Researchers have developed FibQuant, a novel vector quantization method designed to significantly compress the key-value (KV) cache used in large language models. This technique aims to reduce the memory traffic associated with long-context inference by replacing scalar quantization with a more efficient vector-based approach. Experiments show FibQuant can achieve substantial compression ratios, such as 34x on GPT-2 small KV caches while maintaining high fidelity, and demonstrates improved perplexity compared to existing methods on models like TinyLlama-1.1B.
