Executive Summary
OpenAI has announced it will retire several older models, including GPT-4o, GPT-4.1, and GPT-4.1 mini, from the ChatGPT interface on February 13, 2026. This decision is driven by the vast majority of users having shifted to the newer GPT-5.2 model, with only 0.1% of daily users still on GPT-4o. The company states that feedback on GPT-4o's popular conversational style and creative capabilities was used to improve the more customizable GPT-5 series, making the older models redundant.
