Sell Your Custom GPT and Get Paid Per Run

You cannot really sell a custom GPT. Inside the GPT Store you can share it, but there is no clean way to charge per use, and anyone can extract the instructions behind it. The better move is to stop selling the GPT and start selling the outcome it produces — packaged as a hidden workflow you get paid for on every run. Here is how that works, plainly.

Why "selling a custom GPT" does not work

A custom GPT has two problems as a product:

• You cannot charge per use. The store never gave most builders real per-run income, so all that usage earns you nothing.
• It leaks. A shared GPT can be prompt-extracted. The first buyer can read your instructions and rebuild it — so even if you sold it once, your method is now public.

You end up with the worst of both: no recurring revenue and no protection for the method you spent time building.

Sell the result, get paid per run

A workflow packages your GPT's method as a button. The buyer answers a few questions, your prompt chain runs on a server, and they get the finished result. On MyGPTList that means:

• You set your earning per run and keep 100% of it. Every successful run pays you — it is a metered asset, not a one-time sale.
• Buyers pay one fixed upfront price. They see the exact credit price before they run (1 credit = $0.10). No per-message meter, no subscription.
• Failed runs auto-refund. If a run fails on our side, the buyer's credits are released and you are not charged.
• Your prompt stays hidden. It runs server-side and is never shown to the buyer, so it cannot be copied like a shared custom GPT.

That is the difference between selling your know-how once and getting paid for it every time it runs.

What you actually keep

You choose an earning per run — for example $2. The platform adds the AI cost, a small fee, and a risk buffer to set one fixed buyer price in credits, and you keep 100% of your $2 on each successful run. Because failed runs auto-refund, you are not paid for bad results and buyers are not charged for them — which keeps trust high and refunds low.

Plug your number into the Creator Earnings Calculator to see your take-home and the resulting buyer price before you commit. If you are weighing this against a prompt pack, the math in prompts vs workflows shows why a per-run asset wins over time.

From custom GPT to paid workflow

Three steps, no code:

1. Recreate your GPT's intake — the questions that make the output good.
2. Encode the method as the hidden prompt chain — the same packaging process that keeps your IP private.
3. Set your earning, publish, and share one link with the audience you already built.

Ship it and start earning

The GPT you already built is the hard part. Turn its method into a workflow that earns on every run: start on the GPT builders page, price your first one with the Creator Earnings Calculator, or apply for the Founding 100 for early access and founding-only perks.
