OpenAI will retire several models, including GPT-4o, from ChatGPT next month

OpenAI announced it will retire several models from its ChatGPT chatbot next month, including its GPT‑4o model that is beloved by some users.

The artificial intelligence startup launched GPT-4o in May 2024, and its warm conversation style was extremely popular with a subset of its paid users. The company faced backlash in August after it briefly removed access to GPT-4o following the launch of a newer model, GPT-5.

OpenAI swiftly restored access to GPT-4o for paid users, and CEO Sam Altman pledged to give “plenty of notice” if the company ever decided to retire it, according to a post on X in August.

Now, it seems that day is fast approaching.

“We know that losing access to GPT‑4o will feel frustrating for some users, and we didn’t make this decision lightly,” OpenAI said in a blog post Thursday. “Retiring models is never easy, but it allows us to focus on improving the models most people use today.”
