Meta is rolling out its first coding agent called Muse Code
Mark Zuckerberg posted this:
"Muse Code runs specialized background agents that stay active your whole session, so they build up context over time instead of starting from scratch on every task.
When a job is big enough, it fans out to separate sub-agents working in parallel in isolated worktrees. Your working copy is never touched. In testing we had it build six features for a game simultaneously with no collisions."
"Pricing: It's easy and low-cost to get started. Install Muse Code with one line and you can start on our contributor tier."
