Key Points
- Fine-tuning BERT models in NLP is an important step that contributes to energy use and emissions.
- Pre-training BERT draws more energy than fine-tuning, but fine-tuning is performed more frequently by individual actors.
- The number of training tokens is a reasonable heuristic for estimating fine-tuning energy use.
- Sequence length has a stronger influence on energy intensity in the fine-tuning phase compared to inference.
- Fine-tuning energy efficiency should be studied separately from pre-training and inference workloads in NLP models.

This study focuses on the energy and carbon footprint of fine-tuning BERT models in natural language processing (NLP). While previous research has primarily examined the energy costs of pre-training language models, fine-tuning is a crucial step that must be considered. The authors perform an empirical study to quantify the energy requirements of fine-tuning across various tasks, datasets, and hardware settings. They compare fine-tuning energy use to pre-training and inference and provide recommendations for improving fine-tuning energy efficiency.
The authors note that the typical NLP model lifecycle includes data ingestion, pre-training, fine-tuning, and inference, all of which contribute to energy use and emissions. However, there is a lack of data quantifying the relative contributions of each phase. To address this gap, the authors conduct experiments to isolate the factors that influence fine-tuning dynamics. They compare fine-tuning energy use across different datasets, tasks, and hardware setups and measure energy consumption using CodeCarbon software and physical energy meters.
The results show that pre-training BERT draws substantially more energy than fine-tuning. However, fine-tuning is performed more frequently by many individual actors, making it important to account for its energy and carbon footprint. The study finds that pre-training BERT is equivalent to multiple fine-tuning runs depending on the dataset size. The number of training tokens is a reasonable heuristic for estimating fine-tuning energy use. The study also shows that sequence length has a stronger influence on energy intensity in the fine-tuning phase compared to inference.
The authors emphasize the need to study fine-tuning energy efficiency separately from pre-training and inference workloads in NLP models. They hope that their findings will inform decision-making within and beyond the NLP community. The study concludes with limitations, such as the focus on specific tasks and architectures, and ethical considerations regarding the carbon emissions generated during the experiments.
Overall, this study provides valuable insights into the energy and carbon considerations of fine-tuning BERT models in NLP. The empirical study sheds light on the factors influencing fine-tuning energy requirements and emphasizes the importance of studying fine-tuning energy efficiency. The recommendations provided can guide researchers and practitioners in improving the energy efficiency of their fine-tuning processes.
