Fine-Tuning

Definition

Fine-tuning is further training a base AI model on your own domain data so it performs better on your specific tasks, tone, and terminology.
Summarize with AI:ChatGPTClaudePerplexity
Last updated June 2026

Key points

  • Changes how the model behaves; RAG changes what it knows. They're often combined.
  • A small model fine-tuned for your domain can outperform a large general one.
  • Builds a proprietary asset competitors can't easily replicate.

Quick answer

Fine-Tuning, common question

If your need is current, citable knowledge, RAG is usually enough. If you need consistent domain behavior, format, or specialized performance, fine-tuning helps, and the two work well together.
