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.

It's not the first time that OpenAI has delisted GPT-4o as an option for ChatGPT. In August, the AI giant sunsetted the GPT-4o model in favor of rolling out and prioritizing the latest GPT-5 model at the time. However, a wave of user complaints led OpenAI to restore access to GPT-4o but with no guarantee that it'll be around forever.
