[cost\_intel] Using GPT-4-turbo with 5-shot prompting for repetitive structured classification tasks

Fine-tune GPT-3.5-turbo on >1000 examples for tasks with <500 token output and strict schema adherence \(medical coding, billing classification\); reduces cost 90% with higher accuracy

Journey Context:
Few-shot with frontier models seems cheaper \(no training cost\) but token bloat from examples \(2k tokens/query\) costs $0.06/query. Fine-tuning costs $8-12 training \+ $0.0015/query. At 1k queries, FT is 10x cheaper. Quality improves because model learns implicit rules not in retrieved chunks \(F1 0.91 vs 0.87\).
