[cost\_intel] Fine-tuning a model to adopt a specific brand voice or output format

Use few-shot prompting with frontier models for style/tone; fine-tune small models only for highly structured task routing or format adherence where few-shot token bloat becomes too expensive.

Journey Context:
Fine-tuning is often used to change tone, but prompting is vastly superior and cheaper for this. Fine-tuning shines when you need to compress a 1000-token few-shot prompt into a 0-shot fine-tuned model, allowing you to use a 10x cheaper model at scale. The ROI crossover is typically >10k calls/day.
