If you are building a conversational AI agent, you should now plan for persistent, avatar-based video interactions instead of just text or voice. Meta just made that real by letting US users video chat with their customizable Muse AI avatar inside Messenger and Instagram.
What changed
Meta's Muse AI agent, previously a text-and-voice assistant represented by a static animated avatar, can now appear as a live, expressive animated face during video calls. The avatar lip-syncs, blinks, and gestures based on real-time speech and sentiment. Users activate it by saying "Hey Meta" during a video call, and the avatar takes over the screen as the AI responds.
This is not a gimmick. It is a production deployment of a persistent avatar that represents a single user's preferences and history across calls. Meta says the avatar learns your communication style over time, so it can speak in your tone and reference past conversations.
What it means for developers
Three practical implications stand out for anyone building AI agents:
- Avatar state management matters. The Muse avatar maintains context across sessions. If you are building a similar system, you need a persistent user profile that stores conversation history, tone preferences, and visual customization choices.
- Real-time avatar rendering is now a baseline expectation. Users will expect any AI agent with a face to react in real time during video calls. That means you need a rendering pipeline that can process speech-to-text, sentiment analysis, and animation generation within a few hundred milliseconds.
- Customization is a feature, not a novelty. Meta lets users pick skin tone, hair style, outfit, and accessories. If your agent has a visual representation, giving users control over its appearance increases engagement.
The hardware angle
Meta is also planning a Tamagotchi-like wearable device that brings Muse to life as a physical companion. That device is not shipping yet, but the video call feature is the software foundation for it. Developers should watch for an SDK or API that allows third-party apps to embed the Muse avatar, similar to how Meta opened Messenger Platform for bots.

A video-call avatar changes the product surface from generated media to a live interaction with expectations around identity, consent, and failure handling.
The engineering question is not only latency; it is also how clearly the system discloses automation, preserves a transcript or handoff, and prevents a convincing avatar from making commitments it cannot keep.
