Meta Muse Code: New AI Terminal Agent for Developers

Meta has launched Muse Code, a new terminal coding agent now in early beta. This agent is powered by Muse Spark 1.2, a coding-focused update to Meta’s Muse Spark model line. Muse Code is designed for repository-scale work. It can plan changes, write code, and validate results with less human intervention. The agent also runs multiple persistent subagents for multi-step tasks, reducing the need for constant guidance. What's interesting is how it's built. Muse Code uses a main agent loop with async background agents that stay active throughout a session. This helps avoid re-gathering context. It also keeps a local event log, allowing the agent to resume after a crash. Muse Spark 1.2, which powers Muse Code, improves code generation, debugging, and understanding of codebases. It is available today in Muse Code and through the Meta Model API. The bottom line: Meta is making a clear bid in the developer workflow space with Muse Code, and you can try the beta now.
