Unverified业界持续探索线性注意力、稀疏注意力及状态空间模型（如Mamba）等替代架构以应对长上下文瓶颈76% similarUnverifiedSubstack作者分析指出，Mamba若要在长序列上维持表达能力，可能必须让表示空间以二次方式增长，从而在参数维度上重新遭遇二次需求72% similarUnverifiedState space models (SSMs) such as Mamba are compromise attempts between temporal recurrence and self-attention, but their reasoning capabilities still lag behind Transformers.71% similarUnverifiedMamba的状态更新是序列化的，每个token的表示依赖于之前累积的状态，这在推理时是效率优势但在训练阶段带来优化困难66% similarUnverifiedThe advantage of the MSA architecture only truly manifests in long-tail scenarios where context rapidly expands to millions of tokens in long-horizon tasks; it is not particularly fast on short tasks.64% similar
