Cartesia and Goomba Lab introduced Mamba-3, a state space model designed with inference efficiency as the primary goal. The model improves upon Mamba-2 through a more expressive recurrence, complex-valued SSM systems, and multi-input multi-output SSMs, aiming to push the quality-efficiency frontier while maintaining similar inference latency.
