Information about stopping GPT-4o has been announced by OpenAI since January on the company's website. This change also caused many other models to be removed from ChatGPT, including GPT-5, GPT-4.1, GPT-4.1 mini and OpenAI o4-mini.
Previously, in August last year, OpenAI once dismissed GPT-4o to prioritize the GPT-5 model. However, due to many user objections, the company allowed GPT-4o to operate again, although it did not commit to long-term maintenance.
This time, OpenAI shows no intention to keep GPT-4o anymore, because the remaining user base is very small. According to OpenAI, most users have switched to GPT-5. 2, while only about 0.1% of users still choose GPT-4o every day. In addition, OpenAI is also facing many serious lawsuits, including lawsuits directly related to GPT-4o.
Although it was announced two weeks in advance, the suspension of GPT-4o still made many users regretful. On forums, some people called on OpenAI to open the GPT-4o source code, while others expressed disappointment at the loss of the AI model that had been associated with them for a long time.
The official suspension of GPT-4o shows that OpenAI is accelerating the process of streamlining the model system, focusing resources on newer and more widely used versions.
