OpenAI notified developers on October 14, 2026 that GPT-4o, GPT-4o mini, GPT-4.1 and GPT-4.1 mini will be removed from the API on January 14, 2027, with gpt-6-luna listed as the recommended replacement; fine-tuned versions follow the same schedule. The #keep4o community has launched a Change.org petition urging OpenAI to keep API access, offer a legacy-model subscription, or release GPT-4o as open weights — the petition has drawn hundreds of media mentions and over a thousand comments from fans who consider GPT-4o irreplaceable.
