Is ChatGPT 4 now free?

Hello, I was wondering if you could clarify something for me. The latest version of ChatGPT, specifically ChatGPT 4, has been generating a lot of buzz lately. I've seen some claims that it's now available for free, while others say that's not the case. Could you please shed some light on this matter? Are users now able to access ChatGPT 4 without any cost, or is there still a fee associated with using this advanced AI tool? I'd really appreciate your insight on this topic.
