Meta launches Muse Code, an AI agent for large code bases

Meta has launched Muse Code, an AI-powered terminal agent designed to assist programmers with complex tasks across large code bases. The tool aims to compete with offerings from OpenAI and Anthropic by providing a more cost-effective solution for enterprise software engineering.
Why it matters
This release marks Meta's attempt to gain ground in the competitive AI coding assistant market by focusing on scalability and cost efficiency.
Meta, considered a bit of a straggler in the AI harnesses realm, is making strides to catch up. This week, the company released a new terminal coding agent aimed at programmers looking for assistance with complex tasks across large software code bases.
Muse Code, which is currently available in beta, can accomplish “complete software engineering tasks across large repos,” Meta CEO Mark Zuckerberg said in a social media post on Wednesday. Those tasks include “planning changes, writing code, validating the results,” he added.
Code, which can be installed with a single command, is powered by Meta’s previously released coding model, Muse Spark. It handles large projects by launching its own agents, which then work simultaneously.
