美团发布支持1M token上下文的LongCat-Flash-Lite-Sparse

作者 PulseAugur 编辑部 · [3 个来源] ·

美团发布了LongCat-Flash-Lite-Sparse，一个基于LongCat-Flash-Lite构建的新语言模型。这个稀疏模型用LongCat Sparse Attention替换了稠密的MLA，并支持高达100万token的上下文长度，远超其前身256k token的限制。该模型拥有约30亿活跃参数，并利用一个卸载到RAM的300亿n-gram查找表，以便在消费级硬件上高效处理长上下文。 AI

影响 能够处理显著更长的文档和对话，可能影响需要深度上下文理解的应用。
