## Definition

Fine-tuning is the process of further training a pre-trained AI model on a smaller, specialized dataset to adapt its outputs to a specific style, domain, subject, or voice.

## Extended Definition

Foundation AI models are trained on massive general datasets, producing broadly capable but non-specialized outputs. Fine-tuning starts from a pre-trained model and continues training it on a curated dataset representing the target domain. For video generation, fine-tuning can train a model to consistently generate a specific character, visual style, brand aesthetic, or product. For TTS, fine-tuning on voice samples creates a clone of a specific person's voice. For language models, fine-tuning on a creator's past scripts improves stylistic consistency. Fine-tuning requires fewer samples and less compute than training from scratch, making it accessible to individual creators and small teams. The result is a model that generates outputs specialized to the training domain while retaining general capability. In AI video workflows, fine-tuned models enable brand consistency and character continuity across multiple videos.
