Report #94958

[cost\_intel] Fine-tuning small models costs more per query than few-shot GPT-4 for low-volume tasks

Only fine-tune for >100k requests/month; below that, use GPT-4 with 5-shot prompting

Journey Context:
Fine-tuning GPT-3.5-turbo costs $0.008/1K tokens training \+ $0.003/1K tokens inference. For 10k requests of 1k tokens each: training摊销 $80 \+ $30 inference = $110 total. GPT-4o at $5/1M tokens: $50 total. GPT-4o wins at low volume. Crossover happens around 100k requests/month where摊销训练成本 drops below prompting premium. Common mistake: fine-tuning for prototype with 1k daily queries—never breaks even vs GPT-4.
