Overview
Fine-tuning is the process of training a pre-trained model on task-specific examples so it behaves more consistently for a defined domain or output format.
Core Components
- curated training dataset with high-quality examples
- clear target behavior and evaluation criteria
- training and validation workflow
- post-training safety and performance checks
Where It Works Best
- strict response format and style control
- domain-specific classification tasks
- workflow prompts with repetitive structured outputs
- high-volume tasks where prompt-only tuning plateaus
Key Design Decisions
- fine-tuning vs prompt engineering vs RAG
- dataset size and label quality requirements
- model selection and cost constraints
- retraining cadence based on drift
Risks and Controls
- training on noisy or biased examples
- overfitting to narrow patterns
- compliance issues with sensitive data in training set
- insufficient evaluation before rollout
Metrics to Track
- task accuracy improvement vs baseline
- format adherence rate
- inference latency and cost impact
- post-launch error trend
