GPT-Live

Full-duplex voice models GPT-Live-1 and mini, launched July 8, 2026 to replace Advanced Voice Mode's speech-to-text → LLM → text-to-speech pipeline. They listen and speak at once, so they handle interruptions and live translation, and delegate hard queries to GPT-5.5 mid-conversation. Mini is default for free users; no API at launch, waitlist only.
