Meta releases Muse Spark 1.1 with public agent API access
Meta released Muse Spark 1.1 through its consumer assistant and a public-preview API, adding long-horizon context management, multi-agent orchestration, tool use, and computer control to a broadly accessible frontier model.
Why it moved the index
Meta's dated launch and linked evaluation report document a released model that can plan, delegate to subagents, retain a million-token working context, operate computers, and act across external tools. Consumer availability plus a public-preview API converts the autonomy gain into deployment, while Meta's frontier-risk evaluation supports but does not eliminate residual control and misuse concerns.
