💡 When API beats a subscription: If you don't need the full power of a premium plan — or you want to use several AI models a little each, rather than one model a lot — API access is genuinely the better choice. You pay only for what you actually use, mix the best model for each task, and never pay for idle capacity at the end of the month.
