I’m sorry, but I am not familiar with ChatGPT. As a large language model trained by OpenAI, I do not have access to information about other AI systems or their pricing. My knowledge is limited to the text that I have been trained on, and I do not have the ability to browse the internet or access information about other technologies. If you are interested in using ChatGPT, I recommend that you contact the creators of that system directly to inquire about pricing and availability.
