On February 13, 2026, OpenAI will retire several older models, including GPT-4o, GPT-4.1, GPT-4.1 mini, and OpenAI o4-mini from ChatGPT. This decision follows the previously announced retirement of GPT-5. The usage data shows that only 0.1% of users still opt for GPT-4o, indicating a clear shift to the newer GPT-5.2. Feedback from Plus and Pro users influenced this decision, as many expressed a need for more time to transition key use cases due to GPT-4o's unique conversational style and warmth. The retirement aims to streamline focus on the models that most users prefer, especially with improvements seen in GPT-5.1 and GPT-5.2. These updates enhance personality and creativity, addressing user concerns about overly cautious responses. OpenAI is also working on a version of ChatGPT tailored for adults, emphasizing user choice while ensuring appropriate safeguards. The transition away from GPT-4o may be frustrating for some, but OpenAI believes it’s necessary to enhance the overall user experience with the models in active use.
