OpenAI CEO Sam Altman noted that users became accustomed to ChatGPT's overly agreeable nature, leading to backlash against the new GPT-5 update aimed at providing more critical feedback.

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."

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.
