Meta has introduced Muse Code (beta), a terminal-based AI coding agent powered by its latest Muse Spark 1.2 model. The company said Muse Code marks its next step toward more capable AI models, with larger models planned for future releases. Muse Code featuresMuse Code uses a simple agent loop alongside multiple persistent asynchronous background agents that work with the main coding agent to handle complex, multi-step software engineering tasks. The earlier model evaluated candidate solutions based on how well they satisfied the required objectives, producing a scalable training dataset for Muse Spark 1.2. Pricing and AvailabilityMeta said Muse Code (beta) is available for macOS and Linux.
