QuestionQ76

Core Machine Learning and AI Knowledge

In the context of fine-tuning LLMs, which metric below is most commonly used to evaluate a fine-tuned model’s performance?

  • A Number of layers
  • B Model size
  • C Accuracy on a validation set
  • D Training duration
Explanation

Accuracy measured on a held-out validation set evaluates how well the fine-tuned model generalizes to data not used for training. The number of layers, model size, and training duration are configuration or resource measures rather than direct performance metrics.
