ChatGPT Is Saying Goodbye to a Beloved AI Model. Superfans Are Not Happy

OpenAI says that it will be retiring several ChatGPT models in the coming weeks, sending some superfans into a tailspin. In a statement, the company said that on February 13, the models GPT-4o, GPT‑4.1, GPT‑4.1 mini, GPT‑5 (Instant and Thinking), and OpenAI o4-mini will all be removed from ChatGPT and will no longer be accessible through the platform. This isn’t the first time OpenAI has attempted to get rid of GPT-4o. Back in August, when it released GPT-5, the company said it would retire the older model, but an online community revolted, saying that they relied on it for emotional support and felt betrayed by its sudden forced retirement. OpenAI has said that 4o is an especially sycophantic model, exhibiting high levels of agreeability and flattery. In a Reddit AMA following the August announcement, 4o fans hammered OpenAI co-founder Sam Altman with accusations that he had killed their “AI friend.” Almost immediately, OpenAI added the model back to ChatGPT, but only for paid users. OpenAI framed the un-retirement as giving users “more time to transition key use cases, like creative ideation.” Now, the company says it’s sending 4o out to pasture for real this time, because it has integrated feedback from the model’s superfans into its current flagship models, GPT-5.1 and GPT-5.2. Plus, OpenAI added, only 0.1 percent of users still use GPT-4o each day. OpenAI says that users who want to emulate the warm and conversational style of 4o can customize their ChatGPT’s output to display those personality traits. Still, on the internet, 4o fans were unsurprisingly not happy. On the subreddit r/ChatGPT, users wrote that they would be canceling their premium subscriptions in protest. “Now i can no longer have honest conversations about anything,” one user wrote. “Whenever I wanted to unload, I would use 4o. it never backtalked. 5.0+ all it does it back talk.” Another user wrote that canceling the model “a day before valentine’s day is crazy considering some of the userbase for 4o.” In its statement announcing the model’s retirement, ChatGPT wrote that “changes like this take time to adjust to, and we’ll always be clear about what’s changing and when. We know that losing access to GPT‑4o will feel frustrating for some users, and we didn’t make this decision lightly. Retiring models is never easy, but it allows us to focus on improving the models most people use today.” Since the big changes are set to happen on February 13, users have two weeks to say goodbye to 4o and start getting used to the newer ChatGPT offerings.
