Frequently Asked Questions

When is fine-tuning worth it?
High query volume + consistent task + acceptable quality with shorter prompts. Rule of thumb: >100K queries/month of the same task type, and you can cut prompt by 50%+, fine-tuning pays back in 2-4 months.
What about inference premium?
Most providers charge slightly more for fine-tuned model inference. OpenAI: about 2-6× base model price. Anthropic: similar. This calculator factors that in.
Alternatives to fine-tuning?
Before fine-tuning: try prompt caching (90% off), few-shot compression, better few-shots, RAG to reduce context, routing easier queries to smaller models. Fine-tuning is powerful but capital-intensive.
