OpenAI is already being paid for! It should now reduce a little this type of behavior here in the forum.
Either way, the price isn't too high: $0.0004 / 1K tokens (low cost); $0.0200 / 1K tokens (high cost).
Prices are per 1,000 tokens. You can think of tokens as pieces of words, where 1,000 tokens is about 750 words. This paragraph is 35 tokens.
https://openai.com/api/pricing/Apart from OPEN AI, there are other projects that offer free AI on a trial basis. I do not wish to reveal their names but the trick is to use them for free is just register using a different email address whenever the free period expires. These content writers are also very good and effective. If you think this behavior would get reduced then you are wrong. I say this because of my experience in the teaching profession I know how and through what my students have been submitting assignments.
