OpenAI GPT-Live: Full-Duplex Voice Models Replace Advanced Voice Mode
OpenAI
OpenAI released GPT-Live on July 8, a new generation of full-duplex voice models that can listen and speak simultaneously, replacing Advanced Voice Mode. Two variants ship: GPT-Live-1 (paid tiers) and GPT-Live-1 mini (free). The model handles natural backchanneling, delegates complex queries to a background frontier model, and is rolling out across iOS, Android, and ChatGPT.com.
Why it matters
Full-duplex architecture enables natural interruptions and real back-and-forth that previous half-duplex voice AI could not match, opening a new front against ElevenLabs, Cartesia, and Google.
Importance: 4/5
New voice architecture replaces Advanced Voice Mode for all ChatGPT users; multiple independent confirmations
