How do I build a simple AI agent with function calling?

Define your tools as JSON schemas, then let the model decide when to call them. Start simple: one tool for search, one for calculation. The model returns a function call instead of text, you execute it, feed results back. Loop until done.

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.
