After GPT-5 backlash, Sam Altman confirms GPT-4o is coming back to ChatGPT — but there’s a catch

OpenAI’s much-hyped GPT-5 model launched on Thursday, but unlike what the ChatGPT maker would have expected, its latest and greatest model was met with a lot of scrutiny on social media, with longtime users of the chatbot unhappy with the company over the removal of older OpenAI models like GPT-4o and GPT-4.1. Notably, after the launch of GPT-5, OpenAI stopped supporting the older models and GPT-5 became the default model for all tasks, leading to widespread frustration on social media.

OpenAI has claimed marked improvements in the performance of ChatGPT with GPT-5, including reasoning, coding, accuracy, multimodal understanding, writing, and answering health-related questions.
