Transformers are SSMs (Mamba-2)

Princeton / Carnegie Mellon · 31 May 2024

Proves attention and state space models are two views of structured semiseparable matrices; Mamba-2's SSD layer runs 2-8x faster than Mamba.

The state space duality (SSD) framework lets SSMs use matrix-multiply hardware and lets linear-attention tricks transfer both ways. Mamba-2 became the building block of most hybrids (Jamba-style, Nemotron-H, Zamba) and the base for Gated DeltaNet and Mamba-3.
