Meta Releases Muse Code Beta and Muse Spark 1.2
Zuckerberg posts about terminal agent for full engineering work on large repositories.
Mark Zuckerberg announced the beta release of Muse Code, a terminal coding agent that plans changes, writes code, and validates results across large codebases. The agent is powered by Muse Spark 1.2, a coding-focused model update. The post included a curl command to install via dev.meta.ai. Retweets and quotes from Meta engineers and researchers repeated the announcement and shared benchmark details and install steps.
Releasing Muse Code in beta today. It's a terminal coding agent that takes on complete software engineering tasks across large repos: planning changes, writing code, validating the results. Powered by Muse Spark 1.2, a coding-focused model update.

muse code in beta is live. first coding agent from msl, built on muse spark 1.2. install: curl -fsS | bash here's what you should know:
the harness architecture: multiple specialized agents coordinate in parallel on the same task. they persist across your session, building context instead of starting cold each time. for complex work, sub-agents fan out into isolated worktrees so your working copy stays clean.
we co-trained the model and agent together. the result: higher first-attempt success on tool calls, cleaner plan execution, less time re-prompting. 1m token context window. one cool thing: we pointed it at kernel optimization on nvidia hopper and let it run. 1,000+ tool calls…
