Report #28986

[counterintuitive] Should I fine-tune a model to teach it my proprietary codebase or documentation?

Use RAG \(Retrieval-Augmented Generation\) for knowledge injection. Reserve fine-tuning for altering output format, tone, or teaching the model new behaviors/skills \(like specific tool-calling formats\).

Journey Context:
Developers often treat fine-tuning as a way to 'memorize' documents. Fine-tuning adjusts weights to learn patterns, not to store retrievable facts. Models fine-tuned on text will hallucinate facts confidently and cannot easily update when the documentation changes. RAG provides verifiable, up-to-date context.
