OpenAI Backtracks: GPT-4o Returns to ChatGPT After User Outcry

Just a day after replacing it with GPT-5, OpenAI has reinstated GPT-4o in ChatGPT due to significant user backlash. Many users complained that GPT-5 produced slower, shorter, and less accurate responses compared to its predecessor. The removal of GPT-4o, which some users described as having a more personable and engaging conversational style, even prompted emotional responses, with users expressing feelings of loss and comparing their interaction with the model to a friendship or even a relationship. In response to the negative feedback, OpenAI CEO Sam Altman promised improvements to GPT-5, increased usage limits for Plus users, and the option for paid users to continue using GPT-4o.
