Overview
- Starting next month, OpenAI will disable GPT-4o, GPT-4.1, GPT-4.1 mini, and o4-mini from ChatGPT.
- OpenAI said only 0.1% of users choose GPT-4o daily, while most use GPT-5.2, a usage pattern it cited for the decision.
- GPT-5 Instant and GPT-5 Thinking had already been slated for removal, signaling further simplification of the model lineup.
- CEO Sam Altman acknowledged complaints that GPT-5.2’s writing quality declined and said the team prioritized reasoning, programming, and tool use over expression.
- OpenAI said recent work improved personalization and creativity, and it noted it would provide advance notice after last year’s brief pause of GPT-4o access.
