Overview
- GPT-4o, GPT-4.1, GPT-4.1 mini, and o4-mini will be removed from ChatGPT on February 13, alongside previously announced retirements of GPT-5 Instant and GPT-5 Thinking.
- OpenAI says the change is limited to ChatGPT, with no API modifications for now; existing chats and user-created GPTs will switch to GPT-5.2 for new messages, and ChatGPT Voice and image generation continue unchanged.
- The company cites usage data showing only about 0.1% of users choose GPT-4o daily, with the vast majority on GPT-5.2.
- OpenAI says feedback from GPT-4o shaped GPT-5.1/5.2 features, including base styles and controls for warmth and enthusiasm, plus work to reduce unnecessary refusals and to build an adults‑over‑18 experience; age prediction for under‑18 users has rolled out in most markets.
- Some users are disputing OpenAI’s numbers and expressing frustration online, recalling the 2025 rollback after backlash; one outlet also noted lawsuits alleging harms linked to GPT-4o, which OpenAI has not addressed in the retirement rationale.
