Google researchers have developed a new technique called TurboQuant that significantly reduces the memory required by large language models. By employing a two-step process involving data rotation and scalar quantization, TurboQuant compresses the KV cache to 3 bits per value, a 6x reduction from the standard 16 bits, without any loss in accuracy. This advancement is crucial for self-hosting LLMs, as the KV cache is a major cost driver for long context windows, and TurboQuant promises to lower infrastructure expenses and improve performance.
