Is GPT-4 free now?

Could you kindly clarify for me? Is the GPT-4 model currently available without any cost? I'm just trying to understand the pricing structure and if it's free for everyone to access or if there are certain conditions or limitations that apply. Thank you for your assistance in this matter. I'm eager to learn more about GPT-4 and its capabilities, but I need to be sure about the financial aspect before proceeding.
