Summary

Meta released Muse Code beta with Muse Spark 1.2, positioning it as a third coding-agent option next to Claude Code and Codex. Its key differentiators are parallel sub-agents in isolated worktrees, persistent background agents, and local event logging for crash recovery, making it suited for long-running tasks on large repos.

meta released muse code beta with muse spark 1.2. feels like the first proper third option next to claude code and codex. the model is fine, but the setup is more interesting. parallel sub agents run in isolated worktrees so they dont mess with your main code. background agents stay active across the session and keep context. everything gets written to a local event log, so recovery after a crash is possible. looks built for longer running work on large repos rather than short tasks. one line install. has anyone actually run a serious multi hour task with it yet?
