A team fine-tunes a pre-trained language model on a dataset consisting of 50,000 examples. Every example in the dataset follows the same format: an instruction to 'Summarize the following article,' followed by a long news article and a professionally written one-paragraph summary. After training, the model is tested with a new instruction: 'Summarize the following article,' followed by a news article it has never seen before. Which outcome would best demonstrate that the model has successfully generalized from its training?
