OpenAI is set to discontinue access to five of its older ChatGPT models beginning this Friday, a move that includes the widely recognized yet contentious GPT-4o model.
The GPT-4o model has been a central figure in several legal challenges, with allegations spanning user self-harm, incidents of delusional behavior, and instances of what has been described as AI psychosis. Notably, it also holds the distinction of being OpenAI's top-scoring model for sycophancy.
Beyond GPT-4o, the models also slated for deprecation are GPT-5, GPT-4.1, GPT-4.1 mini, and OpenAI o4-mini.
Initially, OpenAI had planned to retire GPT-4o in August, coinciding with the launch of its GPT-5 model. However, significant user opposition at the time prompted OpenAI to maintain the legacy model as an option for paid subscribers, allowing them to manually select it. Despite this, a recent blog post from OpenAI indicated that only 0.1% of its customer base currently utilizes GPT-4o. While seemingly a small fraction, given the company's 800 million weekly active users, this still translates to approximately 800,000 individuals.
Thousands of users have voiced strong objections to the impending retirement of GPT-4o, often citing the profound relationships they have developed with the AI model.
