Pre-built AI service vs custom model
WHAT IT TESTS: buy-versus-build judgment for ML. OUTLINE: choose a managed service for speed, no ML expertise, and common tasks; build custom for domain-specific needs, control, or cost at scale. RED FLAG: always building custom when a managed API suffices.
WHAT IT TESTS: whether you weigh time, expertise, control, and cost in an ML buy-versus-build decision. ANSWER OUTLINE: choose a pre-built service like Rekognition when the task is common (face or object detection, OCR), you lack training data or ML staff, and you want fast time to market with pay-per-call pricing; build custom when you need domain-specific accuracy, full control over the model and data, predictable cost at very high volume, or features the API lacks. Trade-offs span speed, accuracy fit, cost curve, and data control.
