Mamba

What this episode covers

Mamba is a novel deep learning architecture that achieves linear scaling in computation and memory with sequence length, addressing Transformers' quadratic limitations. Its selective State Space Model (SSM) layer dynamically adapts to input context, allowing it to "forget" or "remember" information. Optimizations include a hardware-aware parallel algorithm for its recurrent "selective scan", employing kernel fusion for efficient GPU memory usage and recomputation to reduce memory footprint during training. This results in significantly faster inference (up to 5x throughput) and superior long-context handling.
