GPT-4 is a very bad model. It may be initially better than GPT-3.5 for 30 days at most, but it declines rapidly after that. It is worse than GPT-3.5 overall. If this model is used to replace GPT-3.5, it will destroy Open AI.

I've been using ChatGPT for more than 6 months. In the first month, I used GPT-3.5. I encountered various problems with this model like: it was prone to overfitting, it divulges data, it was initially very dumb and only figured out what I was doing after several messages, it doesn't know how to communicate, it couldn't follow instructions. I was very disappointed and thought that this model was the final product.<br><br>During that time, I'd about GPT-4 and started using it. In the first 30 days: it was not prone to overfitting, it doesn't divulge data, it was initially very smart and receptive, it knows how to communicate, it could follow instructions. I was very happy and thought this was it. The model that Open AI was supposed to create.<br><br>After 30 days, GPT-4 started to overfit, it divulges data, it became dumb, it initially misunderstands everything, it doesn't know how to communicate, it couldn't follow instructions. It initially doesn't know how to write. It will say "I'm not good at this". The model became worse than GPT-3.5.<br><br>The worst thing is, you will never be able to use this model for 30 days for the same thing. After that, it will become a stupid model that doesn't know how to communicate. I don't know what they did to GPT-4. Perhaps they used a less advanced training dataset, or perhaps they tried to reduce training costs. I don't know, but this model is bad.<br><br>No one has complained about this issue. I know that I may be the only person who knows about this. But I'm surprised that no one else encountered this issue. This model is bad. It's worse than GPT-3.5. Open AI will go bankrupt with this model.<br><br>I will not pay to use ChatGPT Pro anymore. I already cancelled my subscription. I just want to warn people about this before they waste their money on ChatGPT Pro. If this continues, they will ruin the entire ChatGPT platform.<br><br>If they fix the GPT-4 model, I will pay for ChatGPT Pro and use it. until then, this platform is dead to me.
