Muse Agents SDK
Meta's open-source SDK for building and orchestrating multi-agent systems on top of its Muse model family.
Overview
Meta released the Muse Agents SDK on October 14, 2026, an open-source (Apache 2.0) Python and TypeScript framework for defining agent roles, tools, and handoff logic. It natively supports Muse Spark and Muse Code, and reaches other models through an OpenAI-compatible adapter. The release ships with built-in tracing and evaluation hooks compatible with Meta's internal agent-eval harness, reference agents for coding, research, and customer-support workflows, and integrations with WhatsApp Business and the Meta Enterprise Platform for deployment.
