Muse Spark

Summary: The 30-Second Answer Yes, it is free, but metered. You get a weekly token allowance; when it runs out you wait for the reset or upgrade. Power is $20/month for 500M Muse tokens a week, Max is $100/month for 3B. No feature is behind the paywall. Paying buys volume, not capability. US only for now. Meta’s own help page says Muse “and Muse subscriptions are in limited testing and aren’t available in all locations yet.” Four ways in: iPhone, Android, the web at muse.ai, and WhatsApp. The Mac app arrived on 17 September and is a direct download from Meta, not a Mac App Store install. Glasses are “coming soon.” It does not run on your computer. Every task executes inside a dedicated Linux virtual machine in Meta’s cloud. The Mac app is the bridge that lets that remote agent reach your local Files, Mail, Messages, Calendar and Notes. It asks before anything irreversible. Sending, buying and writing to connected accounts all need your approval, and every outbound network request is gated. Meta shipped Muse on 8 September 2026 and it went to number one on the US App Store inside ten days. It is the company’s first serious productivity product, and the pitch is not “another chatbot” but an agent that finishes tasks: clears your inbox, books the trip, fills the form, places the order. ...

Summary: Muse Glimmer in 30 Seconds Muse Glimmer is a 30 billion parameter agentic model released by Meta Superintelligence Labs on August 10, 2026. The weights are open under Apache 2.0. No cloud needed. Four-bit quantization shrinks the language model to under 20 GB, so it runs on a single consumer GPU with 24 GB or 32 GB of memory. It reads text and images, and returns text. Default context window is 128K tokens, and the model supports more. It clears its size class on agentic tests: 75.5 on MCP Atlas (Gemma4-31B 54.2, Qwen3.6-27B 62.5). On math, 94.7 on AIME 2026. The bundled DFlash drafter speeds generation up 3.1x on an RTX 5090 and 1.8x on an M5 Max. It is distilled from Muse Spark, Meta’s cloud model, so the big model’s agentic behavior is transferred into a small one. On the same day Zuckerberg announced that the weights for Muse Spark 1.2, Meta’s flagship model, will be opened too. No date, just “soon.” An AI agent normally means an API key, an internet connection and a bill that ticks up with every request. Meta just tried the opposite. ...
