Compresses attention state representations into latent vectors using multi-head latent attention (MLA) instead of standard multi-head attention, reducing memory footprint and enabling efficient processing of long contexts (128K tokens). The MLA mechanism projects attention heads into a shared latent space, reducing the KV cache size from O(sequence_length × hidden_dim) to O(sequence_length × latent_dim), where latent_dim << hidden_dim.
