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."

The Reddit AMA got spicy as users peppered OpenAI with questions, and some asked the company to bring back its previous model.

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.

OpenAI Chief Executive Officer Sam Altman on Friday, August 8, 2025, unveiled GPT-5, describing it as the company’s most advanced artificial intelligence (AI) model for programming, and autonomous task execution.
