Meta launches Muse Code AI coding agent for macOS and Linux
Meta has unveiled Muse Code, a beta terminal-based AI coding agent now available for macOS and Linux. This tool, leveraging the Muse Spark 1.2 model, aims to assist developers in managing complex software engineering tasks efficiently. Unlike other coding assistants, Muse Code currently lacks a dedicated application interface, instead functioning within terminal environments. It is designed to facilitate tasks such as code generation, debugging, and workflow coordination, documenting actions through a local event log.
