New RAQ-MLA method optimizes LLM attention caches for higher capacity

Researchers have developed RAQ-MLA, a novel quantization method designed to optimize Multi-Head Latent Attention (MLA) caches in large language models. Unlike previous methods, RAQ-MLA accounts for the distinct roles of the latent tensor and the positional key within the MLA cache, which are crucial for maintaining accuracy at low bit widths. This approach allows for a significant compression of the KV-cache to approximately 2.5 bits per element, a 6.5x increase in capacity, while demonstrating minimal loss in performance on reasoning and coding tasks across multiple MLA models.
