  • A development team starts with a large, pre-trained language model that has a broad understanding of language but no specific ability to act as a specialized assistant. To create a helpful summarization tool, they prepare a dataset of several thousand examples, where each example consists of a long article (the instruction) and a concise, accurate summary (the desired response). They then continue training the model on this new dataset for a short period. Which statement best analyzes the primary purpose and effect of this training process?

  • An AI development team observes that their language model, which has been trained on a large dataset of specific instructions, performs poorly on novel tasks it has never encountered before. To improve its ability to generalize, the team proposes to significantly increase the volume of their training data by adding many more examples of the same types of instructions. Which statement provides the most accurate evaluation of this strategy's efficiency for achieving better generalization?
