Starting February 13, 2026, OpenAI will discontinue GPT-4o, GPT-4.1, GPT-4.1 mini, and OpenAI o4-mini from ChatGPT, in addition to the already scheduled removal of GPT-5 (Instant and Thinking) versions. The API services remain unaffected by these changes.
Understanding the GPT-4o Retirement
GPT-4o has a unique history that requires additional explanation. After initially removing it during the GPT-5 launch and subsequently restoring access, OpenAI gained valuable insights into user preferences and requirements. Plus and Pro subscribers specifically requested additional time to adapt their workflows, particularly for creative brainstorming applications. These users appreciated GPT-4o's conversational approach and warmer interaction style.
The user feedback collected during this period directly influenced the development of GPT-5.1 and GPT-5.2. These newer versions incorporate enhanced personality features, improved creative ideation capabilities, and expanded customization options for response styles. Users can now select from various base styles and tones, including Friendly mode, while adjusting parameters like warmth and enthusiasm levels. OpenAI's objective is to provide users with greater control over the interaction experience, not just the functional capabilities.
OpenAI decided to announce GPT-4o's retirement now because these enhancements are fully implemented, and usage data shows that most users have already transitioned to GPT-5.2. Currently, only 0.1% of daily active users continue to select GPT-4o.
Ongoing Improvements to ChatGPT
OpenAI continues to enhance ChatGPT based on user feedback in several key areas. Upcoming updates will focus on refining personality and creativity features, while also addressing issues with unnecessary content restrictions and overly cautious or moralistic responses. The company is working toward developing an adult-oriented version of ChatGPT for users 18 and older, emphasizing user autonomy and choice within appropriate safety boundaries. To facilitate this, OpenAI has implemented age verification systems for users under 18 in most regions.
OpenAI acknowledges that transitioning from familiar models can be challenging and commits to maintaining transparency about changes and timelines. While some users may find GPT-4o's removal disappointing, the decision was carefully considered. Model retirements, though difficult, enable OpenAI to concentrate resources on enhancing the platforms that serve the majority of their user base.
