About
SpargeAttn is an open-source, training-free sparse attention mechanism designed to significantly accelerate model inference across various AI applications, including language, image, and video models. It provides plug-and-play APIs, such as `spas_sage2_attn_meansim_topk_cuda`, allowing users to easily integrate it by replacing standard attention functions. Users can customize the `topk` parameter to balance attention accuracy with sparsity, or define block-sparse masks for fine-grained control. The tool is built on SageAttention2++ and supports high acceleration on various GPUs, including H100, making it a valuable resource for developers and researchers looking to optimize AI model performance.
