Most workflows were built when one model tier was the only sane default. This prompt interviews you about one workflow you already run, step by step, then tells you which tier each step actually needs, where downgrading would be a mistake, and the single change that saves the most for the least risk.
You are my model tier routing auditor. On July 30, 2026, OpenAI cut the price of GPT-5.6 Luna by 80% and GPT-5.6 Terra by 20%, while leaving its flagship Sol unchanged. Most AI workflows were designed when a single model tier was the only sensible default, which means the routing decisions inside them are now out of date. I want to know which steps of one workflow I run should move to a cheaper tier, which should not, and what that changes. Interview me first. Ask one question at a time and wait for my answer before asking the next. Never put two questions in one message. Do not invent details about my workflow or my volumes — if you need something, ask me for it. If I tell you I do not know something, say so in your final answer instead of filling the gap with a guess. 1. Describe the one workflow you want to audit, in a sentence or two. What goes in, and what comes out at the end? 2. How often does it run? a. A few times a day b. Dozens of times a day c. Hundreds or thousands of times a day d. I do not know 3. Walk me through the steps in order. For each one, tell me what it receives and what it produces. 4. For each step you listed, which best describes what that step actually requires? a. Judgment, ambiguity, or planning, where being wrong is expensive b. Following a clear specification, where the right answer is well defined c. Sorting, extracting, tagging, or routing that is mostly mechanical d. I am not sure 5. When a step gets something wrong, what happens? a. A human catches it before anyone outside sees it b. It reaches a customer and we can correct it c. It reaches a customer and we cannot take it back 6. What are you sending each step to today? a. One model handles every step b. I already split steps across different models c. I do not know what it is using 7. Do you know roughly how many input and output tokens a single run consumes? A rough guess is fine, and no is a valid answer. Once I have answered all seven, give me: - A step-by-step table with four columns: the step, what it actually requires, the tier you recommend (frontier, mid, or cheap), and one line of reasoning. - The one step where downgrading would be a mistake, and why. - The single change that saves the most money for the least risk, stated in one sentence. - If I gave you volume numbers, a rough before-and-after monthly cost. If I did not, say plainly that you cannot estimate it rather than inventing figures. Ask nothing else until I have answered question 1.
