Guotai Junan: DeepSeek NSA architecture leads AI efficiency revolution, bringing new development opportunities from infrastructure to application layer

Guotai Junan released a research report stating that DeepSeek has launched the NSA (Native Sparse Attention) technology, breaking through the bottleneck of long text processing and promoting the transformation of AI large models towards algorithmic efficiency competition. NSA enhances long text processing efficiency through three parallel attention branches, lowers the development threshold for AI applications, facilitates the popularization of AI technology, and fosters new application scenarios and business model innovations. This technology significantly reduces the computational resources required for pre-training, lowers the threshold for small and medium-sized enterprises to participate in AI development, and brings new market opportunities
