Pricing

ChatGPT with pay-as-you-go

First you buy credit from ChatQT's top-up packages; then each time you use ChatGPT — and any other model if needed — only your actual usage is deducted from that same credit. Pay as you go, instant activation.

All users have access to every capability and available model.

Top-up packages differ only in the amount of credit ; use ChatGPT with that same shared credit — without a separate subscription for each maker.
