Abstract

Large Language Models (LLMs) have achieved remarkable success across a wide range of natural language processing tasks, yet their deployment in real-world systems remains constrained by inefficiencies in training dynamics, domain generalization, and alignment with downstream objectives. This paper proposes a unified optimization framework that integrates multi-objective learning, adaptive knowledge distillation, and distribution-aware fine-tuning to enhance both performance and efficiency of LLMs. The framework jointly optimizes task-specific objectives, representation alignment, and inference efficiency through a coordinated training mechanism. Experimental results demonstrate consistent improvements in accuracy, convergence speed, and robustness across diverse benchmarks, highlighting the effectiveness of the proposed method.
