ChatGPT Plus versus pay-per-use
A flat monthly chat subscription is simple, and for a heavy single-model user it can be fair value. But most people are not that user. They want the best model for each task, they use AI in waves, and they would rather pay for what they send. Here is the honest comparison.
What a flat subscription gives you
Access to one vendor's models, with usage caps on the top models that reset over time, plus that vendor's extras. The price is fixed regardless of use, which is comforting and also the point: the median subscriber uses far less than the price would buy per message.
What pay-per-use gives you
Every major model in one place, billed per message at the model's real cost. Routine questions on a fast model cost almost nothing; the expensive reasoning models cost more per message, and you use them only when it matters. There are no caps beyond your balance, and when a better model ships you simply select it.
In Vyndexo the Pro plan is €4 a month with 320 chat credits, the fast chat is included without credits on every paid tier, and premium models draw from credits. Bought credits never expire.
The break-even
If you send hundreds of messages a day to a flagship model, a flat plan may still be cheaper. If you send a few dozen a day, mixed between quick questions and a handful of hard ones, pay-per-use is typically a quarter to a half of the cost, and you get 74 models instead of one family.
