Meta just updated its coding model to Muse Spark 1.2 and, in the same breath, opened up a beta for Muse Code — a terminal coding agent designed to work alongside it. The company says it trained the model and the agent together so the two are more tuned to each other's workflows.
Muse Code can plan modifications in large codebases, write the code, and verify the results. When a task gets too big, it breaks the work into subtasks and hands them to different agents running in isolated workspaces, so nothing directly touches your current workspace. Every model call, tool execution, and file modification is first written to a local event log. Muse…
