Will GPT 4 become free when gpt 5 releases?

So I am a Chatgpt user for over a year and I am seeing that gpt-4.o is becoming free for everyone but for a limited duration, I wanna ask that whether gpt 4 will become free any soon when gpt 5 releases and what could be the estimate when it will be declared free?

I am pretty sure that you get access to GPT-4o forever, just with strict rate limits.

Yeah but thats what i am trying to say, when will we get access to it with no strict rate limits
