OpenAI sets January shutdown date for selected GPT-4 API models
OpenAI’s October 14 deprecation notice schedules selected GPT-4o, GPT-4o mini, GPT-4.1 and GPT-4.1 mini snapshots for removal from the API on January 14, 2027. It lists GPT-6 Luna as the recommended replacement and says fine-tuned versions follow their base models’ shutdown schedule.
Why it matters
Editorial analysis: teams using these snapshots now have a concrete migration deadline. They should identify affected dependencies and evaluate replacement behavior before the shutdown. The notice does not say every GPT-4 variant shares this deadline.
