Task-Specific Nature of Scaling Laws
For Large Language Models, achieving a lower test loss during pre-training does not automatically guarantee superior performance across all downstream tasks. Because adapting models for specific applications involves additional steps—such as fine-tuning and prompting—that can significantly influence the final outcome, the scaling laws governing performance may differ in practice depending on the specific downstream task.

Task-Specific Nature of Scaling Laws
A research lab pre-trains two language models, Model Alpha and Model Beta, on the same large text corpus. Model Alpha achieves a final test loss of 1.8, while Model Beta achieves a final test loss of 2.5. However, when both models are later adapted for a specialized legal document summarization task, Model Beta significantly outperforms Model Alpha. Which of the following statements provides the most likely explanation for this discrepancy?

A research lab trains a series of language models, progressively increasing their size and the computational resources used for training. When evaluated on a creative story generation task, performance improves substantially with each increase in model scale. However, when the same models are evaluated on a technical code generation task, performance gains become negligible for the largest models. Which statement best explains this discrepancy?
