Overview
Muse Code is Meta's terminal-native coding agent, announced in August 2026 and taken out of beta at the end of that month. It runs locally on macOS and Linux, signs in with a Meta Model API account, and uses Meta's closed-weight Muse Spark models (including Muse Spark 1.3) for agentic coding. After leaving beta it added inter-session messaging, multi-agent workflows, rewind, a TypeScript SDK preview, and monthly subscription plans alongside pay-as-you-go API usage.
