Fine-tuning, further education The process of additional training of a ready-made language model on a highly specialized data set. The basic model is run by new examples so that it better understands a particular topic, tone or format.

Fine-tuning is used for corporate chatbots, corporate-style content generation and support automation.

It is important for an SEO professional to understand the difference: fine-tuning changes the behavior of the model through retraining, whereas RAG substitutes relevant data directly into the query.

For GEO-promotion, RAG plays a key role. It determines whose content the model cites in a specific response right now.
