OpenAI says Advanced and Standard Voice will leave ChatGPT’s voice model picker on December 11, 2026. Users were notified on November 10 and can continue selecting those modes during the transition.

What changes for existing conversations

People who selected the retiring modes will default to Live voice. OpenAI says existing conversations remain in ChatGPT history and can continue in text or voice; this is a mode transition, not a notice that those conversations will be deleted.

GPT-Live can listen and speak at the same time. Its presence in ChatGPT does not establish a new general-purpose text model, a changed API tariff or a particular model behind every delegated task.

Video has a separate boundary

Live video and screen sharing will continue using Advanced Voice until GPT-Live supports them. OpenAI gives no completion date for that capability in the reviewed notice. December 11 should therefore not be presented as the date all Advanced-powered functions disappear.
