Where do you buy ChatGPT?

I've been hearing a lot about ChatGPT recently, and it seems like a fascinating piece of technology. However, I'm having some difficulty finding a reliable source to purchase or access it. Could you please enlighten me on where one might go to buy ChatGPT? I've tried searching online but the information is quite scattered and often contradictory. I'm hoping to get a clear and concise answer from someone who is knowledgeable in this field. Thank you for your time and assistance in this matter.
