OpenAI to Retire GPT-4o and Other Legacy AI Models in ChatGPT in February
OpenAI announced the retirement date for several legacy artificial intelligence (AI) models in ChatGPT. Most notable in the list is the GPT-4o, which has already survived one sunset attempt. In August 2025, the San Francisco-based AI giant tried to retire the model after introducing GPT-5, but many users protested, highlighting that the newer model lacked the emotional nuance and writing sophistication of the legacy model.
