What powers LiveAvatar?
LiveAvatar is built on HeyGen's industry-leading hyper-realistic avatar research, exposed as a realtime API for developers and enterprises.

LiveAvatar Launches with GPT-Live-1
LiveAvatar is a launch partner for OpenAI's GPT-Live-1, pairing voice that can listen and speak at the same time with a realtime avatar.
