OpenAI CEO Sam Altman acknowledged a 'bumpy' GPT-5 launch, citing a malfunctioning real-time router that initially hampered the model's performance. Altman addressed user concerns on Reddit, promising improvements to the model's decision-making process and increased transparency.

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."
