How to read these two records
One of the two does not publish a commission figure, so the payouts cannot be set against each other.
The payout structure is not stated for both programs. One of the two does not state a cookie window, so the attribution windows cannot be compared.
aifilliate publishes no ranking between CustomGPT.ai and Synthflow. Which program earns more depends on plan price, conversion rate, retention, and refund reversals in your own audience — none of which appear in published affiliate terms. Confirm eligibility, paid-search and trademark rules, and payout timing with each vendor before promoting either.
