Cartesia 发布 Mamba-3:面向推理的状态空间模型
Cartesia 发布 Mamba-3,通过更通用的离散化递归、复值状态空间和 MIMO 并行化提升表达能力,在保持相似推理延迟的同时超越 Mamba-2 和 GDN。内核已开源,1.5B 规模下 SISO 变体在 prefill 和 decode 延迟上优于 Transformer 基线。

obal self-attention layers in the future. at least for language modeling Hybrid models that combine the general memory-like nature of linear layers with the exact database-like storage of self-attention’s KV cache have been shown empirically to outperform pure models while enabling significant memory and compute savings 10, and we do find here that the combination of linear layers with self-attention enables better retrieval compared to a vanilla Transformer. However, we highlight that the exact
