OpenAI Retires GPT-4o and Several Legacy Models
On February 13, OpenAI officially retired GPT-4o, GPT-4.1, GPT-4.1 mini, o4-mini, and GPT-5 Instant/Thinking from ChatGPT.
The move triggered significant user backlash, with thousands of users mourning GPT-4o warm, emotionally resonant conversational style.
An entire subreddit community, r/4oforever, formed in protest. OpenAI noted only 0.1% of users still selected GPT-4o daily, with GPT-5.2 handling the vast majority of traffic.
The company said feedback from GPT-4o fans shaped improvements to personality and creativity in GPT-5.1 and GPT-5.2. API access remains unchanged for now.
