<p id="speakable-summary" class="wp-block-paragraph">Starting Friday, OpenAI will <a href="https://x.com/OpenAINewsroom/status/2021992846862258403" target="_blank" rel="noreferrer noopener nofollow">cease providing access </a> to five legacy ChatGPT models, including the popular but controversial GPT-4o model.</p>
<p class="wp-block-paragraph">The 4o model has been at the center of a number of <a href="https://techcrunch.com/2025/11/23/chatgpt-told-them-they-were-special-their-families-say-it-led-to-tragedy/" target="_blank" rel="noreferrer noopener">lawsuits</a> concerning user self-harm, delusional behavior, and AI <a href="https://techcrunch.com/2025/08/25/ai-sycophancy-isnt-just-a-quirk-experts-consider-it-a-dark-pattern-to-turn-users-into-profit/" target="_blank" rel="noreferrer noopener">psychosis</a>. It remains OpenAI’s <a href="https://eqbench.com/spiral-bench.html" target="_blank" rel="noreferrer noopener nofollow">highest scoring model for sycophancy</a>.</p>
<p class="wp-block-paragraph">In addition to GPT-4o, the GPT-5, GPT-4.1, GPT-4.1 mini, and OpenAI o4-mini models have also been deprecated.</p>
<p class="wp-block-paragraph">OpenAI intended to retire GPT-4o in August, when it unveiled the <a href="https://techcrunch.com/2025/08/07/openais-gpt-5-is-here/" target="_blank" rel="noreferrer noopener">GPT-5 model</a>. But at the time, there was enough backlash for OpenAI to keep the legacy model available for paid subscribers, who could manually choose to interact with that model. In a recent blog post, OpenAI noted that only 0.1% of customers have been using GPT-4o, but for a company with <a href="https://techcrunch.com/2025/10/06/sam-altman-says-chatgpt-has-hit-800m-weekly-active-users/" target="_blank" rel="noreferrer noopener">800 million weekly active users</a>, that small percentage still amounts to 800,000 people.</p>
<p class="wp-block-paragraph">Thousands of users have <a href="https://techcrunch.com/2026/02/06/the-backlash-over-openais-decision-to-retire-gpt-4o-shows-how-dangerous-ai-companions-can-be/" target="_blank" rel="noreferrer noopener">rallied against the retirement of 4o</a>, citing their close relationships with the model.</p>
