Meta’s personal AI agent Muse has attracted millions of users within two weeks of launch, an early response Mark Zuckerberg described as unusually strong for a Meta product. In a September 25 interview, Meta CEO Zuckerberg said Muse will be integrated across the Ray-Ban smart-glasses lineup, allowing users to set custom wake words instead of saying "Hey Meta." The product combines a trained model with memory, task tracking, real-time voice interaction, animated avatars and an autonomous "heartbeat" that periodically checks whether it can advance a user’s goals. Each agent operates in a Secure VM (isolated virtual machine), with encrypted data storage, protected credentials and a Sentinel security agent that monitors data flows and can block risky actions or request user approval. Zuckerberg said Meta is bringing together its long-running investments in the metaverse, smart glasses and large AI models. He also called Llama 4’s performance the company’s most frightening setback, saying Meta reorganized its AI effort into the Meta Super Intelligence Lab and is preparing a new generation of models. Meta has largely deployed an Ohio cluster exceeding 1 gigawatt and is building a 5-gigawatt cluster in Louisiana. Zuckerberg said sufficiently large computing clusters could reach artificial general intelligence, or AGI (human-level general-purpose AI), while acknowledging that architecture research remains important because current systems are far less efficient than the human brain. He framed alignment (training AI to follow users’ intentions and values) as a product requirement rather than merely a regulatory burden.
