OpenAI's GPT-Live can listen and speak at the same time using a full-duplex architecture. Complex questions get handed off to GPT-5.5 in the background, which drastically improves response quality. GPT-Live-1 is available now for paying ChatGPT users, with a mini version for free accounts. API access is coming soon.

OpenAI has launched GPT-Live, a full-duplex ChatGPT voice that listens and speaks at once, with live translation. It rolls out to all users, free ones too.

It’s OpenAI’s “smartest voice model” yet.
