Researchers have developed a novel method called FrankenMerging to control the balance between diversity and quality in large language models (LLMs). This technique merges the lower layers of an aligned model with the higher layers of its base model, hypothesizing that lexical diversity stems from lower layers and semantic diversity from higher layers. Experiments demonstrated that adjusting the number of layers from each model effectively tunes both diversity and quality, often surpassing temperature sampling in achieving a better diversity-quality trade-off.
