Fine-tuning

İnce ayarlama

D2

Fine-tuning is further training that adapts a pre-trained model for a specific task or domain using task-specific data.

Review status: 2026-11-26

Technical explanation

It follows pre-training and can specialize a broadly trained model for a defined application task, often through supervised learning.

Conceptual boundaries

Fine-tuning further trains a pre-trained model; it is not training from scratch, changing a prompt, or retrieving information at inference time.

Provider-neutral example

A team can further train a pre-trained model on reviewed support categories to specialize it for routing requests in one department.

Limitations

Fine-tuning can affect safety and security controls, so its effects should be evaluated in the intended system context.

    Supported claim
    NIST’s LLM adoption pipeline distinguishes fine-tuning from prompt engineering and from application integration such as RAG.

    Scope limitation
    This distinguishes workflow stages and does not establish a particular outcome from any one stage.
