Not all Transformer models are called “large language models” because you can build a very small model using the Transformer architecture. The truly large Transformer models are often impractical to use at home because they’re too large to fit on a single computer and too slow to run without a cluster of GPUs. The recent introduction of Multi-Head Latent Attention (MLA) proposed a new approach to running attention operations with a lower memory footprint. First proposed in DeepSeek-V2, it changes how you perform matrix multiplication in the attention operation. In this post, you will learn how MLA works and how to implement it in PyTorch. Kick-start your project with my book Building Transformer Models From Scratch with PyTorch. It provides self-study tutorials with working code. Let’s get started.
