## Key points

- Meta launches beta coding agent for large software repositories.
- Muse Code uses parallel agents in isolated worktrees.
- Meta aims to challenge Codex and Claude Code on cost.

## Summary

Meta has launched Muse Code, a beta terminal-based AI coding agent designed to help developers complete complex engineering work across large software repositories. The release matters because it places Meta more directly in competition with OpenAI’s Codex and Anthropic’s Claude Code, as the company seeks a stronger position in enterprise AI tools.

Muse Code uses Meta’s Muse Spark coding model and can plan changes, write code and validate results. For larger jobs, it divides work among parallel sub-agents in isolated worktrees, leaving the developer’s working copy untouched; Meta says it tested the approach by building six game features simultaneously without conflicts. Meta’s AI chief Alexandr Wang said the product could be particularly competitive on cost, following the company’s broader investment in AI and recent expansion into enterprise customer-support agents.
