OpenAI retires GPT-4o and older models from ChatGPT

OpenAI announces that GPT-4o, GPT-4.1, GPT-4.1 mini and o4-mini will be removed from ChatGPT on February 13, 2026. The API is not affected by the change, and GPT-5 variants are being retired at the same time.

WHY IT MATTERS

This is a normal part of OpenAI's model cycle where older generations are phased out as new models become standard. For ChatGPT users, it means upgrading to newer models, while the APIs remain stable.
