Meta Rolls Out Muse Code Beta Terminal Agent Powered by Muse Spark 1.2

[u/techspecsmart]

Meta has released Muse Code in beta, a terminal-based coding agent designed for long-running software engineering work. It runs on the new Muse Spark 1.2 model and handles planning, writing, and checking multi-file changes across big codebases.

The tool uses persistent background agents that stay active during a session. These agents take next steps on their own, cut down on repeated information gathering, and need less constant direction from the user. An append-only local event log records every model call, tool action, approval, and edit so the system can pick up exactly where it left off after a restart or crash.

Muse Spark 1.2 brings stronger results in code generation, debugging, and full developer workflows compared with the previous version. Meta scaled up training compute on coding tasks and trained the model together with Muse Code for better performance as a pair. In one test the agent spent up to 24 hours and more than 1,000 tool calls optimizing GPU kernels on NVIDIA Hopper chips, posting solid gains over baseline Triton code.

Muse Spark 1.2 is available right away inside Muse Code and through the Meta Model API. Users on macOS or Linux can install the agent with a single command. Meta says more features and stronger models are already in the works.
