A quick glimpse of the ChatGPT subreddit (which is not affiliated with OpenAI) shows scathing reviews of GPT-5. Since the model began rolling out, the subreddit has filled with posts calling GPT-5 a "disaster," "horrible," and the "biggest piece of garbage even as a paid user."

Sam Altman, CEO of OpenAI, expressed concerns about the self-destructive use of AI by some ChatGPT users, especially those mentally fragile. He highlighted the responsibility of introducing new technology and the significant attachments users develop towards specific AI models.

OpenAI CEO Sam Altman agreed that it is not as smart as the company claimed earlier. As a result, Altman has decided to bring back the GPT-4o.
