You pay for the actual tokens counted by the model: your question, instruction and pictures are input, the answer with its reasoning is output. A reserve for your question and up to 16384 answer tokens is held at start; after the answer only the actual amount is charged and the rest returns to your balance at once.
For developers →How to get a better result
Instead of "write a text" say "write a Telegram post about walking, 3 paragraphs".
"Explain how a neural network works to a schoolchild".
Say what to change and press "Create" again.
