Let's clarify right away - the counting system was not invented by us - it is common to everyone.
Taken into account:
Entered text.
The response generated by the ChatGPT.
Also, earlier messages used by the neural network for self-learning and response formation are taken into account.
By default, the neural network remembers and processes the last 550 words in a particular chat. The maximum length of a neural network response is about 550 words, this is the limitation of Chat GPT itself.
We remind you that you have the opportunity to turn on the 'Simple' mode, sharply limiting your expenses. This is convenient when you need text on a specific request without serious background and dialogue.
