Meaning
What Does Fine-Tuning Mean?
Fine-tuning is the process of further training an existing model on specific examples so it performs better for a particular task, style, or domain.
Fine-tuning adapts a model after its original training, often using carefully selected examples related to the intended use.
Fine-tuning adapts an existing model for a more specific purpose. Instead of training from the beginning, developers start with a model that already has broad capabilities and then train it further on selected examples.
Fine-tuning is useful when a team needs consistent output for a defined task. It is not always the right answer. Sometimes better prompts, better retrieval, clearer instructions, or cleaner data solve the problem with less complexity.
