Researchers at EleutherAI explored the impact of fine-tuning the GPT-Neo 2.7B model on a diverse set of downstream tasks. They observed that while the fine-tuned model did not universally outperform the base model, it showed significant improvements on certain tasks like ANLI. However, this specialization came at the cost of performance degradation on tasks not included in the fine-tuning set, such as LAMBADA and PubMedQA, indicating a potential for catastrophic forgetting.
