Meta launches Muse Code AI coding agent for macOS and Linux

AI-summarised brief · reviewed before publication

Meta has released Muse Code, a terminal‑based AI coding agent now in beta for macOS and Linux. The tool, powered by the Muse Spark 1.2 model, can plan changes, write and validate code, and coordinate persistent background agents throughout a session. It logs model calls, tool use, approvals, and edits, enabling work to resume after crashes. Installation requires a single command, and the agent supports built‑in commands for planning, stress‑testing, and goal‑driven development across large repositories. The release follows Meta’s earlier Muse Spark 1.1 launch and API expansion.

💡 Why It Matters

  • · By offering a lightweight, command‑line coding assistant that persists across sessions, Meta provides developers with a new workflow that blends AI automation with traditional terminal tools, potentially accelerating large‑scale software projects.
