Researchers have developed CACHE-UK, a novel framework designed to improve the stability and factual accuracy of quantized Large Language Models (LLMs) in dynamic financial environments. This system addresses the challenge of catastrophic performance degradation that occurs when sequentially editing LLMs that have undergone 4-bit quantization, a process necessary for efficient deployment. CACHE-UK employs a rank-1 LoRA perturbation mechanism, a financial domain prioritization module, and a Stability Controller to manage "degradation debt" and prevent forgetting. Evaluations on a quantized OpenLLaMA-3B model using a UK financial corpus showed an 11-17% reduction in knowledge degradation and a 6 percentage point improvement in test success rate compared to baseline methods.
