OpenAI Sets Date to Pull GPT 4o From ChatGPT

OpenAI said it will retire several models from ChatGPT next month, including GPT‑4o, the model some paid users favored for its warm conversation style. The company launched GPT‑4o in May 2024 and faced backlash in August after briefly removing access following the release of GPT‑5, then restoring it and promising advance notice before any permanent retirement. OpenAI now says only 0.1% of users choose GPT‑4o daily and most people use GPT‑5.2, citing recent upgrades to personality, customization, and creative ideation. GPT‑4.1, GPT‑4.1 mini, and o4-mini will also exit ChatGPT. The API stays unchanged.
