Pre-trained model


type: concept tags: [machine-learning, ai, llm, fine-tuning] updated: 2026-04-14

A pre-trained model is a machine learning model trained on a large dataset for a general task (e.g., language understanding), which can be adapted for specific applications through fine-tuning.

  • Efficiency: Avoids training from scratch, saving significant time and computational resources
  • Transfer Learning: Leverages pre-existing knowledge to improve performance on target tasks with limited data
  • Common in LLMs: Most state-of-the-art language models (e.g., GPT, BERT) are pre-trained

Fine-tuning process:

  • Adapts a pre-trained model to a specific task by training on a smaller, task-specific dataset
  • Analogy: Training an experienced chef (pre-trained model) on your restaurant’s recipes (fine-tuning) rather than teaching from scratch
