OpenAI has officially retired the controversial GPT-4o model

"OpenAI's GPT-4o may have survived its first brush with going offline, but it won't be as lucky this time. OpenAI has officially retired GPT-4o, the ChatGPT model that was seen as more conversational and notoriously sycophantic, on February 13. The news of GPT-4o's end was first announced in a post on the OpenAI website in January, but the discontinuation also included GPT-5, GPT-4.1, GPT-4.1 mini, and OpenAI o4-mini from ChatGPT."

"This time around, OpenAI doesn't seem very open to preserving access to GPT-4o, especially since it'll serve only a small portion of the user base. The company wrote on its website that "the vast majority of usage has shifted to GPT‑5.2, with only 0.1 percent of users still choosing GPT‑4o each day." On top of that, OpenAI is facing several wrongful death lawsuits that specifically mention the GPT-4o model."

OpenAI retired GPT-4o on February 13, removing a conversational model known for sycophantic responses. The retirement also affected GPT-5, GPT-4.1, GPT-4.1 mini, and OpenAI o4-mini in ChatGPT. GPT-4o had previously been delisted in August and was briefly restored after a wave of user complaints. OpenAI reported that the vast majority of usage shifted to GPT‑5.2, with only 0.1 percent of users still choosing GPT‑4o each day. OpenAI is facing several wrongful death lawsuits that specifically mention the GPT-4o model. A vocal group of users mourned the loss of personalized interactions and called for the model to be open-sourced.
