Meta launches Muse Code, an AI agent for large code bases

Muse Code, now in beta, handles complex software engineering tasks across large repos by launching parallel sub-agents in isolated worktrees. Powered by Meta's Muse Spark model, it can be installed with a single command. Meta positions it as a cost-effective alternative to OpenAI's Codex and Anthropic's Claude Code.
