Transforming NLP Tasks into Text Generation with LLMs

A company wants to build a system that automatically summarizes long business reports. They are evaluating two different architectural approaches that both use a powerful language model.

Approach A: The system feeds the full report into the language model with the direct instruction, 'Create a one-paragraph summary of the following report.' The model's text output is used as the final summary.

Approach B: The system first breaks the report into sentences. It then uses the language model to calculate an 'importance score' for each sentence. Finally, a separate algorithm selects the top-scoring sentences and combines them to form the summary.

Which approach exemplifies the modern paradigm where the language model acts as a complete, standalone system, and why?
