Isn't open ai the company that have got 4 then ruined it with got 5

It seems you might be referring to the reception of different versions of the AI model developed by OpenAI, particularly in the context of "GPT-4" and "GPT-5." As of my last knowledge update in October 2023, GPT-4 was well-received for its capabilities, while information about GPT-5 was not publicly available. Generally, the response to new iterations of AI models can vary, with some users favoring the improvements and new features introduced, while others may have concerns or criticisms. If you have specific features or issues in mind regarding these models, feel free to elaborate!
