CoMerge framework optimizes LLM merging using conflict-driven preference optimization

Researchers have introduced CoMerge, a novel framework for optimizing the merging of multiple large language models (LLMs) without requiring full retraining. This conflict-driven preference optimization approach uses the degradation from naive merging methods as negative samples to refine merging coefficients. Experiments demonstrate that CoMerge significantly outperforms existing model-merging baselines on the MergeBench benchmark and shows marked improvements on sensitive tasks for Llama-3.1-8B-Instruct, all while optimizing a small number of coefficients. AI

IMPACT This research could lead to more efficient creation of multi-task LLMs, reducing the need for extensive retraining and improving performance on specialized tasks.

    CoMerge: Conflict-Driven Preference Optimization for Multi-Task Model Merging

    arXiv:2609.02273v1 Announce Type: new Abstract: Model merging provides an efficient paradigm for constructing multi-task large language models (LLMs) without full model retraining, yet it remains challenged by parameter interference. While existing methods aim to preserve the cap…
