Should I use GPT-4 or a fine-tuned smaller model?
Use GPT-4 for prototyping and diverse tasks. Fine-tune smaller models when you have consistent, narrow use cases with thousands of examples. Fine-tuned models are cheaper to run but expensive to train and maintain. Start with GPT-4, only fine-tune if cost becomes prohibitive.
When to use this
When making architecture decisions for production AI systems.
When to skip this
For personal use where cost per query isn't a major concern.
