AWS Certified AI Practitioner AIF-C01 Practice Question
A team plans to fine-tune a publicly available large language model in Amazon SageMaker JumpStart so it can answer questions about the company's product manuals. What rule of thumb should they use to decide whether they have enough training examples to fine-tune the model without overfitting?
Collect 10-50 representative examples and start training immediately.
Accumulate more than 1 million examples so the model relearns the entire domain from scratch.
Gather several hundred to a few thousand diverse examples that cover common queries.
Aim for 50-100 well-crafted examples, then rely on prompt engineering for the rest.
Because the base model already understands general language, fine-tuning focuses on teaching domain specifics. AWS and other industry guidance show that using several hundred to a few thousand diverse, high-quality question-answer pairs usually strikes the right balance-large enough to generalize, yet small enough to train quickly and avoid overfitting. Fewer than about 100 examples often fails to move the needle, and trying to recreate pre-training scale (millions of examples) wastes money. File-size caps are implementation details, not sizing strategy.
