Meta just released Muse AI assistant for personal tasks, powered by Muse Spark 1.3, Meta's latest model for longer-horizon agentic work - it can connect to email, calendars, shopping, payments and other services, then keep working after the app closes. - each user gets a Muse Secure VM, with a separate Sentinel agent that checks outbound data and actions before they reach the network. - Meta is making Muse free to use for up to 100M tokens per week, with subscription plans for people who use more compute - Sensitive actions such as purchases or emails require user approval, while credentials stay in Secure Credential Storage so Muse cannot read passwords or payment details. - the model, Muse harness, deterministic code and classifiers screen prompt injections before hostile content can enter the model's context. - currently it launches for U.S. users on web, iOS, Android and WhatsApp, with free access plus $20 and $100 monthly tiers for heavier usage. - the security design moves the trust boundary beyond model behavior into VM isolation, credential separation and a kernel-enforced gate on network actions.
