Meta Platforms has launched Muse Code, its first terminal-based AI coding agent, now available in beta for macOS and Linux. Powered by the new Muse Spark 1.2 model, Muse Code is designed to handle complex software engineering tasks across large code repositories, coordinating multiple sub-agents that work in parallel in isolated environments. The tool features a crash-safe runtime with a local event log, enabling it to resume work after interruptions. Meta positions Muse Code as a more affordable alternative to rivals, offering a pay-as-you-go pricing model with a discounted Contributor tier that requires users to allow Meta to use their data for training. The launch intensifies competition with Anthropic's Claude Code and OpenAI's Codex, as Meta seeks to monetize its massive AI infrastructure investments. The release follows a disappointing earnings report that saw Meta's shares decline.
