Meta Launches Muse Code Programming Agent, Supports Multi-File Code Changes

Meta launches Muse Code (Beta), a terminal programming agent designed for long-cycle software engineering, powered by the Muse Spark 1.2 model. Muse Code can plan, implement, and verify complex multi-file changes in large codebases, and with the support of persistent sub-agents, it resolves engineering challenges faster, more accurately, and with less intervention, improving development efficiency.
