Evaluating Long-Context Model Performance

A research lab announces a new language model capable of processing a 1 million token context window. They claim this breakthrough effectively solves the long-context challenge. Which of the following questions represents the most critical issue to investigate when evaluating the model's true long-context understanding, beyond just its capacity to accept long inputs?

A software development team is building two new AI-powered features. Feature A summarizes lengthy technical specification documents into a one-page executive brief. Feature B allows developers to ask specific questions about a large codebase, such as 'Where is the variable user_session_id defined and modified?'. Given a fixed budget, which feature is more likely to justify the higher cost of a model with an exceptionally large context window, and why?
