# Meta Launches Muse Code: Terminal AI Agent for Large Codebases

> Meta has released Muse Code in beta, a command-line coding agent aimed at the messy reality of large codebases rather than toy examples. Powered by a model called Muse Spark 1.2, it plans a set of changes, writes the code, and then checks its own work across a repository, positioning Meta squarely against Claude Code, OpenAI's Codex, and Google's coding tools. The technically interesting trick is parallelism. Instead of editing one thing at a time, Muse Code spins up multiple sub-agents that each work in an isolated copy of the repo, so they can build several features at once without stepping on each other. In Meta's testing it shipped six game features simultaneously without merge conflicts, which is the kind of coordination problem that usually breaks automated tools. Pricing lands at 1.25 dollars per million input tokens and 4.25 for output, with a steep discount for cached input. The launch is another sign that the frontier labs now see the terminal, not the chat window, as the battleground for AI that does real engineering work rather than just suggesting snippets.
