The fine-tuned model remains private to your account and can be deployed alongside base models.
Best Practices for Effective Customization
To get the most out of fine-tuning:
- Start with a small, high-quality dataset (500–1000 examples).
- Use consistent formatting and clear labels.
- Validate results with a held-out test set.
- A/B test fine-tuned vs base models in production.
Remember: fine-tuning improves performance but doesn’t change the model’s fundamental knowledge. It’s best for style, tone, and task-specific accuracy.
