Muse Code: Complete Guide to Meta's New AI Coding Agent

Ethan

Last update :

Muse Code is a new AI-powered coding agent from Meta designed to assist developers with software engineering tasks.

It is powered by Meta's Muse Spark 1.2 model and is currently available in beta.

Muse Code can help write and debug code while handling longer and more complex development tasks.

It can also work with multiple sub-agents at the same time to handle different parts of a development workflow.

The tool is designed to work across large codebases and can help plan changes before implementing them.

Muse Code also includes a persistent activity log that allows work to continue after interruptions or crashes.

The service currently uses a pay-as-you-go pricing model based on AI token usage.

Meta's launch puts Muse Code directly into the rapidly expanding AI coding-agent market alongside tools from OpenAI and Anthropic.

Final Thoughts

Muse Code is one of the newest AI coding tools of 2026 and is worth watching as Meta expands further into AI-assisted software development
