Meta released Muse Code, a command-line coding assistant now in beta testing, together with a new coding-focused model called Muse Spark 1.2. The assistant keeps helper agents running through a session and records every step so it can resume after a crash, and Meta reports it improved GPU code over runs lasting up to 24 hours. Installation is limited to macOS and Linux.

What changed

Meta's previous coding model, Muse Spark 1.1, had no accompanying command-line agent.

What it unlocks

Running a coding agent in the terminal that keeps helper agents alive across a session and resumes exactly where it stopped after a crash.

  • 1,000+ tool calls per task
  • up to 24 hours of running
  • macOS and Linux install

What you need to act on it
