Meta launched Muse Code in beta on August 5 — a terminal coding agent for macOS and Linux powered by Muse Spark 1.2, running multiple persistent subagents that plan changes, write code, and validate results across large repos. Standard pricing is $1.25 input / $4.25 output per million tokens; the Contributor tier drops that to $0.10 / $0.20 in exchange for letting Meta train on your usage and feedback. That is an explicit, quantified price on your source code as training data — roughly 12x on input and 21x on output — and it's the number to put in front of anyone choosing a terminal agent on cost alone.
