How much does ChatGPT cost?

Could you please elaborate on the pricing details of ChatGPT? I'm particularly interested in knowing how much it costs to access and utilize its services. Is there a one-time fee, or does it operate on a subscription basis? Additionally, are there any hidden costs or additional charges that users should be aware of? It would be helpful if you could provide a comprehensive breakdown of the costs associated with ChatGPT, so I can make an informed decision about whether or not it's suitable for my needs and budget.
