by a single hyperparameter (window size), enabling dynamic adjustment from pure linear RNN to full attention without altering the core architecture, unlike prior models that require stacking heterogeneous layers.
Efficiency & Scalability
NHA achieves remarkable efficiency by maintaining near-linear scaling in computational cost and memory usage, significantly outperforming traditional Transformers on long sequences. The chunkwise-parallel Triton kernel further optimizes GPU computation. When applied to pre-trained LLMs, NHA-hybridized models demonstrate competitive accuracy with substantial reductions in inference time and memory, proving its scalability for production-level large language models.
Performance & Robustness
Experimental results show NHA consistently surpasses Transformers and other hybrid baselines on recall-intensive and commonsense reasoning tasks. Its hybrid design preserves strong general reasoning abilities while enhancing efficiency. On long-context benchmarks, NHA exhibits stronger extrapolation capabilities. Ablation studies confirm the critical contributions of both long-term and short-term memory, as well as the superiority of unified softmax fusion over weighted summation.
