This is absolutely incredible.
Mark Zuckerberg’s Meta just released a revolutionary new AI coding agent.
The new Muse Code is so unbelievably cheap and intelligent -- once again we see the clear trend of AI getting cheaper and cheaper.
And it comes with a revolutionary new approach to multi-agent collaboration, that could transform the workflow of so many developers.
Powered by their most powerful model ever -- this is going to make major impact on the entire AI coding ecosystem.
Demo stage #1: A drone fly through video to be given to Muse Code to integrate into a landing page
Muse Code is a terminal-based agent designed from the group up to handle complete software engineering tasks across large repositories — putting it directly against tools like Claude Code and Codex.
But it's not just yet another coding assistant in your terminal.
Meta is building it around a bigger idea: coding agents should work for hours, coordinate multiple workers, survive failures, and keep making progress autonomously.
Let's check out all the most amazing features it comes with -- including how incredibly inexpensive it is.
Demo stage #2: Asking Muse Code to integrate the video into the website with various marketing copies at different points in the video -- directly from the terminal:
1. Persistent background agents — less repeated work
Most coding agents create a subagent, give it a task, collect the result, and destroy it.
Muse Code instead keeps asynchronous background agents alive throughout the session.
They can:
investigate different parts of the codebase
retain context they've already gathered
work while the main agent continues
report useful discoveries back later
For us developers, this means less repeated exploration of large repositories.
Instead of one agent repeatedly searching hundreds of files, you get specialized workers that gradually build knowledge of the project while the main agent keeps coding.
Demo stage #3: Muse Code intelligently integrates the video into the website, with all the marketing copies and the final call to action:
2. Incredibly low cost — run coding agents for a fraction of the price
I’ve just added a practical guide on Muse Code in the Coding Beauty community — covering setup, API key configuration, autonomous bug fixing, parallel feature development, complex refactoring, and long-running optimization loops.
And as new AI coding tools and techniques emerge, I’ll keep adding practical guides and workflows to help you actually put them to work.
