> Thank you @ioannis . These are my screenshots, I somehow feel that they have made it paid for the new accounts. I found this in the FAQ [ChatGPT API FAQ | OpenAI Help Center](https://help.openai.com/en/articles/7039783-chatgpt-api-faq) The first question has something for free trial users but further below that it says ChatGPT API is not free.

Be sure to also set your repsonse to a text label as well.
