"GPT‑4o, GPT‑4.1, GPT‑4.1 mini, and OpenAI o4-mini are on the way out on February 13, alongside GPT-5 (Instant and Thinking). The retirements apply to ChatGPT. "In the API, there are no changes at this time," the company stated. It isn't the first time OpenAI has attempted to pull the plug on GPT-4o - the model was deprecated last year following the rollout of GPT-5. However, the subsequent outcry resulted in a U-turn, and OpenAI restored both the model and the ability to select it."
"According to OpenAI, users "preferred GPT‑4o's conversational style and warmth," prompting it to tweak subsequent releases. Most usage is now on GPT-5.2, with only 0.1 percent of users choosing GPT-4o each day. After the furor, OpenAI boss Sam Altman said of GPT-4o: "If we ever do deprecate it, we will give plenty of notice." Confirmation of the latest changes is dated January 29, meaning there are two weeks before the model will be pulled from ChatGPT."
