Meta Launches 'Muse Code' Autonomous AI Agent for Multi-Step Software Engineering

Meta has entered the agentic coding space with Muse Code, an autonomous system that operates directly inside git repositories to resolve complex issues.

Meta today announced Muse Code, a specialized AI agent built for end-to-end software maintenance and feature implementation across large codebases.

Unlike traditional autocomplete tools, Muse Code parses repository dependency graphs, writes regression tests, and opens pull requests with verified code changes.

Meta reports that internal engineering teams using Muse Code experienced a 40% reduction in time spent resolving routine bug backlog items.
