Meta wants a seat at the table developers actually use. The company has launched Muse Code, an AI coding agent that runs in the terminal and takes direct aim at the fast-growing market for software that writes software.

The tool is built on Meta’s latest model. Muse Code is powered by Muse Spark 1.2, and works on macOS and Linux, running as a command-line agent rather than a plugin bolted onto an existing editor.

Its headline feature is autonomy. Muse Code can run persistent background agents that keep working on tasks while a developer does something else, part of the shift from AI as autocomplete to AI as a tireless junior colleague.

The sharpest weapon, though, is price. Meta is offering a data-sharing tier at just $0.30 per million tokens, a rate that badly undercuts rivals for developers willing to let their code help train the model.

That trade is the whole strategy. By exchanging a rock-bottom price for access to real-world coding data, Meta can both win users and feed the very system it is trying to improve.
