FAQ

Does a custom LLM regression suite ever make financial sense for a pre‑Series A startup? No, unless the model powers a revenue‑critical feature that generates at least $250 k per month; otherwise the $180 k engineering overhead dwarfs the benefit.

Can I reuse an open‑source regression framework without incurring extra cost? Not without adaptation; the OpenAI GPT‑3.5 diff script required 48 GPU‑hours nightly, which translates to $12 k in compute—far beyond a typical seed budget.

What is the minimum ROI I should demonstrate to get CFO approval? Aim for a $1 : 4 ratio—spend $12 k per month and show a projected $48 k reduction in churn or a $150 k lift in revenue within the next two quarters.
