Correct answers: A, B, D, E
Explanation
To ensure a multimodal generative AI model remains scalable, performant, and reliable, it's important to systematically evaluate performance bottlenecks and resource usage. Steps like analyzing memory usage, optimizing batch size, profiling the performance pipeline, and benchmarking latency and throughput are critical in identifying and resolving issues. Abruptly switching architectures without consultation is not a practical or supervised approach to addressing the problem.
- A. Correct.
Analyzing memory usage is essential to ensure the system is not running into resource limitations that can cause slowdowns during inference, a critical step in evaluating performance issues.
- B. Correct.
Optimizing batch size can significantly improve inference speed without compromising memory efficiency, which is a key consideration for scalability.
- C. Incorrect.
Switching to a new model architecture without consultation is not an appropriate step for troubleshooting; it disregards the structured process of supervised deployment and evaluation.
- D. Correct.
Using a profiling tool helps pinpoint the exact performance bottlenecks, such as computation-heavy layers or I/O delays, making it a vital step for improving scalability and performance.
- E. Correct.
Evaluating latency and throughput on a standardized dataset provides insights into the model's real-world performance and helps in identifying areas for optimization.
