🪄 Simple Definition:
Adjusting a pre-trained AI model with new, smaller sets of data to make it perform better for a specific task.
🌟 Expanded Definition:
Fine-tuning is the process of taking a large, general-purpose AI model and continuing its training with domain-specific data. This allows the model to adapt to specialized use cases (like legal, medical, or retail applications) without retraining from scratch. It’s cost-effective, faster, and delivers more relevant outputs.
⚡ In Action:
A healthcare startup fine-tunes a general language model with anonymized clinical notes so the AI can generate patient summaries that use the right medical terminology.
💡 AIS+ Pro Tip:
Fine-tuning isn’t always the best first step. Start with Prompt Engineering or RAG (Retrieval-Augmented Generation) — then consider fine-tuning when you need highly domain-specific responses.
