OpenAI is retiring Advanced and Standard voice from ChatGPT Voice on December 11, 2026, according to its ChatGPT release notes dated November 10. OpenAI says users who had either selected will be defaulted to Live voice, which runs on GPT-Live, the model it introduced in July.
By our arithmetic, that is 31 days between the notice and the switch-off, and it removes two of the three voice options OpenAI’s Help Center names: Live, Advanced and Standard.

The key insight:OpenAI is retiring Advanced and Standard voice from ChatGPT Voice on December 11, 2026, according to its November 10 release notes. By our arithmetic, that is 31 days of notice and two of the three voice options its Help Center names. OpenAI says virtually all voice users already use GPT-Live.
OpenAI says “voice usage has nearly doubled, and virtually all people using voice in ChatGPT now use GPT-Live” since the July launch. It says the change will let it “simplify the voice experience and focus on improving GPT-Live”.
The Help Center timeline gives three steps: users were notified on November 10, they can keep using Advanced or Standard voice during the transition, and from December 11 the two options disappear from the model picker in Settings > Voice. Conversations stay in ChatGPT history and can be continued in text or voice.
Two exceptions are listed. “Live video and screen-sharing will continue to be powered by Advanced voice until GPT-Live has this capability”, and “Voice with custom GPTs will continue using Advanced voice until their deprecation on December 11, 2026”, the same date OpenAI gives in its voice FAQ.
The three ChatGPT voice options as OpenAI’s Help Center describes them, and what happens to each on December 11, 2026. The 31 days of notice is our arithmetic.
What Was Posted on X
Weโre retiring Advanced and Standard voice from ChatGPT Voice on December 11, 2026.
In July, we introduced GPT-Live, our latest voice model that combines natural conversation with frontier intelligence. Since then, voice usage has nearly doubled, and virtually all people using voice in ChatGPT now use GPT-Live. This change will allow us to simplify the voice experience and focus on improving GPT-Live.
We’ve learned a lot from how people used both Advanced and Standard voice, and we’re bringing those learnings into GPT-Live as we continue to improve areas like the depth and detail of responses, maintaining continuity across conversations, and better personalization. Our ultimate goal is to make voice a seamless part of the ChatGPT experience.
Live video and screen-sharing will continue to be powered by Advanced voice until GPT-Live has this capability.
OpenAI’s newsroom account announced on X that it is retiring Advanced and Standard voice from ChatGPT Voice on December 11, 2026, saying voice usage has nearly doubled since GPT-Live launched in July and that virtually all voice users now use GPT-Live. The same text appears in OpenAI’s release notes.
OPENAI ๐ฅ: Advanced and Standard voice modes on ChatGPT will be retired on December 11!
Does it mean that we are expecting another realtime voice model upgrade to happen before that?
— ๐จ AI News | TestingCatalog (@testingcatalog) Nov 11 00:53
TestingCatalog quoted OpenAI’s post at 00:53 UTC on 11 November and asked whether another realtime voice model upgrade could come before December 11. That is the poster’s question; OpenAI has not said.
Three Voice Stacks, Down to One
The Help Center describes how the three options differ. Standard voice “chained three models together”: speech-to-text, a large language model and text-to-speech. Advanced voice ran on a turn-based model that “had to wait for the user to stop speaking before responding”. GPT-Live is described as “a full-duplex voice model, meaning it can listen and speak at the same time”.
OpenAI also acknowledges that “these model transitions can be challenging” for people used to the older voices’ style, and points them to a Help Center article on model changes.
The Structural Read
As we read it, the change folds three separate voice stacks into one model line, while two named exceptions, live video and screen-sharing, still depend on the older Advanced voice.

Three Implications
FOR CHATGPT VOICE USERS Anyone with Advanced or Standard selected will be defaulted to Live voice on December 11, OpenAI says; conversations stay in history.
FOR CUSTOM GPT BUILDERSOpenAI says voice with custom GPTs keeps using Advanced voice until their deprecation on December 11, 2026.
FOR READING THE TIMELINE By our arithmetic, the notice runs 31 days, from November 10 to December 11.
What Is Not Established
OpenAI gives no user counts, no share of voice sessions by mode and no figure behind “nearly doubled”. It does not say when GPT-Live will support live video or screen-sharing. TestingCatalog asked on X whether another realtime voice upgrade will come before December 11; OpenAI has not said. The 31-day and two-of-three figures are our arithmetic on OpenAI’s own pages.

This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
OpenAI says it is retiring Advanced and Standard voice in ChatGPT on December 11, 2026, 31 days after its notice by our arithmetic. Its Help Center says GPT-Live becomes the default, while Advanced voice stays behind live video and screen-sharing until GPT-Live supports them.
