Meta Expands Muse With Spaces Feature and Low-Cost Ember Model for High-Volume Agent Work
By James Dargan · · 1 min read
Meta has added two new pieces to its Muse AI ecosystem: Spaces, a way to organize ongoing projects with its Muse agents, and Muse Ember, its lightest and most cost-efficient model yet.
Spaces are topic-based workspaces in the Muse sidebar where the agent works toward a specific goal, such as planning a vacation, tracking holiday gifts or organizing a wedding. Meta said users can describe an idea in chat and Muse will build a tracker, planner or project board, while connected third-party apps keep each Space updated automatically with information such as concert dates or price changes. Founder and CEO Mark Zuckerberg said on X that he had used it to build a BBQ game, an event tracker and a home control dashboard.
Released by Meta Superintelligence Labs on Monday, Ember is designed for repetitive agent tasks such as tool calls, coding subtasks, routing and long document parsing. Priced at 10 cents per million input tokens, it undercuts Anthropic’s Haiku and OpenAI’s Luna and competes with open source models such as DeepSeek V4.1 Flash. It is built to pair with the larger Muse Wonder, which plans tasks while Ember handles volume, and can process text, images and audio.
Muse agents reached 10 million users in the U.S. and Canada within two months of launch.
