Meta releases Muse Code agent to compete with Grok and Gemini

Meta has launched Muse Code, a terminal-based AI coding agent powered by its Muse Spark 1.2 model. Designed to execute tasks, edit files, and run tests directly, it scored a reported 59% on the DeepSWE 1.1 benchmark, outperforming Grok Build 4.5 and Gemini 3.6 Flash. This marks a strategic shift for Meta toward direct, finished developer tools.
