Consider two different applications for a large language model:

1. An interactive customer service chatbot for a global airline, expected to handle thousands of conversations simultaneously with near-instantaneous replies.
2. A research tool for a scientific institute that processes large batches of experimental data overnight to generate detailed summary reports, with results needed by the next morning.

Analyze the primary performance challenges for deploying the model in each scenario. Contrast how the operational priorities for the system would differ, specifically regarding the need to serve many users at once versus the need for rapid individual response times.
