GPT-4o set for retirement as OpenAI shifts focus to newer systems
Legacy AI models including GPT-4o are being withdrawn as OpenAI shifts focus toward newer customised systems.
OpenAI has confirmed that several legacy AI models will be removed from ChatGPT, with GPT-4o scheduled for retirement on 13 February. The decision follows months of debate after the company reinstated the model amid strong user backlash.
Alongside GPT-4o, the models being withdrawn include GPT-5 Instant, GPT-5 Thinking, GPT-4.1, GPT-4.1 mini, and o4-mini. The changes apply only to ChatGPT, while developers will continue to access the models through OpenAI’s API.
GPT-4o had built a loyal following for its natural writing style and emotional awareness, with many users arguing newer models felt less expressive. When OpenAI first attempted to phase it out in 2025, widespread criticism prompted a temporary reversal.
Company data now suggests active use of GPT-4o has dropped to around 0.1% of daily users. OpenAI says features associated with the model have since been integrated into GPT-5.2, including personality tuning and creative response controls.
Despite this, criticism has resurfaced across social platforms, with users questioning usage metrics and highlighting that GPT-4o was no longer prominently accessible. Comments from OpenAI leadership acknowledging recent declines in writing quality have further fuelled concerns about the model’s removal.
