Multi-Head Latent Attention (MLA) is a novel attention mechanism designed to significantly compress the KV cache in large language models. By projecting KV pairs into a low-dimensional latent space, MLA achieves substantial cache reduction, enabling models like DeepSeek-V2/V3 and Kimi K2.x to handle longer contexts and larger batch sizes with less memory. This technique alters how prefix caching and attention computations are implemented, offering a more efficient trade-off between memory usage and computational cost during model inference. AI
