Fine-Tuning vs Prompt Engineering
Start with prompt engineering for speed, flexibility, and lower cost, it solves most problems early on. Only move to fine-tuning when you have clear, repeated failure patterns and enough high-quality data to justify it. In production, the best results come from a hybrid approach: measure performance, fix gaps with prompts, and use fine-tuning selectively for stable, high-impact improvements.
