Meta‘s consumer AI agent Muse now supports real-time calling and video chat for all U.S. users through a feature called Muse Voice. First introduced at Meta‘s Connect developer conference in September, the capability is powered by two new model technologies, Muse Realtime Avatar and Muse Realtime Voice, which produce the animated avatar that users talk to while asking questions or handing off tasks.

Meta‘s default avatar is a cute animated character nicknamed Jolly, and users can customize it into a person, animal, or other character. The company believes anthropomorphizing Muse can make consumers feel more connected to the agent, and says the avatar uses subtle expressions and gestures matched to the conversation’s tone. Meta announced the rollout via blog post and on X; its chief AI officer, Alexandr Wang, demonstrated the feature with a Muse that appeared as a fluffy white dog. When Wang joked that his meme-posting on X may have gotten him in trouble with his boss, the avatar suggested adding disclaimers to memes that could be misinterpreted as Meta endorsing anything risque.

The rollout lands just before Meta plans to launch a Tamagotchi-like wearable for Muse before the end of the year, where the avatar will appear on a small screen and carry out tasks. Real-time conversations currently work on mobile, web, and Mac, with future support planned for Meta‘s AI Glasses and the upcoming Muse Charm hardware.
