Following the rollout of OpenAI’s latest GPT-5 model earlier this week, a certain user base was adamantly calling for the return of the previous GPT-4o model. Outspoken users complained about the writing quality of the updated model, with some even going so far as to grieve the loss of GPT-4o, which some said they considered a friend and confidant.
In the latest OpenAI update that labels GPT-5 as the “smartest, fastest, most useful model yet,” the company removed the option to choose which model to use and defaults to GPT-5 instead. With the new model, GPT-5 uses a “real-time router” that switches between a more efficient model for basic questions and a deeper reasoning alternative for more complex demands.
The initial rollout ran into some issues that made GPT-5 seem “way dumber,” according to OpenAI’s CEO Sam Altman, who also opened up a Reddit AMA to offer more insight into the changes. On Reddit, Altman responded to a question by saying GPT-5’s writing quality is better than previous models, but asked users if this felt true. In response, several Redditors voiced their opinion that the GPT-5 felt “sterile” and “much worse” and answered “briefly and dryly.” In response to the initial outcry, Altman posted on X that OpenAI would let Plus subscribers choose between using GPT-5 or GPT-4o.
“We for sure underestimated how much some of the things that people like in GPT-4o matter to them, even if GPT-5 performs better in most ways,” Altman said on X.
The return of GPT-4o was celebrated, but there’s still no guarantee that OpenAI will keep its older model around indefinitely. In the same X post, Altman said that OpenAI “will watch usage as we think about how long to offer legacy models for.” In the meantime, OpenAI is focusing on finishing the GPT-5 rollout and making changes that will “make it warmer.” However, for users who have grown attached to GPT-4o as more than just an AI chatbot, this could be the beginning of the end.
